The expression is
50h+25
50 times the number of hours, "h"
25 representing the one time service fee
Find the slope of the line using the equation (y1-y2)/(x1-x2), which is change in rise over change in run. use any two points, for example (2,-2) and (3,-1). using the formula, (-2-(-1))/(2-3) is the rate of change, giving you -1/-1 as the slope, which is -1. the rate of change is -1.
<span>$7.80/h = 780 cents / 60 minutes = 13 cents per minute</span>
It should be 16, but because there is only 2 examples, I'm not totally sure. But, I hope this helps you! :)
Answer:
D. 47%
Step-by-step explanation:
To find the probability that a student in the survey is a sophomore, we need to find what percentage of the total population are sophomores.
180 sophomores
387 people
180/387 = 0.465
0.465 ⇒ 46.5%
Round to the nearest percent.
46.5% ⇒ 47%
D. 47%
Hope this helps!
