How to define a linear function?

The slope-intercept definition of a linear function is presented as follows:

y = mx + b.

In which:

The slope m represents the increase of y per each unit of x.The  intercept b represents the value of y when x = 0.

The parameters for this problem are given as follows:

m = 2, as each day, the number of goals increased by two.b = 10, as on the first day, he managed to kick 12 goals, hence on the day zero, the amount was of 12 - 2 = 10.

Hence the function giving the number of goals on day x is given as follows:

y = 2x + 10.

The number of days for him to score 100 goals is then obtained as follows:

100 = 2x + 10

2x = 90

x = 90/2

x = 45 days.

a) The average baggage-related revenue per passenger is: $ to the nearest cent)

b) The standard deviation of baggage-related revenue is: $ the nearest cent)

c) About how much revenue should the airline expect for a flight of 130 passengers? $ (please round to the nearest dollar)

Answers

The average baggage-related revenue per passenger is $29.80, using the variance the standard deviation of the baggage-related revenue is $27.35 and  the airline should expect about $3874 in revenue from baggage fees for a flight of 130 passengers (rounded to the nearest dollar).

What is the average baggage-related revenue per passenger

a) To find the average baggage-related revenue per passenger, we need to calculate the expected value of the baggage fees. Let X be the random variable that represents the number of checked bags per passenger. Then the expected value of the baggage fees per passenger is:

E[Baggage Fees] = E[20X + 40(max(0, X-1))]

= 20E[X] + 40E[max(0, X-1)]

= 20(0.31 + 0.14(2)) + 40(0.14 + 0.31)

= 29.80

Therefore, the average baggage-related revenue per passenger is $29.80

b) To find the standard deviation of the baggage-related revenue, we can use the formula for the variance:

Var[Baggage Fees] = E[(Baggage Fees - E[Baggage Fees])^2]

= E[(20X + 40(max(0, X-1)) - 29.80)^2]

= E[(20X - 40(max(0, X-1)))^2]

= E[400X^2 - 1600X(max(0, X-1)) + 1600(max(0, X-1))^2]

= 400E[X^2] - 1600E[X(max(0, X-1))] + 1600E[(max(0, X-1))^2]

To calculate these expected values, we can use the fact that:

E[X^2] = Var[X] + (E[X])^2

E[X(max(0, X-1))] = E[X^2] - E[X]

E[(max(0, X-1))^2] = Var[X] + (E[X])^2 - 2E[X] + 1/4

Plugging in the values, we get:

Var[Baggage Fees] = 400(0.31 + 0.14(4)) - 1600(0.31 + 0.14) + 1600(0.31 + 0.14 + 1/4)

= 748

Therefore, the standard deviation of the baggage-related revenue is $27.35 (rounded to the nearest cent).

c) For a flight of 130 passengers, the total revenue from baggage fees can be found by multiplying the average baggage-related revenue per passenger by the number of passengers:

Total revenue = 130($29.80)

= $3874

Therefore, the airline should expect about $3874 in revenue from baggage fees for a flight of 130 passengers (rounded to the nearest dollar).

a = _____
b = _____
The theorem that tells us that the solution must be in the interval [n, n+1] is that _____ (you must write out the full name, correctly spelled).

Answers

Answer:

Step-by-step explanation:

To find an integer n so that the interval of the form [n, n+1] contains the solution to the equation x^2 + 1/x = 1, we can first rewrite the equation as x^3 - x^2 + 1 = 0.

Next, we can use the Intermediate Value Theorem to find such an n. Since f(x) = x^3 - x^2 + 1 is a continuous function, if we can find two values of x, a and b, such that f(a) and f(b) have opposite signs, then there must exist a value of x between a and b for which f(x) = 0.

(a) Evaluating f(n) and f(n+1), we have:

f(n) = n^3 - n^2 + 1

f(n+1) = (n+1)^3 - (n+1)^2 + 1

(b) Since f(x) is a polynomial, it is continuous for all x, and so the largest possible interval on which f(x) is continuous is (-∞, ∞).

Thus, we want to find values a and b such that f(a) and f(b) have opposite signs. We can plot the function to get an idea of where the roots might be

   |    ./                          \

   |---------------------------------

        a                           b

From the graph, it appears that there is a root between 0 and 1, and another root between -1 and 0. We can use this information to choose a and b. Since we want the largest possible interval, we can take a = -1 and b = 1, so that the interval is (-∞, ∞).

