Answer:
c. 4.27
Step-by-step explanation:
We have been given the regression equation of for predicting number of speeding tickets (Y) from information about driver age (X) as 
.
To find the predicted number of tickets for a twenty-year-old, we will substitute 
in our given equation.
Therefore, the predicted number of tickets for a twenty-year-old would be 4.27 tickets.
Area of a triangle= bh/2b=4in h=8in8x4/2=16in
there are 4 triangles
4x16=64
area of a rectangle=bh
4x4=16
64+16=80in^2
Answer:
The perpendicular bisector meets any line at an angle which is not 90°
Step-by-step explanation:
Answer: P = 2x + 2y + 10
Step-by-step explanation: The perimeter (P) of a rectangle is given as
P = 2L + 2W
By factorizing the right hand side of the equation we now have
P = 2(L + W)
However, the length of the rectangle is given as x + 6 and the width is given as y - 1
If P = 2(L + W), then
P = 2(x + 6 + {y - 1} )
P = 2(x + 6 + y -1)
P = 2(x + y + 5)
After expanding the bracket, we now have
P = 2x + 2y + 10
Answer:
$70
Step-by-step explanation:
break it down, 100% of 40 is 40, and 75% of 40 is 30, so add 40 and 30 to get 70
