Residual Plot A indicates that the linear model is not appropriate because the fanned pattern shows that the model's predicting power decreases as the values of the explanatory variable increases. Residual Plot B indicates that the linear model is appropriate because the scattered residuals suggest a linear relationship.

Residual Plot A shows a fanned pattern which indicates that the linear model is not appropriate. This means that the model's predicting power decreases as the values of the explanatory variable increases. This suggests that the relationship between the dependent and independent variables is not linear and a different model may be necessary. Residual Plot B, on the other hand, shows a scattered pattern which suggests that the linear model is appropriate. The scattered pattern indicates that the data points are randomly distributed, which is a sign of a linear relationship. This indicates that the linear model is an appropriate fit for the data.

The length of the altitude is 9 units.

To solve this problem, we can use the geometric relationship in a right triangle between the lengths of the altitude, the hypotenuse, and the segments it divides.

Let the length of the altitude be 'h'. According to the problem, the altitude divides the hypotenuse into segments of lengths 6 and 9. Let's denote the lengths of these segments as 'x' and 'y', respectively.

Using the properties of similar triangles, we can set up the following proportion:

h / x = y / (x + y)

Cross-multiplying the proportion:

h(x + y) = xy

Expanding:

hx + hy = xy

Rearranging the equation:

hx - xy = -hy

Factoring out 'h':

h(x - y) = -hy

Dividing both sides by (x - y):

h = -y

From the given information, we know that the lengths of the segments are 6 and 9. So, we substitute x = 6 and y = 9 into the equation:

h = -(9)

h = -9

The length of the altitude is 9 units.

Question

The altitude to the hypotenuse of a right triangle divides the hypotenuse into segments of lengths 6 and 9. What is the length of the altitude?

Answer:

x = 59°

y = 130°

Step-by-step explanation:

Find x:

Recall: the measure of an inscribed angle = ½(measure of intercepted arc), based in the inscribed angles theorem

Therefore,

x = ½(118°)

x = 59°

Find y:

y = 2(180 - (56 + x)) => inscribed angles theorem

Plug in the value of x

y = 2(180 - (56 + 59))

y = 2(180 - 115)

y = 2(65)

y = 130°

First, we have to recognize that if the current number of girls in the class is a 15% increase from last year, then this year's number is 115% of last year's number.  

With that, we can set up a proportion comparing last year to this year, in both percentages and numbers:

     \(\dfrac{100}{115} = \dfrac{x}{15}\)

Note that both numerators are last year's values and the denominators are this year's values.

If we multiply both sides by 15, we have that x ≈ 13.043478260869565.  Since we're dealing with whole people, we'd say that there were 13 girls in the class last year.

The maximum speed of the sprinter during the race is estimated to be approximately 12.72 meters per second.

To calculate the maximum speed of the sprinter during the race, we need to determine the average speed over the entire distance. The formula for average speed is distance divided by time. In this case, the distance covered by the sprinter is 200 meters, and the time taken to cover this distance is 20.32 seconds.

Average Speed = Distance / Time

Average Speed = 200 meters / 20.32 seconds

Average Speed ≈ 9.84 meters per second

So, the average speed of the sprinter during the race is approximately 9.84 meters per second.

However, to find the maximum speed, we need to consider that sprinters often accelerate during a race. The sprinter's time splits of 0-5-20.32 indicate that it took the sprinter 5 seconds to cover the initial 0 meters. This suggests that the sprinter was accelerating during this period.

To estimate the maximum speed, we can calculate the average speed for the remaining 195 meters (200 meters - 5 meters).

Average Speed = Distance / Time

Average Speed = 195 meters / (20.32 seconds - 5 seconds)

Average Speed ≈ 195 meters / 15.32 seconds

Average Speed ≈ 12.72 meters per second

Therefore, the maximum speed of the sprinter during the race is estimated to be approximately 12.72 meters per second. It's important to note that this is an estimate based on the given information, and actual maximum speeds achieved by athletes can vary based on various factors such as training, technique, and race conditions.

