Answer:

Step 2.

Step-by-step explanation:

When you have a coefficient on a side of the equation that you need to get rid of, you must divide by the number. For example, in the problem:

3(x+8)² = 75

Here, you need to divide both sides by '3' instead of multiplying, which was done instead. Then you get:

(x+8)² = 25.

Therefore, his mistake was made at Step 2.

Answer:

Not independent

Step-by-step explanation:

This problem involves independence criteria for conditional probabilities.

The two events will be independent if P(A/B)=P(A) or P(B/A)=P(B)

Let us assumes that event A is for student attending private college and B is for student graduating in four years.

So we are given the following probabilities

P(A)=0.20

P(B)=0.55

P(B/A)=0.79

As we can see that P(B/A)≠P(B) so the events A and B are not independent.

So based on the above results we can say that "attending a private college or university" is not independent of "graduating in four years". Thus the two events "attending a private college or university" and "graduating in four years" are dependent.

g100num [7]

Scores on one variable plotted against scores on a second variable.

The correct answer is (b)

Now, According to the question:

Let's know:

<u>A scatterplot shows:</u>

A scatterplot shows the relationship between two quantitative variables measured for the same individuals. The values of one variable appear on the horizontal axis, and the values of the other variable appear on the vertical axis. Each individual in the data appears as a point on the graph.

Hence, The correct answer is (b) i.e.,

Scores on one variable plotted against scores on a second variable.

Given,

In the question:

A scatterplot shows:

a. the average value of groups of data.

b. scores on one variable plotted against scores on a second variable.

c. the frequency with which values appear in the data

d. the proportion of data falling into different categories.
