find the 30th percentile for the standard normal distribution b. find the 30th percentile for a normal distribution with mean 10 and std. dev. 1.5 35. x is normal with a mean of 50 and standard deviation 4. find the probability that a sample of size 9 has mean between 48 and 53.

Answers

Answer 1

The 30th percentile for the standard normal distribution is -0.524. This means that approximately 30% of the data falls below -0.524 in a standard normal distribution.

In other words, if we have a large set of normally distributed data with a mean of 0 and standard deviation of 1, about 30% of the data points will have a value less than -0.524.

For a normal distribution with a mean of 10 and standard deviation of 1.5, finding the 30th percentile involves finding the value x for which 30% of the data falls below x.

To calculate this, we can use the Z-score formula, which relates any value in a normal distribution to its corresponding percentile in the standard normal distribution.

By substituting the given values into the formula and solving for x, we find that the 30th percentile for this specific normal distribution is approximately 9.085.

To find the probability that a sample of size 9, taken from a normal distribution with a mean of 50 and standard deviation of 4, has a mean between 48 and 53, we need to calculate the z-scores for these values and then find the probability associated with that range.

The z-scores are calculated by subtracting the mean and dividing by the standard deviation. In this case, the z-score for 48 is (48 - 50) / 4 = -0.5, and the z-score for 53 is (53 - 50) / 4 = 0.75.

Using a standard normal distribution table or a calculator, we can find the probabilities associated with these z-scores and then subtract the probability of the lower z-score from the probability of the higher z-score to get the desired probability.

Answers

The ending balance in accumulated other comprehensive income on December 31, 2019, is $10,200 (credit balance).

To determine the ending balance in accumulated other comprehensive income on December 31, 2019, we need to analyze the changes in comprehensive income and other comprehensive loss. The net income of $12,000 and other comprehensive loss of $3,000 (net of tax) for the year ended December 31, 2020, indicate that the comprehensive income for the year is $9,000 ($12,000 - $3,000).

The ending balance in accumulated other comprehensive income can be calculated by adding the comprehensive income for the year to the beginning balance in accumulated other comprehensive income. Given that the ending balance on December 31, 2020, is $6,800 (credit balance), we can derive the beginning balance in accumulated other comprehensive income on December 31, 2019, by subtracting the comprehensive income for the year ($9,000) from the ending balance on December 31, 2020.

Answers

Resolving the different perspectives on monitoring employee activity is difficult to determine where work ends and personal life begins. (option b)

The issue of monitoring employee activity has become increasingly complex and challenging to resolve due to various factors. In this response, we will delve into four key reasons that contribute to the difficulty of addressing different perspectives on this matter.

These reasons include the absence of federal laws for video surveillance in public areas, the blurred boundaries between work and personal life, the legality of employers wiretapping employees' personal phones, and the impact of technological advances in the workplace.

Another challenge arises from the difficulty in determining where work ends and personal life begins. With the increasing use of technology and remote work arrangements, the line between professional and personal activities can become blurry. Employees often use personal devices for work-related tasks, and vice versa, making it challenging to separate work-related monitoring from personal privacy. This ambiguity makes it hard to establish a consensus on the extent to which employee activity should be monitored.

the blue catfish (ictalurus furcatus) is the largest species of north amercian catfish. the current world record stands at 143 pounds, which was caught in the john h. kerr reservoir (bugg's island lake) located in virginia. according to amercian expedition, the average weight of a blue catfish is between 20 to 40 pounds. given that the largest blue catfish ever caught was at the john h. kerr reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. a) if you going to test this claim at the 0.05 significance level, what would be your null and alternative hypotheses?

Answers

The t-value using the sample mean, sample standard deviation, sample size and the hypothesized mean of 40 pounds.

The calculated t-value is greater than the critical t-value, we would reject the null hypothesis in favor of the alternative hypothesis, concluding that the mean weight of blue catfish in the reservoir is indeed greater than 40 pounds.

To test the claim that the mean weight of blue catfish in the John H. Kerr Reservoir is greater than 40 pounds, we can set up the null and alternative hypotheses as follows:

Null Hypothesis (H0):

The mean weight of blue catfish in the John H. Kerr Reservoir is 40 pounds or less.

Alternative Hypothesis (Ha):

The mean weight of blue catfish in the John H. Kerr Reservoir is greater than 40 pounds.

In mathematical notation:

H0: μ ≤ 40

Ha: μ > 40

Here, μ represents the population mean weight of blue catfish in the reservoir.

By assuming that the average weight of blue catfish in the reservoir is not significantly different from 40 pounds or less, we set up the null hypothesis.

