An average of 3 people are stepping onto the roller coaster per minute at peak time. The answer is option B) 6.

To determine the number of people who are stepping onto the roller coaster per minute at peak time, you need to divide the number of people on the roller coaster by the duration of the ride. Hence, the correct option is B) 6.

To be more specific, this means that at peak time, an average of 3 people is getting on the ride per minute. This is how you calculate it:

Number of people per minute = Number of people on the roller coaster / Duration of the ride

Number of people on the roller coaster = 24

Duration of the ride = 8 minutes

Number of people per minute = 24 / 8 = 3

Therefore, an average of 3 people are stepping onto the roller coaster per minute at peak time. The answer is option B) 6.

There are 92,378 different assignments of pollsters to houses where two pollsters will canvas a neighborhood with 20 houses.

There are 20 houses to choose from for the first pollster, and then 19 houses remaining for the second pollster.

However, since the order in which the pollsters visit the houses does not matter, we need to divide by the number of ways of arranging the 10 houses that each pollster will visit evaluated using probability.

Therefore, the total number of different assignments of pollsters to houses is:

(20 choose 10) * (10 choose 10) / 2! = (184,756) * (1) / 2 = 92,378

So there are 92,378 different assignments of pollsters to houses.

The equivalent ratio to 4 to 6 is 2 to 3.

Student 1: 8 to 12, Student 2: 2 to 3,  Student 3: 10 to 15, Student 4: 40 to 60. The ratio of blue pens to black pens on a teacher's desk is 4 to 6. If we add 4 and 6, we get 10. This means that for every 10 pens, 4 of them are blue and 6 of them are black. We can write this ratio as 4:6 or as a fraction 4/10, which can be simplified to 2/5.To write an equivalent ratio, we need to multiply the numerator and the denominator of the original ratio by the same number. We can multiply both by 2, to get the equivalent ratio of 8:12 or simplify it to 2:3, which is Student 2's answer. Therefore, the equivalent ratio to 4 to 6 is 2 to 3.

To find the vector v, we can perform the vector operation v = u + 2w, where u = (-3, 2) and w = (-2, -3). The resulting vector v can be obtained by adding twice the components of w to the components of u. Geometrically, the vector operation of adding u and 2w corresponds to translating u in the direction of w by twice the length of w.

Given the vectors u = (-3, 2) and w = (-2, -3), we can perform the vector operation v = u + 2w by adding twice the components of w to the components of u.

v = (-3, 2) + 2(-2, -3)

 = (-3, 2) + (-4, -6)

 = (-7, -4)

So, the vector v is (-7, -4).

Geometrically, the vector addition u + 2w corresponds to translating the vector u in the direction of vector w by twice the length of w. In this case, starting from the point representing u, we move twice the length of w in the direction of w to obtain the point representing the vector v.

Tukey's procedure to investigate significant differences between brands is x3. and x5.

x4. and x5.

To use Tukey's procedure to investigate significant differences between brands, we need to calculate the value of W and compare it with the critical value from the Studentized Range Distribution.

The formula for W is:

W = q(α, 5, 15) * √(MSE/4)

where q(α, 5, 15) is the critical value from the Studentized Range Distribution with α = 0.05, k = 5 (number of brands), and df = 15 (total degrees of freedom). Using a table or calculator, we find:

q(0.05, 5, 15) = 3.07

Plugging in the given values, we get:

W = 3.07 * √(450.8/4) ≈ 17.99

Since the computed value of F was found to be significant at level α = 0.05, we can conclude that there are significant differences between at least some of the brands. To determine which brands differ significantly from one another, we can use the formula:

|xi. - xj.| ≥ W / √(2MSE/4)

where xi. and xj. are the sample averages for any two brands i and j. If this inequality is satisfied, then we can say that the two brands differ significantly from one another.

Calculating the absolute differences between all pairs of sample averages and comparing them with the right-hand side of the inequality above, we get:

|462.0 - 502.8| = 40.8 ≥ 8.99 → Significant

|462.0 - 427.5| = 34.5 < 8.99 → Not significant

|462.0 - 469.3| = 7.3 < 8.99 → Not significant

|462.0 - 532.1| = 70.1 ≥ 8.99 → Significant

|502.8 - 427.5| = 75.3 ≥ 8.99 → Significant

|502.8 - 469.3| = 33.5 < 8.99 → Not significant

|502.8 - 532.1| = 29.3 < 8.99 → Not significant

|427.5 - 469.3| = 41.8 ≥ 8.99 → Significant

|427.5 - 532.1| = 104.6 ≥ 8.99 → Significant

|469.3 - 532.1| = 62.8 ≥ 8.99 → Significant

Using the critical value W, we can conclude that brands 1, 2, 4, and 5 differ significantly from one another. Therefore, the correct answer is:

x1. and x2.

x1. and x5.

The horizontal distance from the base of the skyscraper out to the ship would be 401.1 feet.

Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.

In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slanted side is called the hypotenuse.

Let d the horizontal distance from the base of the skyscraper out to the ship. Since the angle of depression is 67°, hence:

Angle = 90 - 67 = 23°

Using trigonometric ratio:

tan(23) = d/ 945

d = 401.1 feet

The horizontal distance from the base of the skyscraper out to the ship would be 401.1 feet.

After reflection over the x-axis the ordered pair is at (-4, 7).

When two different media come together at an interface, a wavefront might change direction so that it returns to the first medium, which is known as reflection.

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the x-axis is (x, -y).

The given expression is:

[9 4 [8 7 6 5] + 9 3]

The expression inside the brackets [8 7 6 5] is a 1x4 matrix. In order to add the matrix [8 7 6 5] to [9 4], we need to ensure that the dimensions match. Therefore, we can rewrite [9 4] as a 1x2 matrix by adding a zero in the third position. Thus, we have:

[9 4 0] + [8 7 6 5 9 3]

Now, the dimensions match, and we can add the corresponding elements:

The interpretation of the scatter plot is done, and yes, the correlation coefficient of r = -0.98 makes sense based on the interpretation of the scatterplot in part A.

Given data were gathered on how deep sharks dive from the surface of the water based on body weight and graphed on a scatterplot.

Part A: Interpret the scatterplot

The scatterplot is a visual representation of the relationship between two sets of data that are plotted against each other. It is used to identify trends in data, as well as potential outliers, or anomalies. Let's interpret the given scatter plot.

Association:

As the weight of the shark increases, the depth to which it dives decreases, which is a negative association.

Form:

The scatterplot shows a strong negative correlation.

Strength: The strength of the negative correlation is strong as the dots are tightly clustered and all fall near a straight line.

Outliers:

There are no outliers present in the data.

Part B:

The correlation coefficient of the data is r = -0.98. Does this correlation make sense based on the interpretation in part A? Explain

Yes, the correlation coefficient of r = -0.98 makes sense based on the interpretation of the scatterplot in part A. The scatterplot showed a strong negative correlation between the weight of the sharks and the depth to which they dive. A correlation coefficient of -0.98 is a strong negative correlation, which supports the scatterplot's visual representation of the data.

The coefficient measures the strength of the correlation between two variables. A coefficient of -1 indicates a perfect negative correlation, meaning that as one variable increases, the other decreases. A coefficient of 0 indicates no correlation, and a coefficient of 1 indicates a perfect positive correlation.

Therefore, r = -0.98 shows that there is a strong negative correlation between the two variables, which is supported by the scatterplot's visual representation of the data.
