Answer:

To tell if a polynomial is constant, linear, quadratic, cubic or quartic, you must first look at the highest power of the variable in the polynomial. If the highest power is 0, then the polynomial is a constant. If the highest power is 1, then it is a linear polynomial. If the highest power is 2, then it is a quadratic. If the highest power is 3, then it is a cubic and finally, if the highest power of the variable is 4, then the polynomial is a quartic.

Answer:

Surface area = 408.2cm²

Volume = 628cm²

Step-by-step explanation:

r = radius

h = height

Surface Area

A = 2xπxrxh+2xπxr²

A = 2 x 3.14 x 5 x 8 + 2 x 3.14 x 25

A = 251.2 + 157

A = 408.2cm²

Volume

V = πr²h

V = 3.14 x 5 x 5 x 8

V = 628cm²

The length of side a is approximately 6.0 in the triangle. The correct option is (b) 6.0.

To find the length of side a in triangle ABC, we can use the Law of Sines.

The Law of Sines states that the ratio of a side length to the sine of its opposite angle is constant for all sides of a triangle.

In this case, we have:

a/sin(A) = b/sin(B) = c/sin(C)

Given that angle A has a measure of 29°, we can substitute the known values:

a/sin(29°) = 13.5/sin(B) = 8.9/sin(C)

Solving for side a, we have:

a = sin(29°) × 13.5 / sin(B)

To find sin(B), we can use the fact that the sum of the angles in a triangle is 180°:

B = 180° - A - C = 180° - 29° - 90° (since angle C is 90° in a right triangle)

B = 61°

Now we can calculate side a:

a = sin(29°) × 13.5 / sin(61°)

a ≈ 6.0

Therefore, the length of side a is approximately 6.0. The correct option is (b) 6.0.

Answer:

$9.25

Step-by-step explanation:

One box of popcorn costs $2.65 while the total cost of three boxes of popcorn and a fountain drink is $9.70.

We have,

We are given that the cost C of buying three boxes of popcorn and a fountain drink is represented by the equation C = 3x + 1.75.

Where x is the number of popcorn.

Now,

We want to find the cost of one box of popcorn when the cost is $9.70.

Let's first substitute C = 9.70 into the equation:

9.70 = 3x + 1.75

Next, we'll isolate x by subtracting 1.75 from both sides:

9.70 - 1.75 = 3x

7.95 = 3x

Finally, we'll solve for x by dividing both sides by 3:

x = 7.95/3 = 2.65

Therefore,

One box of popcorn costs $2.65 while the total cost of three boxes of popcorn and a fountain drink is $9.70.

The equation of the line in Slope-intercept form is y = -3x - 3.

The equation of the line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept, we need to solve for y.

Starting with the given equation:

9x + 3y = -9

We can isolate y by subtracting 9x from both sides:

3y = -9x - 9

Now we can simplify the equation by dividing both sides by 3:

y = (-9/3)x - 3

Simplifying the fraction, we get:

y = -3x - 3

Therefore, the equation of the line in slope-intercept form is y = -3x - 3.

The expression 1.05h correctly represents the total amount Sylvia will pay for the hat if it costs h dollars.

Sylvia knows that the price of the hat will increase by 5% when she pays sales tax. Let's break down the expressions to understand them better.

Expression 1: h + 0.05h

In this expression, h represents the cost of the hat. Adding 0.05h to h accounts for a 5% increase. However, this expression does not accurately represent the total amount Sylvia will pay because it only considers the increase due to sales tax, not the original cost of the hat.

Expression 2: 1.05h

In this expression, 1.05 represents the total cost multiplier, which includes the original cost of the hat and the 5% increase. Multiplying h by 1.05 accounts for both the original cost and the sales tax increase. This expression correctly calculates the total amount Sylvia will pay for the hat.

Therefore, the expression 1.05h is the correct representation of the total amount Sylvia will pay for the hat if it costs h dollars.

The zeros of the function F(x) = -(x+6)^2 - 49 are -6 - 7i and -6 + 7i.

To find the zeros of the function F(x) = -(x+6)^2 - 49, we need to find the values of x when F(x) = 0.
Step 1: Set the function equal to 0.
0 = -(x+6)^2 - 49
Step 2: Isolate the squared term.
49 = -(x+6)^2
Step 3: Divide both sides by -1 to remove the negative sign.
-49 = (x+6)^2

Answer:

The volume of the recycling bin when the length is doubled is 3,600 cubic feet.

To find the volume of the recycling bin when the length is doubled, we first need to determine the original volume of the bin.

The formula for the volume of a rectangular prism is V = lwh, where l is the length, w is the width, and h is the height.

In this case, the length is 15 ft, the width is 12 ft, and the height is 10 ft. So the original volume of the recycling bin is:

V = lwh = 15 ft × 12 ft × 10 ft = 1,800 cubic feet

To find the volume when the length is doubled, we simply need to multiply the original length by 2, and then calculate the new volume using the same formula:

New length = 15 ft × 2 = 30 ft

New volume = lwh = 30 ft × 12 ft × 10 ft = 3,600 cubic feet

To make the game fair, we need to ensure that the probability of drawing a card with a star is the same as the probability of drawing a card without a star.

Currently, there are 4 cards with stars and 6 cards without stars, which means the probability of drawing a star is 4/10 or 2/5, while the probability of drawing a card without a star is 6/10 or 3/5.

