Answer:
Step-by-step explanation:
In the fifth grade class, 
of the girls have brown hair. Again among those of the brown-haired girls, 
of them have long hair.
We are asked to find the fraction of the girls who have long brown hair in the class.
The fraction of the total students which have long brown hair will be (
) = . (Answer)
Step-by-step explanation:
here is the graph step by step to tell you the interval over which f x is increasing
If interest is 5 percent then you add 5 for every 100 so
6x5=30
then you add 30 to 600 so your answer is 630
Using a calculator, the slope of the line of best-fit is of 7.2.
<h3>How to find the equation of linear regression using a calculator?</h3>
To find the equation, we need to insert the points (x,y) in the calculator.
In this problem, the points are given as follows:
(-4,-32), (-2,-8), (0,10), (2,8), (4,32).
Using the calculator, the equation is:
y = 7.2x + 2.
Hence the slope is of 7.2.
