add that all up and you should get 82.13

Each of the residual plots indicates the appropriateness of the linear model that was fit to the data. The appropriate answer for residuals plot (a) is: the fanned pattern indicates that the linear model is not appropriate.

The model's predicting power decreases as the values of the explanatory variable increase.

A residual is the difference between the actual y value and the predicted y value, which is determined by the regression equation or linear model. A scatterplot of residuals is often used to evaluate the appropriateness of a linear model in a regression analysis, as well as to check for other things like non-linear relationships or non-constant variance.

Residuals scatterplots assist in detecting various types of patterns or lack of patterns that may be present in data. Patterns in a residual plot indicate that the linear model does not fit the data well, whereas the lack of pattern in a residual plot indicates that the linear model is appropriate.In this problem, the residual plot (a) has a fanned pattern. This means that the linear model is not appropriate. Furthermore, the model's predicting power decreases as the values of the explanatory variable increase. This means that the model may overestimate or underestimate the response variable as the values of the explanatory variable rise.

Therefore, we can conclude that the fanned pattern on residual plot (a) indicates that the linear model is not appropriate.

Answer: To find the unit rate that describes the number of gallons per dollar, we need to divide the number of gallons by the cost in dollars. In this case, we have:

Number of gallons = 5

Cost in dollars = $16.25

Dividing the number of gallons by the cost in dollars, we get:

Gallons per dollar = Number of gallons / Cost in dollars

= 5 / $16.25

= 0.3077...

Rounding to two decimal places, we get:

Gallons per dollar = 0.31

Therefore, the unit rate that describes the number of gallons per dollar is 0.31 gallons per dollar.

The measure of the diagonal of the square table is 15 * [tex]\sqrt{2}[/tex] feet (approximately 21.21 feet).

The diagonal of a square is the line segment that links two opposed corners of the square. The Pythagorean theorem asserts that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides.

In this case, the diagonal of the square is the hypotenuse of a right triangle with two legs of length 15ft each (since the sides of a square are equal in length). So, we can use the Pythagorean theorem as follows:

[tex]diagonal^2[/tex] = [tex]15^2 + 15^2[/tex]

[tex]diagonal^2[/tex] = 450

diagonal = [tex]\sqrt{450}[/tex]

Using a calculator or simplifying by factoring out perfect squares, we get:

diagonal = [tex]\sqrt{(225 * 2)}[/tex] = 15 * [tex]\sqrt{2}[/tex]

Therefore, the measure of the diagonal of the square table is 15 * [tex]\sqrt{2}[/tex] feet (approximately 21.21 feet).

The area of the dilated triangle is 45 squared meters

Dilation is a geometric transformation that involves resizing a shape while maintaining its shape and proportions. The scale factor is the ratio of the size of the image to the size of the original shape.

In this problem, we are given a triangle with an area of 5 cm², and we are asked to find the area of the dilated triangle when it is scaled up by a factor of 3. To find the area of the dilated triangle, we need to use the formula for the area of a triangle, which is 1/2 * base * height.

When a triangle is dilated by a scale factor of k, both its base and height are multiplied by k. This means that the area of the dilated triangle is k^2 times the area of the original triangle. In this case, the scale factor is 3, so the area of the dilated triangle is 3^2 times the area of the original triangle.

Therefore, the area of the dilated triangle is 9 times the area of the original triangle, which is 9 * 5 cm² = 45 cm².

When the bottom of the 6-foot ladder is 2 feet from the wall, the bottom is moving along the ground at 1 foot per second.

To find the rate at which the bottom of the ladder moves along the ground, we can use the Pythagorean theorem and related rates. Let x be the distance from the bottom of the ladder to the wall, and y be the height of the ladder on the wall. The Pythagorean theorem is x² + y² = 36.

Differentiating both sides with respect to time (t) gives 2x(dx/dt) + 2y(dy/dt) = 0. We are given that dy/dt = -2 ft/s, and we need to find dx/dt when x = 2 feet.

To find y, we can use the Pythagorean theorem: 2² + y² = 36, so y² = 32, and y = 4√2. Plugging these values into the differentiated equation, we get 2(2)(dx/dt) + 2(4√2)(-2) = 0. Solving for dx/dt, we find that dx/dt = 1 ft/s.

