I can't plot it for you, but the slope will be the y/x or the rise/run.

You can find the slope by using 2 points of the line and subtracting the (y1-y2)/(x2-x1)

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.

What 5.00 times 0.75 equal
xeze [42]
We know that 75=5*5*3 so
5*5*3 times 5=125*3=375 then move the decimal place two places to the left (divide by 100) and get 3.75

or you could note that 0.75=3/4 so
3/4 times 5=
15/4
simplified=3 and 3/4

Can someone please help me solve this?
Akimi4 [234]
A. This is the original equation: 2x + 3 - 1 = x + 5

b. 2x + 2 = x + 5 ← combined like terms on left side 
    2x + 2 - 2 = x + 5 - 2 ← used inverse operation to collect constants on right side
    2x = x + 3 ←simplified each side
    2x - x = x - x + 3 ←used inverse operation to collect variable terms on left side
    x = 3 ← simplified each side 
answer x = 3

c. 2(3) + 3 - 1 = 3 + 5
     6 + 3 - 1 = 8
       9  - 1 = 8
        8 = 8

Help plese.........ooj
Tatiana [17]
The answer is 6. You can find slope by using the slope formula: M= y1 - y2 / x1 - x2. In this case you can choose any two points from the table. I chose the second two points. the equation would then be (7-1) / (2-1). It would then be 6/1 or 6.
Hope this helped(:
