Easy way

Step-by-step explanation:

Answer:

I say yes because when u solve it and flip the ( )'s, you get the same answer.

Step-by-step explanation:

Work:

(4/3 + 2/3) + 2

6/3 + 2

2 + 2

= 4

4/3 + (2/3 + 2)

4/3 + 8/3

12/3

= 4

Hope this helps!!

50 POINTS .....................

The option (C) Mus. Apt. = -22.26 + 0.4925(IQ score) is correct because the value of slope is 0.4925 and y-intercept is -22.26.

<h3>What is the line of best fit?</h3>

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2}

\rm c = \dfrac{\sum y -m \sum x}{n}

We have data shown in the picture.

Let's suppose the regression line is:

y = mx + c

Where m is the slope of the regression line and c is the y-intercept of the line.

We can calculate the value of m and c by using the formula.

After calculating, we get:

m = 0.4925

c = -22.26

Mus. Apt. = 0.49253(IQ score) - 22.26

or

Mus. Apt. = -22.26 + 0.4925(IQ score)

Thus, the option (C) Mus. Apt. = -22.26 + 0.4925(IQ score) is correct because the value of slope is 0.4925 and y-intercept is -22.26.
