Find the exact value of tan P in simplest radical form. √85 2 N √89​

Answers

Answer 1

Answer:

We can start by using the tangent formula:

tan(P) = sin(P) / cos(P)

We are not given the values of sin(P) and cos(P) directly, but we can use the Pythagorean identity to relate them:

sin^2(P) + cos^2(P) = 1

We can rearrange this expression to solve for sin(P) in terms of cos(P):

sin^2(P) = 1 - cos^2(P)

sin(P) = ±√(1 - cos^2(P))

Now we can substitute this expression into the tangent formula:

tan(P) = ±√(1 - cos^2(P)) / cos(P)

Substituting the given values and simplifying:

tan(P) = ±√(1 - (2/√85)^2) / (1/√89)

tan(P) = ±√(1 - 4/85) * √89

tan(P) = ±√(81/85) * √89 / 1

We want to express tan P in simplest radical form, so we can simplify the square root by factoring out the greatest perfect square factor of the numerator:

tan(P) = ±(√9/√85) * (√89/1)

tan(P) = ±(3/√85) * (√89/1)

Therefore, the exact value of tan P in simplest radical form is ±(3/√85) * (√89/1).

Answers

To solve the triangle MNO, we need to use the law of sines.

First, we can find m by using the following formula:

sin(m)/12 = sin(34)/4

Solving for m, we get:

m = sin^-1(12sin(34)/4) ≈ 56.4°

Next, we can find n by using the law of sines again:

sin(n)/12 = sin(180-34-m)/sin(34)

Solving for n, we get:

n = sin^-1(12sin(112)/sin(34)) ≈ 87.6°

Therefore, m ≈ 56.4° and n ≈ 87.6°.

The null and alternative hypotheses divide all possibilities into: Question 10 options: two sets that overlap two non-overlapping sets as many sets as necessary to cover all possibilities two sets that may or may not overlap

Answers

The null hypothesis represents the default assumption or the status quo, while the alternative hypothesis represents the alternative possibility or the hypothesis that is being tested.

These two hypotheses are mutually exclusive, meaning that if one is true, the other must be false.

The null and alternative hypotheses divide all possibilities into two non-overlapping sets.

In statistical hypothesis testing, the null and alternative hypotheses divide all possibilities into two non-overlapping sets.

These two hypotheses represent different explanations or theories about the data, and they are used to make inferences about the population from the sample data.

The null hypothesis represents the default assumption or the status quo. It states that there is no significant difference or relationship between two variables, or that the observed data is due to random chance alone. The alternative hypothesis, on the other hand, represents an alternative explanation or theory about the data.

It states that there is a significant difference or relationship between two variables, or that the observed data is not due to random chance alone.

The null and alternative hypotheses are mutually exclusive, meaning that if one hypothesis is true, the other hypothesis must be false.

They are also exhaustive, meaning that they cover all possible explanations for the observed data.

By dividing all possibilities into two non-overlapping sets, the null and alternative hypotheses allow us to make a decision about which hypothesis is more likely to be true based on the evidence provided by the sample data.

In order to test the null and alternative hypotheses, we use statistical methods to calculate the probability of obtaining the observed data if the null hypothesis were true.

This probability is called the p-value, and it represents the likelihood of obtaining the observed data or a more extreme result if there were no true effect or relationship in the population.

If the p-value is small enough, we reject the null hypothesis in favor of the alternative hypothesis.

The null and alternative hypotheses divide all possibilities into two non-overlapping sets and provide a framework for making inferences about the population based on sample data.

By testing the null hypothesis and calculating the p-value, we can make decisions about which hypothesis is more likely to be true based on the evidence provided by the sample data.

In statistical hypothesis testing, we use evidence from the data to decide whether to reject the null hypothesis in favor of the alternative hypothesis or not.

What is the answer to #14 the picture is provided. MAKE SURE the radius of your clock is 2 inches.

Answers

Answer:

  see attached

Step-by-step explanation:

You want a clock face with an angle of 240° between the hour and minute hands.

240°

There are 22 possible locations for the minute hand such that the long arc between the hour and minute hands is 240°. The two of these that do not involve fractions of a second are 4:00 and 8:00.

The next occurrence will be 21 minutes 49 1/11 seconds later. And the one after that will be 43 minutes 38 2/11 seconds later, or 1 hour 5 minutes and 27 3/11 seconds after the first occurrence of the pair.

Image

A clock face illustrating 8:00 is attached. You may need to scale it to your desired radius.

You can set your compass to 2" and draw the clock face circle. The points for 12 and 8 can be located by using the 10:00 position as the center of arcs with the same radius. Where those arcs intersect the original circle are the locations of 12 and 8.

Dave is buying popcorn and sodas for his son and his five friends that he brings to the movies (Six kids total). The needs to buy at least one of the two items for each of the six. Popcorn costs $2. 50 per bag and sodas cost $4. 00 each. Dave can spend at most $40. Lets represent the number of sodas he buys and p represent the number of bags of popcorn he buys

Answers

The system of equations that models this scenario is:

p + s ≥ 62.50p + 4.00s ≤ 40

How can it be modeled using a system of equations?