The alternative hypothesis suggests that the mean weight is greater than 40 pounds.

To test these hypotheses, we can perform a one-sample t-test on a sample of blue catfish weights collected from the reservoir.

We can then compare the calculated t-value with the critical t-value at a significance level of 0.05.

Conversely, if the calculated t-value is not greater than the critical t-value, we would fail to reject the null hypothesis and would not have sufficient evidence to conclude that the mean weight is greater than 40 pounds.

It's important to note that conducting the actual statistical analysis requires the collection of a representative sample of blue catfish weights from the John H. Kerr Reservoir and performing the necessary calculations using appropriate statistical software or tools.

When workers identified with the interests of capitalists, Marx called it __________ class consciousness. Group of answer choices misguided budding optimistic false

Answers

When workers identified with the interests of capitalists, Marx called it false class consciousness.

False class consciousness is a concept in Marxist theory that describes a situation where members of the working class adopt the beliefs, values, and interests of the capitalist class instead of recognizing and pursuing their own class interests. Marx argued that the capitalist system inherently creates conditions that obscure the true nature of class relations and exploitation.

According to Marx, the capitalist class holds economic and political power and benefits from the labor of the working class. However, the capitalist class uses various means, such as ideology and cultural influences, to shape the consciousness of the working class. This results in the workers aligning themselves with the interests of the capitalists, often believing that their own success is tied to the success of the capitalist system.

Marx believed that false class consciousness hindered the potential for revolutionary class struggle and collective action by the working class. He argued that by accepting the dominant capitalist ideology, workers remained unaware of their own exploitation and continued to support a system that perpetuated their subjugation.

Marx's concept of false class consciousness emphasized the importance of class awareness and the need for workers to develop a true class consciousness, recognizing their common interests and working towards collective action to challenge and transform the capitalist system.

In summary, false class consciousness refers to the situation where workers adopt the beliefs and interests of the capitalist class, failing to recognize their own exploitation and working against their own class interests. It is a concept that highlights the ideological influence of the capitalist class in shaping the consciousness of the working class.

Answers

The rose gold bracelets sold by Chantel's fine jewelry store are considered price elastic, as an increase in price resulted in an apparent increase in demand and sales.

Based on the information provided, Chantel raised the price of her rose gold bracelets by $75 to cover unexpected expenses. Surprisingly, she observed an increase in sales at the higher price point. This suggests that the rose gold bracelets are price elastic.

Price elasticity of demand refers to the responsiveness of the quantity demanded to changes in price. When a product is price elastic, an increase in price leads to a proportionately larger decrease in quantity demanded, resulting in a decrease in total revenue. Conversely, a decrease in price would lead to a proportionately larger increase in quantity demanded and total revenue.

This suggests that the demand for these bracelets is relatively elastic, meaning that customers are responsive to changes in price and perceive the higher price as an indicator of increased value, exclusivity, or quality.

Several factors may contribute to this phenomenon. The rose gold bracelets may have unique design elements or craftsmanship that customers are willing to pay a higher price for.

How can I find how many times a bicycle wheel will turn in going three miles?

Answers

To find out how many times a bicycle wheel will turn in going three miles, you need to know the circumference of the wheel. The circumference is the distance around the wheel.

You can use the following formula to calculate the number of wheel rotations:

Number of Wheel Rotations = Distance Traveled / Circumference of the Wheel

1. Determine the circumference of the bicycle wheel. This can be calculated by multiplying the diameter of the wheel by π (pi), which is approximately 3.14159. The diameter is the distance across the wheel passing through its center.

2. Measure the distance you want to travel in miles. In this case, it is three miles.

3. Plug the values into the formula and calculate the number of wheel rotations.

For example, let's assume the diameter of the bicycle wheel is 26 inches. To find the circumference, we multiply the diameter by pi:

Circumference = 26 inches × 3.14159 ≈ 81.68 inches

Now, convert the distance of three miles into inches. Since one mile is equal to 63,360 inches:

Distance Traveled = 3 miles × 63,360 inches/mile = 190,080 inches

Finally, calculate the number of wheel rotations:

Number of Wheel Rotations = 190,080 inches / 81.68 inches ≈ 2,326.37 rotations

Therefore, the bicycle wheel will turn approximately 2,326 times in going three miles.[tex][/tex]

Answer:So, if we want to know how many revolutions our wheels have to turn, we divide 200 centimeters by 24.92 centimeters/revolution (remember the circumference is how far the wheel goes in one revolution). The number of revolutions is equal to: 200 cm/24.92 (cm/revolution) = 8.03 revolutions.

(a) What is the probability that there is at least 50% red M&Ms in the random sample?