To make the game fair, we need to adjust the number of cards with stars and without stars so that the probabilities are equal.

Option A is not correct because the game is not currently fair.

Option B is not correct because adding 2 cards with stars will increase the probability of drawing a star to 6/12 or 1/2, which is not equal to the probability of drawing a card without a star.

Option C is also not correct because adding a star to 1 of the blank cards will still result in a probability of drawing a star that is not equal to the probability of drawing a card without a star.

Therefore, the correct answer is option D: take away 2 blank cards. If we remove 2 blank cards, we are left with 4 cards with stars and 4 cards without stars.

Answer:

The correct answer is: A. If many different samples of size 250 were selected and, based on each sample, a confidence interval were constructed, in the long run 99% of the confidence intervals would contain the true value of p.

Step-by-step explanation:

A confidence interval is a range of values that is likely to contain the true value of a population parameter. In this case, the population parameter is the proportion of voters who favor a tax on e-commerce. The confidence interval is constructed from a sample of voters, and it is based on the assumption that the sample is representative of the population.

The 99% confidence interval means that if we were to take many different samples of size 250 and construct a confidence interval for each sample, 99% of the confidence intervals would contain the true value of the population proportion. This does not mean that there is a 99% chance that the true value of the population proportion lies between 0.113 and 0.171. It means that if we were to take many different samples of size 250 and construct a confidence interval for each sample, 99% of the confidence intervals would contain the true value of the population proportion.

The other answer choices are incorrect because they do not correctly interpret the meaning of a confidence interval.

To find the test statistic for a test to show that the population mean height of the school district is lower than 59 inches, we can perform a one-sample t-test.

The test statistic is calculated using the sample mean, sample standard deviation, sample size, and the hypothesized population mean.

Given the sample heights of the 11 fifth-grade boy students: 59.0, 57.2, 57.1, 58.0, 57.0, 50.1, 52.3, 55.6, 57.8, 53.9, 57.8, we can calculate the sample mean () and sample standard deviation (s).

= (59.0 + 57.2 + 57.1 + 58.0 + 57.0 + 50.1 + 52.3 + 55.6 + 57.8 + 53.9 + 57.8) / 11

Next, calculate the sample standard deviation:

s = sqrt(((59.0 - )^2 + (57.2 - )^2 + ... + (57.8 - )^2) / (11 - 1))

Once you have the sample mean and sample standard deviation, you can calculate the test statistic (t):

t = ( - μ) / (s / sqrt(n))

where μ is the hypothesized population mean (in this case, 59 inches), and n is the sample size (11).

The coordinates of the midpoint M of segment JK are (-0. 3). The distance between the endpoints of JK is sqrt(104) or approximately 10.198.

To find the coordinates of the midpoint M of segment JK, we can use the midpoint formula, which states that the x-coordinate of the midpoint is the average of the x-coordinates of the endpoints and the y-coordinate of the midpoint is the average of the y-coordinates of the endpoints. So, for segment JK with endpoints J(3, -6) and K(-3, 2), the x-coordinate of the midpoint is (-3+3)/2 = 0 and the y-coordinate of the midpoint is (-6+2)/2 = -2. Therefore, the coordinates of the midpoint M are (0, -2).

To find the distance between the endpoints of JK, we can use the distance formula, which states that the distance between two points with coordinates (x1, y1) and (x2, y2) is given by the square root of [(x2-x1)^2 + (y2-y1)^2]. So for segment JK with endpoints J(3, -6) and K(-3, 2), the distance is sqrt[(-3-3)^2 + (2-(-6))^2] = sqrt[36 + 64] = sqrt(100) = 10. Therefore, the distance between the endpoints of JK is approximately 10.198.

The unconditional expectation of y (E(y)) equals β0 + (β1 * E(x)), derived using the Law of Iterated Expectations.

To simplify the expression for the unconditional expectation E(y), we can apply the properties of expected value and the Law of Iterated Expectations. The Law of Iterated Expectations states that the unconditional expectation of a conditional expectation is equal to the unconditional expectation itself.

Starting with the expression for E(y):

E(y) = E(β0 + β1x + u)

We can break down this expression using the linearity of expectation:

E(y) = E(β0) + E(β1x) + E(u)

Since β0 and β1 are constants, their expected values are equal to themselves:

E(y) = β0 + β1E(x) + E(u)

Now, since u is the error term and it is assumed to have a mean of zero (E(u) = 0), the expression simplifies to:

E(y) = β0 + β1E(x)

Therefore, we can conclude that the unconditional expectation of y (E(y)) is equal to the constant term β0 plus the product of the slope coefficient β1 and the unconditional expectation of x (E(x)). This result follows from the Law of Iterated Expectations, which allows us to simplify the expression by considering the expected values of the individual terms separately.

Answer:

x = 19

Step-by-step explanation:

Let's use the following variables:

Let x be the number of coach seats sold.

Let y be the number of first-class seats sold.

We know that there are 29 seats in total, so:

x + y = 29

We also know that the total amount collected for the flight was $21,900, so:

600x + 1050y = 21,900

We can solve this system of equations by substitution or elimination. Let's use elimination.

Multiplying the first equation by 600, we get:

600x + 600y = 17400

Subtracting this equation from the second equation, we get:

450y = 4500

Dividing both sides by 450, we get:

y = 10

Substituting this value into the first equation, we get:

x + 10 = 29

x = 19

Therefore, the airline sold 19 coach seats and 10 first-class seats.