Thus, the integer n such that [n, n+1] contains a root of x^2 + 1/x = 1 is given by n = 0.

The theorem that tells us that the solution must be in the interval [n, n+1] is the Intermediate Value Theorem.

Final answer:

The integer 'n' that fits the solution of the equation x^2 + 1/x = 1 within the interval [n, n+1] is 0. Using n=0 for the function f(x) = x^2 + 1/x - 1 it is undefined, but for n+1, it equals 1. The function f is continuous for all x ≠ 0 which is represented by the interval (-∞, 0) ∪ (0, ∞). This conclusion is established by the Intermediate Value Theorem.

Explanation:

The task involves solving the equation x2 + 1/x = 1 to find an integer 'n' such that the solution fits within the interval [n, n+1]. For this equation, rearranging to x2 - x + 1 = 0, we can use the quadratic formula to find x = (1±√(1-4))/2. This gives us two solutions x = 0.5 and x = -0.5.

However, only x=0.5 is found in the interval [0, 1], where n = 0.

For the function f(x) = x2 + 1/x - 1, at n = 0, the function is undefined. However, for f(n+1) it yields a value of 1.

The function f is continuous everywhere on its domain and the function is defined for all x ≠ 0, hence the function is continuous on the interval (-∞, 0) ∪ (0, ∞).

The theorem that ensures the solution is within the interval [n, n+1] is known as the Intermediate Value Theorem.

The interior angles of the triangle are in terms of t=15.

what are interior angles ?

In a polygon, an interior angle is an angle formed by two adjacent sides of the polygon inside the polygon. For example, in a triangle, the interior angles are the angles formed by the three sides of the triangle inside the triangle.

The formula for the sum of the interior angles of a polygon with n sides is:

(n-2) x 180 degrees

In other words, to find the sum of the interior angles of a polygon, you take the number of sides, subtract 2, and then multiply the result by 180 degrees.

For example, a triangle has 3 sides, so the sum of its interior angles is:

(3-2) x 180 = 1 x 180 = 180 degrees



Given by the question:
The sum of the interior angles of a triangle is 180 degrees. Therefore:

w + x + y = 180

(5t + 3) + (3t + 7) + 50 = 180

8t + 60 = 180

8t = 120

t = 15

Answers

It would take approximately 6.5 years for an investment to double at a simple interest rate of 11%.

According to given information :

To find the number of years necessary for an investment to double at a simple interest rate of 11%, we can use the following formula:

n = 72 / r

where n is the number of years required for the investment to double, and r is the interest rate.

Plugging in the values, we get:

n = 72 / 11

n ≈ 6.5 years (rounded to the nearest tenth)

Therefore, it would take approximately 6.5 years for an investment to double at a simple interest rate of 11%.

What is simple interest ?

Simple interest is a type of interest that is calculated on the principal amount of a loan or investment. It is a fixed percentage of the original amount borrowed or invested, and it is not compounded over time.

The formula for calculating simple interest is:

I = P * r * t

where I is the interest, P is the principal amount, r is the interest rate, and t is the time period.

For example, if you borrow $1,000 for two years at a simple interest rate of 5%, the interest you would pay is calculated as follows:

I = 1,000 * 0.05 * 2

I = $100

So, you would have to pay back the $1,000 principal plus $100 in interest, for a total of $1,100.

Simple interest is commonly used in short-term loans or investments, and it is usually easier to calculate and understand than compound interest, which takes into account the effect of earning interest on previously earned interest.

The height of the flagpole based on the information is 23 feet.

How to calculate the height

Let's start by converting the height of the person's shadow to feet, since the length of the flagpole's shadow is given in feet. There are 12 inches in a foot, so 54 inches is 54/12 = 4.5 feet.

Now we can set up a proportion to solve for the height of the flagpole:

(person's height) / (person's shadow length) = (flagpole height) / (flagpole shadow length)

Plugging in the values we know, we get:

5.75 / 4.5 = x / 18

5.75 * 18 = 4.5 * x

103.5 = 4.5x

Dividing both sides by 4.5, we get:

x = 103.5 / 4.5

x = 23

Answers

The standard error tells us how much we can expect the sample proportion to vary from the true proportion in repeated samples of the same size. Option (d) correctly states that "In samples of size 100 from this school, the sample proportion of students who bring a reusable water bottle from home typically varies by about 0.048 from the true proportion." This means that if we were to take many samples of 100 students from the same school and calculate the proportion of students who bring a reusable water bottle from home in each sample, about 95% of the sample proportions would fall within +/-0.048 of the true proportion.