(b) What is the probability no more than one-third of the M&Ms in the random sample are red?

Answers

The binomial distribution, as we are dealing with a sample of M&Ms where each M&M can be considered a success (red) or failure (not red) with a known probability of success.

Probability of a red M&M (success): p = 0.51

Sample size: n = 30

(a) Probability of at least 50% red M&Ms in the random sample:

To find the probability of at least 50% red M&Ms, we need to calculate the probability of having 15, 16, ..., 30 red M&Ms in the sample and sum them up.

P(at least 50% red) = P(X = 15) + P(X = 16) + ... + P(X = 30)

Using the binomial probability formula, where X follows a binomial distribution with parameters n and p:

P(X = k) = (nCk) * p^k * (1 - p)^(n - k)

Let's calculate the probability:

P(at least 50% red) = P(X = 15) + P(X = 16) + ... + P(X = 30)

                  = sum from k = 15 to 30 of [(30Ck) * (0.51)^k * (0.49)^(30 - k)]

You can use a calculator or software to evaluate this sum and find the result.

(b) Probability no more than one-third of the M & Ms are red in the random sample:

To find the probability of no more than one-third red M&Ms, we need to calculate the probability of having 0, 1, 2, ..., 10 red M&Ms in the sample and sum them up.

P(no more than one-third red) = P(X = 0) + P(X = 1) + ... + P(X = 10)

Using the binomial probability formula:

P(X = k) = (nCk) * p^k * (1 - p)^(n - k)

Let's calculate the probability:

P(no more than one-third red) = P(X = 0) + P(X = 1) + ... + P(X = 10)

                            = sum from k = 0 to 10 of [(30Ck) * (0.51)^k * (0.49)^(30 - k)]

a bicycle has 26 inch diameter wheels, the front chain drive with the pedals has a radius of 2.2 inches, and the back dive on the wheel has a radius of 3 inches. how far does the bicycle travel for every rotation of the front chain drive? round to one decimal place.

Answers

For every rotation of the front chain drive, the bicycle travels a distance equal to the circumference of the back wheel. To find the distance the bicycle travels for every rotation of the front chain drive, we need to consider the gear ratio and the wheel circumference.

1. Calculate the gear ratio:

Gear ratio = (Radius of front chain drive) / (Radius of back chain drive)
Gear ratio = 2.2 inches / 3 inches
Gear ratio ≈ 0.7333

2. Calculate the wheel circumference:

Circumference = π × Diameter
Circumference = π × 26 inches
Circumference ≈ 81.68 inches

3. Calculate the distance traveled per rotation of the front chain drive:

Distance traveled = Gear ratio × Wheel circumference
Distance traveled = 0.7333 × 81.68 inches
Distance traveled ≈ 59.9 inches

Therefore, the bicycle travels approximately 59.9 inches for every rotation of the front chain drive, rounded to one decimal place.

1. Your body absorbs caffeine from your bloodstream at a rate of 10% per hour. If you drink a medium


latte with 175 mg of caffeine at 11am, how much will still be left in your bloodstream at 5pm?

Answers

Approximately 93.05 mg of caffeine will still be left in your bloodstream at 5pm after drinking a medium latte with 175 mg of caffeine at 11am.

To calculate the amount of caffeine remaining in your bloodstream at 5pm after drinking a medium latte with 175 mg of caffeine at 11am, we need to consider the rate of caffeine absorption and the elapsed time.

Since your body absorbs caffeine at a rate of 10% per hour, we can calculate the remaining amount of caffeine using the following formula:

Remaining Caffeine = Initial Caffeine * (1 - Rate of Absorption)^Elapsed Time

Let's calculate the remaining caffeine at 5pm, which is 6 hours after 11am:

Elapsed Time = 6 hours

Remaining Caffeine = 175 mg * (1 - 0.10)^6

Remaining Caffeine ≈ 175 mg * (0.9)^6

Remaining Caffeine ≈ 175 mg * 0.531441

Remaining Caffeine ≈ 93.05 mg

Therefore, approximately 93.05 mg of caffeine will still be left in your bloodstream at 5pm after drinking a medium latte with 175 mg of caffeine at 11am.

he following information pertains to the bank of the kamloops. if all banks hold only the required 4 percent of deposits as reserves, then what is the money multiplier? bank of the kamloops assets: liabilities: reserves $3,500 deposits $70,000 loans $66,500 a. 5 cross out b. 10 cross out c. 15 cross out d. 25

Answers

If all banks hold only the required 4 percent of deposits as reserves, then the money multiplier is 25. The correct option is (d).