The value of x is 6m. Polygons can be regular or irregular, depending on whether all their sides and angles are congruent or not.

To find the value of x in the similar polygons shown in the figure, we can use the fact that corresponding sides of similar polygons are proportional. A polygon is a two-dimensional closed shape with three or more straight sides and angles. It is formed by connecting consecutive line segments, which are called sides, at their endpoints. The point where two sides of a figure meets is called a vertex. A polygon can have any number of sides, but it must have at least three. Polygons include triangles, quadrilaterals, pentagons, hexagons, and many more.

Since the polygons are similar so, the ratio of sides will be equal:

The percent increase in players from last year to this year = 20%

We know that the formula for the percentage change a quantity is :

(P) = [Final value - Initial value] / Initial value x 100

Here, a baseball team had 80 players show up for tryouts last year and this year 96 show up for tryouts.

initial number of players = 80

current number of players = 96

So, using above formula the percent increase in players is:

P = [(96 - 80) / (80)] x 100

P = (16 / 80) x 100

P = 0.20 x 100

P = 20%

Robyn has 4 important files saved on her computer.

To solve this problem, we can use a simple formula that relates the total space occupied by the files to the size of each file:

Total space occupied = Size of each file x Number of files

In this case, we know the total space occupied (84.6 megabytes) and the size of each file (21.15 megabytes), so we can rearrange the formula to solve for the number of files:

Number of files = Total space occupied ÷ Size of each file

Plugging in the values we know, we get:

Number of files = 84.6 megabytes ÷ 21.15 megabytes per file

Simplifying this expression gives us:

Number of files = 4

Therefore, Robyn has 4 important files saved on her computer.

It's important to note that this problem assumes that each file uses exactly 21.15 megabytes of memory. In reality, file sizes can vary depending on their content, so this may not always be the case. Additionally, it's worth noting that file size can be affected by various factors such as compression and encoding, so the actual size of a file on disk may differ from its theoretical size. Nonetheless, for the purposes of this problem, we can assume that each file uses exactly 21.15 megabytes of memory.

The expected winnings for a ticket buyer is $0.8036.

The given details are:

Grand prize = $9000

Second prize = $1300

Cost of each ticket = $3

Total tickets sold = 11200

Expected winnings are calculated by finding the expected value. Expected value is calculated by multiplying each outcome by its probability and then adding the products.

The total amount collected from selling 11200 tickets will be:

Total amount collected = 11200 × $3 = $33,600

Probability of winning grand prize = 1/11200

Probability of winning second prize = 1/11200

Probability of losing = 1 - (1/11200 + 1/11200) = 1 - 2/11200 = 11200/11200 - 2/11200 = 11198/11200

Expected value = probability of winning grand prize × grand prize + probability of winning second prize × second prize + probability of losing × zero

Expected value = (1/11200) × $9000 + (1/11200) × $1300 + (11198/11200) × 0 = $0.8036

The probability of having fifth tail occurring before the tenth head if a fair coin is flipped repeatedly is 0.377.

To solve this problem, we need to use the concept of negative binomial probability distribution.

The negative binomial probability distribution is a type of probability distribution that is used to describe the probability of k failures occurring before r successes in a sequence of independent and identical trials.

Let us consider the problem at hand.

We need to find the probability that the fifth tail occurs before the tenth head if a fair coin is flipped repeatedly.

Let X be the number of trials required to obtain the fifth tail. Then, X follows a negative binomial distribution with parameters r = 5 (number of successes we want) and p = 0.5 (the probability of obtaining a tail in a single flip).

The probability of obtaining the fifth tail on the kth trial is given by: P(X = k) = ᵏ-¹C₄(1 - p)ᵏ-ʳ *

where ᵏ-¹C₄ denotes the number of combinations of (k - 1) trials that yield 4 tails before the kth trial.

Since X should occur before the tenth head, k should be less than or equal to 9.

Therefore, we can calculate the required probability as follows:

P(X ≤ 9) = ∑P(X = k) for k = 5 to 9

= (⁴C₄*0.5⁵) + (⁵C₄*0.5⁶) + (⁶C₄*0.5⁷) + (⁷C₄*0.5⁸) + (⁸C₄*0.5⁹)

= (1*0.03125) + (5*0.015625) + (15*0.0078125) + (35*0.00390625) + (70*0.001953125)

= 0.376953125
