The scatter plot below shows the total time (/), in minutes, 13 students spent working on their research papers based on the number of books (x) they used as resources
Time Spent on
Research Papers

Based on the scatter plot, which equation represents the line of best fit for the time the students spent working on research
papers?
A. y = 70.28x + 285.21
B. y = 87.5x
C. y = 87.5x + 700
D. y = 70.28x

a precentage of 6th graders. the population is all 6th graders. let me know if i'm wrong, i hope this ! : )

step-by-step explanation:

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