To calculate the money multiplier, we first need to understand the relationship between reserves, deposits, and the required reserve ratio.

The required reserve ratio is the percentage of deposits that banks are required to hold as reserves by regulatory authorities.

In this case, the required reserve ratio is given as 4 percent, which means that banks must hold 4 percent of their total deposits as reserves. We have that the Bank of Kamloops has reserves of $3,500 and deposits of $70,000, we can calculate the required reserves as follows:

Required Reserves = Required Reserve Ratio * Deposits

                 = 0.04 * $70,000

                 = $2,800

Now, we can calculate the excess reserves, which is the difference between the actual reserves and the required reserves:

Excess Reserves = Reserves - Required Reserves

               = $3,500 - $2,800

               = $700

The money multiplier is the reciprocal of the required reserve ratio. Since the required reserve ratio is 4 percent, the money multiplier can be calculated as:

Money Multiplier = 1 / Required Reserve Ratio

                = 1 / 0.04

                = 25

Therefore, the correct answer is (d) 25, which represents the money multiplier in this scenario. The money multiplier indicates how much the money supply can expand based on the reserves held by banks.

Rectangle ABCD is inscribed in a circle. If the measure of arc AB is 140°, what is the measure of arc BC? F 30° G 40° H 60° J 80°​

Answers

The measure of arc BC is 40°.

Given that a rectangle ABCD is inscribed in a circle, the measure of arc AB is 140°,

We need to determine the measure of arc BC,

Since ABCD is a rectangle, angle DAB is a right angle (90°).

Also, the sides of the rectangle here are acting as the chords of the circle,

So, Chord AB = Chord DC

⇒ arc AB = arc DC = 140°

Also, according to the inscribed angle theorem,

The measure of the inscribed angle is half the measure of the central angle.

Therefore,

2 ∠DAB = arc BCD

arc BCD = 2 × 90°

arc BCD = 180°

arc BCD = arc BC + arc DC

180° = arc BC + 140°

arc BC = 40°

Hence the measure of arc BC is 40°.

The level of inventory that, when reached, drives a new order to be placed to ensure proper inventory is maintained, is known as the reorder point. Your store is operational 156 days per year for business. Your annual demand is 18,575 items of product. The lead time to receive an inbound shipment order to resupply your store is 14 days. When the inventory falls to what approximate level should a new order be placed, using reorder point

Answers

When the inventory falls to approximately 1,832.91 items, a new order should be placed to ensure proper inventory is maintained for being the store operational for 156 business days.

To calculate the reorder point, we need to consider the demand during lead time as well.
First, we need to find the average daily demand:
Annual demand = 18,575 items
Average daily demand = Annual demand / Operational days
= 18,575 / 156
= 119.02 items per day
Next, we need to calculate the demand during lead time:
Lead time demand = Average daily demand x Lead time
= 119.02 x 14
= 1,666.28 items
Now, we can calculate the reorder point:
Reorder point = Lead time demand + Safety stock
We don't have information on the safety stock, so let's assume it's 10% of the lead time demand:
Safety stock = 10% x Lead time demand
= 10% x 1,666.28
= 166.63 items
Reorder point = 1,666.28 + 166.63
= 1,832.91
Therefore, when the inventory falls to approximately 1,832.91 items, a new order should be placed to ensure proper inventory is maintained.

Answers

The simplified expression is 2y² - 9.

To subtract the binomials (-3y^2 - 8) - (-5y^2 + 1), we need to distribute the negative sign to the terms inside the second set of parentheses:

(-3y^2 - 8) - (-5y^2 + 1) = -3y^2 - 8 + 5y^2 - 1

Next, we combine like terms by adding or subtracting the coefficients of the same degree:

-3y^2 + 5y^2 - 8 - 1 = (5y^2 - 3y^2) + (-8 - 1) = 2y^2 - 9

Answers

Based on the information provided, Jameela, who lives in poverty and has a diet mainly consisting of legumes, whole-grain breads and rice, fruits, and a few vegetables, is most at risk of nutrient deficiencies.

Jameela's limited access to a varied and balanced diet puts her at risk of nutrient deficiencies. While legumes, whole-grain breads, rice, fruits, and vegetables can provide essential nutrients, it is important to have a diverse range of food sources to ensure an adequate intake of all necessary vitamins, minerals, and other nutrients.

The heavy veils worn by Jameela may further contribute to her risk of nutrient deficiencies. The veils may limit her approach to sunlight, which is an important source of vitamin D synthesis in the body. Vitamin D is crucial for bone health and overall immune function. If Jameela does not have alternative sources of vitamin D in her diet or through supplements, she may be at risk of deficiency.
