Answer:
Step-by-step explanation:
From the dot plot of start of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 5
Range of the data set = 10 - 5
= 5 miles
From the dot plot of End of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 6
Range of the data set = 10 - 6
= 4 miles
The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.
It's D, y=0.078x + 29 works with all of the numbers
At a certain time of day, a 5.5 foot tall man has a 6 foot shadow. if a tree is 19.25 feet tall, what is the length of the shadow of the tree(x=shadow of the tree)
the equation for the problem is...
5.5/6=19.25/x
you then multiply the denominators on both sides...
5.5x=19.25*6
you then solve on one side...
5.5x=115.5
and then divide 5.5 on both sides to leave x alone...
x=21
the shadow of the tree is 21
