The following data gives the number of hours 7 students spent studying and their corresponding grades on their midterm exams. Hours Spent Studying 0 0.5 1.5 2.5 4 4.5 5.5 Midterm Grades 60 63 72 78 81 93 96 Step 2 of 3 : Determine if r is statistically significant at the 0.01 level.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.

step-by-step explanation:

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

this is a good question! i'll do some research and come back when i have the answer!
