Answer:
Hi there!
The correct answer is:
a. 27831.05
Step-by-step explanation:
Since they gave you the equation for the line of best fit: y = 1.9x + 21
a. solve for x: 52900= 1.9x + 21
minus 21 on both sides to get 1.9x = 52879
then divide 1.9 on both sides to get x= 27831.05
It is just asking to find the sum of interior angles
So follow this rule 180(n-2)
180(5-2)
180(3)= 540
So in another words: a+b+c+d+e=540
B) 12.75
Just add them all together
10+15+14+8+18+11+12+12+10+10+17+16=153
The devide the anser by the ammount of numbers you added together
153÷12=12.75