The probability that a randomly selected ball has a number less than 10 is \($\frac{9}{19}\).

As per the given data:

A bag contains 19 balls numbered 1 through 19.

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 and 19

The total number of outcomes is 19.

Here we have to determine the probability that a randomly selected ball has a number less than 10.

Numbers on the balls less than 10 are 1, 2, 3, 4, 5, 6, 7, 8, and 9.

A ball is randomly selected.

The favorable outcomes are 9.

The likelihood of every event depends on the overall number of positive outcomes as well as the number of favorable outcomes.

The formula for probability:

The number of favorable outcomes is divided by the total number of outcomes.

= \($\frac{9}{19}\)

Therefore the probability that a randomly selected ball has a number less than 10 is \($\frac{9}{19}\).

e) The sample of 30 students we surveyed suggests that the proportion of Honda drivers may be higher than 45%.

a) The null and alternative hypotheses are as follows: H₀: p = 0.45H₁: p ≠ 0.45

b) The appropriate test statistic is the z-score.

We will calculate it as follows: z = (phat - p) / sqrt(p * (1 - p) / n) where phat is the sample proportion, p is the hypothesized proportion, and n is the sample size. In this case, we have phat = 22/30 = 0.733, p = 0.45, and n = 30.

Substituting these values, we get: z = (0.733 - 0.45) / sqrt(0.45 * 0.55 / 30) = 2.08

c) To find the p-value, we need to calculate the area in the tails of the standard normal distribution beyond the absolute value of the z-score.

Using a table or calculator, we find that P(Z > 2.08) = 0.018. Since this is a two-tailed test, the p-value is 0.018 x 2 = 0.036

d) Since the p-value (0.036) is less than the level of significance (0.05), we reject the null hypothesis and conclude that there is evidence to suggest that the proportion of RWU students who drive a Honda is different than 45%.

e) This means that the report claiming that 45% of RWU students drive a Honda may not be accurate.

The rise is the vertical change. Here, that is shown as 3 m.

The run is the horizontal change. Here, that is shown as 36 m.

Then the slope is ...

To find the area of the given figure, we can divide it into two separate shapes, a rectangle and a triangle, and then add their areas together.

First, we can find the area of the rectangle by multiplying its length and width. From the diagram, we can see that the length of the rectangle is 12 cm and the width is 5 cm.

Area of rectangle = length x width

Area of rectangle = 12 cm x 5 cm

Area of rectangle = 60 cm^2

Next, we can find the area of the triangle by using the formula for the area of a triangle, which is:

Area of triangle = 1/2 x base x height

From the diagram, we can see that the base of the triangle is 5 cm and the height is 8 cm.

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 5 cm x 8 cm

Area of triangle = 20 cm^2

Finally, we can find the total area of the figure by adding the area of the rectangle and the area of the triangle:

Total area = area of rectangle + area of triangle

Total area = 60 cm^2 + 20 cm^2

Total area = 80 cm^2

Therefore, the area of the given figure is 80 square centimeters.

To find three consecutive integers such that four times the sum of all three is two times the product of the larger two, follow these steps:

1. Let the three consecutive integers be x, x+1, and x+2.
2. According to the problem, 4 times the sum of these integers is equal to 2 times the product of the larger two. So, we can write the equation: 4(x + (x+1) + (x+2)) = 2((x+1)(x+2)).
3. Simplify the equation: 4(3x + 3) = 2(x^2 + 3x + 2).
4. Expand the equation: 12x + 12 = 2x^2 + 6x + 4.
5. Move all terms to one side of the equation to form a quadratic equation: 2x^2 - 6x - 8 = 0.
6. Factor the equation: 2(x^2 - 3x - 4) = 0.
7. Solve the quadratic equation: (x-4)(x+1) = 0.
8. Find the integer solutions: x = 4 or x = -1.