What is the best interpretation of the standard error

The correct option is (d) "In samples of size 100 from this school, the sample proportion of students who bring a reusable water bottle from home typically varies by about 0.048 from the true proportion."

The standard error of the sample proportion can be calculated using the formula:

SE = √[p*(1-p) / n]

where p is the sample proportion and n is the sample size.

In this case, the sample proportion is 37/100 = 0.37 and the sample size is 100. Plugging in these values, we get:

What is the probability mass function?

A probability mass function (PMF) is a mathematical function that describes the probability of each possible value of a discrete random variable. In simpler terms, the PMF gives the likelihood of a specific outcome occurring when you randomly select an item from a finite set of possible outcomes.

The PMF assigns a probability to each outcome, such that the sum of all probabilities equals 1. The PMF is often presented in a table or a graph to show the probabilities associated with each possible value of the random variable.

The given probability mass function (pmf) for the number of batches ordered by a randomly chosen customer, X, is:

X P(X)

0 0.3

1 0.5

2 0.1

3 0.1

To calculate the expected value of X, we use the formula:

E(X) = Σ [x * P(X=x)]

E(X) = (0 * 0.3) + (1 * 0.5) + (2 * 0.1) + (3 * 0.1)

E(X) = 0 + 0.5 + 0.2 + 0.3

E(X) = 1

To calculate the variance of X, we first need to calculate the squared values of X:

0² = 0

1²  = 1

2² = 4

3² = 9

Then, we use the formula:

Var(X) = E(X²) - [E(X)]²

E(X²) = Σ [x² * P(X=x)]

E(X²) = (0² * 0.3) + (1² * 0.5) + (2² * 0.1) + (3² * 0.1)

E(X²) = 0 + 0.5 + 0.4 + 0.9

E(X²) = 1.8

Var(X) = E(X²) - [E(X)]²

Var(X) = 1.8 - 1²

Var(X) = 0.8 batches²

The expected number of pounds left after the next customer's order is shipped can be calculated as:

E(Weight left) = 100 - 8X

where X is the number of batches ordered by the next customer.

Using the formula for the expected value of X that we found earlier, we can write:

E(Weight left) = 100 - 8E(X)

E(Weight left) = 100 - 8(1)

E(Weight left) = 92 lb

To calculate the variance of the number of pounds left, we first need to find the variance of X, which we already calculated as 0.8 batches² Then, we use the formula for the variance of a linear function of a random variable:

Var(aX + b) = a² * Var(X)

where a = -8 (the negative sign indicates that the weight left decreases as X increases) and b = 100.

Var(Weight left) = (-8)² * Var(X)

Var(Weight left) = 64 * 0.8

Var(Weight left) = 51.2 lb^2

Therefore, the expected weight left after the next customer's order is shipped is 92 pounds, and the variance of the weight left is 51.2 pounds squared.

Given the following data, find the weight that represents the 40th percentile.

Answers

The smallest number in our sample of 11 numbers that is greater than or equal to 40% of the numbers.

what is percentage ?

In arithmetic, a percentage is a ratio or ratio that is presented as a part of 100. Usually, the acronyms "pct.," "pct," and "pc" are also utilized. Yet it is broadly classified into the following by the percent sign, "%." The % sum has no dimensions. Rates are essentially fractions when the sum is 100. Use the percent sign (%) to indicate that a number seems to be a percentage by placing it next to it. For illustrate, you score a 75% if you properly answer 75 out of 100 respondents on a test (75/100). Divide the money by total and multiply it by 100 to calculate percentages. The formula for calculating the percentage is (value/total) x 100%.

given

The 40th percentile's ordinal rank is equal to (40/100) X 10 (or 4).

50 is the 40th percentile and the following rank is 5 with 50 as the data value.

We observe that 50 is greater than 10, 20, 30, or 40% of the data,

On a coordinate plane, a dashed straight line has a positive slope and goes through (negative 1, negative 1) and (0, 1). Everything to the left of the line is shaded.
Which linear inequality is represented by the graph?

