Answer:

0.43

Step-by-step explanation:

To calculate the relative frequency of any of the values in the frequency table, divide the value by the total (120)

For example, the relative frequency of boys who prefer math is:

43 ÷ 120 = 0.36

Reading from the frequency table, the total number of boys is 52. Therefore, the relative frequency for the total number of boys is:

52 ÷ 120 = 0.43

Chem deposited $115.00 in a savings account. Each week thereafter, he

Yanka [14]

Answer:

Part a) $y=35x+115$

Part b) $\$1,165$

Step-by-step explanation:

Part a)

Let

x -----> the number of weeks

y ----> the total amount Chem has deposited in a saving account

we know that

The equation of a line in slope intercept form is

$y=mx+b$

where

m is the rate or slope of the linear equation

b is the y-intercept of the linear equation or initial value (value of y when the value of x is equal to zero)

In this problem we have that

The rate or slope is equal to

$m=35\frac{\$}{week}$ -----> amount deposited by Chem each week

The y-intercept or initial value is

$b=\$115$ ----> amount deposited originally in the saving account

substitute the values

$y=35x+115$

Part b) How much has Chem deposited 30 weeks after his initial deposit?

For x=30 weeks

substitute in the equation

$y=35(30)+115$

$y=\$1,165$

Solve for x

vova2212 [387]

$\frac{x-8}{2} =-3$
Common denominator is 2
$\frac{\not2(x-8)}{\not2} =2(-3)$
$x-8=2(-3)$
$x-8=-6$
Add 8
$x=-6+8$
$x=2$
The answer is : D.2