Let p be the number of bags of popcorn.

Let s be the number of sodas Dave buys.

Since Dave needs to buy at least one of each item for all six kids, we have:

p + s = 6 -----(1)

Given:

The cost of a bag of popcorn is $2.50.

The cost of a soda is $4.00.

The total cost of Dave's purchase can be expressed as:

2.50p + 4.00s = C -----(2) where the C is the total cost of Dave's purchase.

Since Dave can spend at most $40, we have:

2.50p + 4.00s ≤ 40 -----(3).

Answers

At 4:00 PM, the distance between Andy and Bill is minimal, about 6.04 miles apart.

Pythagorean theorem is used to find the distance between Andy and Bill at any point in time.

Suppose 3 t hours have passed.

12:00 am.

At that point, Andy moved a remove of 4 miles south from point A, and Charge moved a remove of 5 miles west of point B.

The separation between Andy and Charge is given by

[tex]D(t) = sqrt[(9 - 5t)^2 + (4t)^2][/tex]

To find the time when the distance between Andy and Bill is minimal, we need to find the value of t that minimizes D(t).

To do this, find the derivative of D(t) with respect to t, set it to zero, and solve for t.

dD/dt = (1/2)[2(9 - 5t)(-5) + 2(4t)*(4)]

= -45 + 16t

Setting dD/dt = 0 gives: -45 + 16t = 0

Solving for t gives: t = 45/16 ≈ 2.81 hours

Therefore, the time at which the distance between Andy and Bill is minimal is 3.

48 hours (rounded to the nearest minute).

Note that at this point Andy has traveled a remove of 42.81 = 11.24 miles south of point A, and Charge has traveled a remove of 52.81 = 14.05 miles west of point B.

The separations between them are:

[tex]D(2.81) = sqrt[(9 - 52.81)^2 + (42.81)^2] ≈ 6.04 miles[/tex]

therefore, At 4:00 PM, the distance between Andy and Bill is minimal, about 6.04 miles apart.

How to find the  the probability that the brand W pencils will have a higher mean number of turns needed to sharpen than brand H

Let X be the number of turns needed to sharpen a brand W pencil and Y be the number of turns needed to sharpen a brand H pencil. Then, we are interested in finding P(X > Y), the probability that the mean number of turns needed to sharpen a brand W pencil is higher than the mean number of turns needed to sharpen a brand H pencil.

The difference between the means of X and Y is 4.6 - 5.2 = -0.6. The standard error of the difference between the means can be calculated as:

SE = sqrt[(0.67^2/30) + (0.33^2/30)] = 0.178

The test statistic is:

Which is a better buy, 8oz of steak for
$8.50 or 14 oz of steak for $16.00?

Answers

Answer: The 8 oz steak is a better buy as it has a lower unit price at $1.06 per ounce compared to $1.14 per ounce for the 14 oz steak.

Step-by-step explanation: To determine which is a better buy, we can calculate the unit price of each steak.

The unit price is the price per ounce of steak.

For the 8 oz steak:

Unit price = price ÷ quantity = $8.50 ÷ 8 = $1.06 per ounce

For the 14 oz steak:

Unit price = price ÷ quantity = $16.00 ÷ 14 = $1.14 per ounce

Therefore, the 8 oz steak is a better buy as it has a lower unit price at $1.06 per ounce compared to $1.14 per ounce for the 14 oz steak.

Answers

The probability of a simple event is the likelihood or chance of that event occurring. The formula is P(A) = Number of favorable outcomes / Total number of possible outcomes.

It is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

The formula for the probability of a simple event is:

P(A) = Number of favorable outcomes / Total number of possible outcomes

For example, if we toss a fair coin, the probability of getting heads is:

P(Heads) = 1 (number of favorable outcomes) / 2 (total number of possible outcomes)

So, the probability of getting heads is 0.5 or 50%.

A simple event is an event that has only one possible outcome. For instance, rolling a specific number on a dice, drawing a specific card from a deck of cards, or picking a specific colored ball from a bag of balls are all examples of simple events.

In summary, the probability of a simple event is the ratio of the number of ways the event can happen to the total number of possible outcomes.

The first option with 2-year term and higher monthly payments is better since it results in less total paid in the end.

What is personal loan?

An individual borrower can receive a personal loan to utilise for personal, family, or household needs. The majority of personal loans are unsecured, which means they are not secured by property like a house or a car. Instead, the approval of a personal loan is determined by the borrower's creditworthiness and capacity to pay back the loan. The lender decides the loan amount, interest rate, and repayment conditions for a personal loan based on the borrower's credit score, income, and employment history, among other things. Personal loans are frequently used to pay for unforeseen bills, finance home improvements, and consolidate debt.

For the given plans of payment of 2 years and 5 years we have:

Option 1: 24 monthly payments of $354.56 = $8,534.56 total paid.

Answers

The equation that represents the cost of the rental truck is y = 0.42x + 71. The Option C is correct.