Group of answer choices

y > 2x + 2

y ≥ One-halfx + 1

y > 2x + 1

y ≥ One-halfx + 2

Answers

The correct linear inequality would be y > 2x + 1.

Option (A) is correct.

What is linear inequality?

A linear inequality is an inequality that can be written in the form of a linear equation with an inequality symbol, such as < (less than), > (greater than), ≤ (less than or equal to), or ≥ (greater than or equal to).

We can see that the line passes through the points (-1, -1) and (0, 1), and has a positive slope. The equation of the line can be found using the point-slope form:

y - y1 = m(x - x1), where m is the slope and (x1, y1) is one of the points on the line.

Using the point (-1, -1) and the slope 2, we get:

y - (-1) = 2(x - (-1))

y + 1 = 2x + 2

y = 2x + 1

Since the line is dashed, the inequality is not inclusive of the points on the line. Therefore, we use the inequality symbol > rather than ≥.

so the linear inequality would be  y > 2x + 1.

Therefore, the correct linear inequality would be y > 2x + 1.

Option (A) is correct.

Answers

Answer: When y=1, x=[tex]\frac{1}{2}[/tex]

It will be a point with the coordinates ([tex]\frac{1}{2}[/tex], 1)

Step-by-step explanation:

- Start plotting points from the y-intercept, in this case, -1.

- Since the function is written in the form y=mx+b, where the slope is b which is in this case 4. Meaning to say that from the y-intercept -1 you have to go 4 units up and 1 unit right.

- Continue plotting 2 or 3 points, then connect them with a straight line.

- For the value of x when y=1, we can substitute y with 1 and solve the equation for x.

1=4x-1  (Add 1 to both sides)

2=4x  (Divide by 4)

[tex]\frac{1}{2}[/tex]=x Write the solution.

Chuck works at the BuyMore where people can bring in broken computers. When a customer enters the store there is a good chance he will not be paid anything from helping them. But sometimes there is a chance he will be paid to work on their computer. The probability of each amount from a random customer is given in the following table: Job payment Probaiblity $8 0.42 $120 0.08 $300 0.05 $1,500 0.02 When the next person walks into the BuyMore, how much money can Chuck expect to get from them on average? Answer to two decimals $ 57.96 What is the probability he will get less than $283 from a random customer? Answer to four decimals What is the standard deviation for the payments from the customers? Answer to two decimals What is the median job payment amount? Answer to two decimals

Answers

The probability he will get less than $283 from a random customer is 0.93. 2. The standard deviation for the payments from the customers is 50678.88. 3. The median job payment amount is 120.

What is standard deviation?

The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed over a wider range, a low standard deviation suggests that the values tend to be close to the mean (also known as the anticipated value) of the collection.

The probability of 0 is given as:

p(0) = 1 - (0.42 + 0.08 + 0.05 + 0.02) = 0.43

1. The probability he will get less than $283 from a random customer:

p(x < 283) = p(0) + p(8) + p(120)

= 0.43 + 0.42 + 0.08

= 0.93

2. The standard deviation for the payments from the customers is:

E(x²) = ∑x²p(x) = (0)²(0.43) + (8)²(0.42) + (120)²(0.008) + (300)²(0.05) + (1500)²0.02

= 50678.88

this is a stringing arguments together

1. If Martin shot the sheriff, then he shot first.
2. If Martin didn't use his best pistol, he didn't shoot first.
3. So if Martin didn't use his best pistol, he didn't shoot the sheriff.

Answers

This is a valid example of stringing arguments together using conditional statements.

How to analyze the statement

The first statement establishes a conditional relationship between Martin shooting the sheriff and Martin shooting first.

The second statement also establishes a conditional relationship, but this time between Martin using his best pistol and Martin shooting first.

By combining the two conditional statements, we can conclude that if Martin didn't use his best pistol, then he didn't shoot first.

This follows from the fact that not using his best pistol would mean Martin didn't shoot first (according to statement 2), and if he didn't shoot first, then he couldn't have shot the sheriff (according to statement 1).

Therefore, the conclusion of the argument, which is that if Martin didn't use his best pistol, then he didn't shoot the sheriff, follows logically from the two conditional statements.