Which equation represents cost of rental truck?

Let x be the number of miles driven

Let y be the cost of the rental truck.

We can set up a system of equations to represent the given information:

For Bob:

y = mx + b

112.96 = 138m + b

For Carl:

y = mx + b

142.78 = 209m + b

Solving for b in both equations, we get:

b = 112.96 - 138m

b = 142.78 - 209m

Setting the two expressions for b equal to each other, we get:

112.96 - 138m = 142.78 - 209m

209m - 138m  = 142.78 - 112.96

71 m = 29.82

m = 0.42

Substituting m into equation for b:

b = 71.

Part B


Approximately how many years from 2009 will it take for the population of wild tigers in Nepal to reach 1,000? Round your answer to the nearest whole number

Answers

Part A

According to the equation, the values of a is a = 2009 + f(a) and b is b = 800 + f(b).

Part B

Approximately it takes 8 years from 2009 for the population of wild tigers in Nepal to reach 800.

To find these values, we need to set the equation for the population of wild tigers equal to 800 and solve for x. The equation becomes 800 = 121(2)ˣ.

Taking the logarithm of both sides, we get

=> log(800) = log(121) + x log(2).

Solving for x, we get

=> x = (log(800) - log(121))/log(2).

Moving on to the second part of the problem, we are asked to determine approximately how many years from 2009 it will take for the population of wild tigers in Nepal to reach 800. Using the equation we derived in Part A, we can plug in values of a and use trial and error to find the answer. However, this can be time-consuming.

Instead, we can use a calculator to get an approximate answer. Plugging in the values for log(800) and log(121) into the equation we derived in Part A, we get x = 7.75.

Therefore, it will take approximately 8 years from 2009 for the population of wild tigers in Nepal to reach 800.

5x+3(8-1)=30 help me lol

Answers

Answer:

1.8

Step-by-step explanation:

5x+3(8-1)=30

5x+24-3=30

5x+21=30

5x=9

x=9/5 or 1 4/5 or 1.8

1.8 is the answer for this question

A researcher was interested in comparing the resting pulse rate of people who exercise regularly and people who do not exercise regularly. Independent simple random samples of 16 people ages 30-40 who do not exercise regularly and 12 people ages 30-40 who do exercise regularly were selected and the resting pulse rate of each person was measured. The summary statistics are as follows. Do Not Exercise X1=72.3 s1=10.3 n1=16 Do Exercise X2=69.0 s2=8.9 n2=12 At the 2.5% significance level, do the data provide sufficient evidence to conclude that the mean resting pulse rate of people who do not exercise regularly is greater than the mean resting pulse rate of people who exercise regularly? Use the critical-value approach.

Answers

For a hypothesis testing by considering two samples related to rate of people who exercise and who do not exercise, the observed t-value < standard so, null hypothesis does not rejected and there is no evidence to support the claim.

We have a researcher who was interested in making a comparison of resting pulse rate of people who exercise regularly and who do not exercise regularly. There is two independent samples. In 1ˢᵗ sample, sample size, n₁= 16

Sample mean, [tex]\bar X_1[/tex] = 72.3

Standard deviations, s₁ = 10.3

In case of second sample, sample size, n₂ = 12

Sample mean, [tex] \bar X_2[/tex] = 69.0

Standard deviations, s₂ = 8.9

Level of significance = 2.5% = 0.25

Consider the null and alternative hypothesis for the test hypothesis are defined as [tex]H_0 : μ_1 =μ_2[/tex]

[tex]H_a : μ_1 >μ_2[/tex]

The test statistic : using t-test formula

[tex]t = \frac{ \bar X_1 - \bar X_2}{\sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2}}}[/tex]

[tex]= \frac{72.3- 69}{ \sqrt{ \frac {10.3^2}{16} + \frac{8.9^2}{12}}}[/tex]

= 0.91

Degree of freedom, df = n1 + n2 - 2

= 16 + 12 -2 = 26

Using the t-distribution table, the critical value for t(0.025, df = 26) is equals to the 2.06. Now, the observed t-value = 0.91 is less than 2.06 ( standard t value), so, we do not reject H₀ . Hence, no evidence to support the researcher claim.

The value of the functions are;

f(-4) = 1/16

f(-3) = 1/8

f(-2) = 1/4

f(-1) = 1/2

f(0) = 1

How to determine the value

It is important to note that functions are described as equations or expressions that shows the relationship between two variables.

From the information given, we have that;

The function, f(x) = 2ˣ

To determine the value of f(x) for -4, we have to substitute the value

f(x) = 2⁻⁴

find the value

f(-4) = 1/2⁴ = 1/16

For the value of f(-3)

f(-3) =2⁻³

find the value

f(-3) = 1/2³ = 1/8

For the value of -2

f(-2) = 2⁻²

f(-2) = 1/2² = 1/4

For the value of -1

f(-1) = 2⁻¹

f(-1) = 1/2¹ = 1/2

For the value of 0

f(0) = 2⁰

f(0) = 1
