Answer:
2x + 3 (x=mary)
Step-by-step explanation:
3 more that twice (times 2) as many as mary.
3 + 2x
2x + 3
Answer:
W = 6
Step-by-step explanation:
L x W x H = V
L = 4W
H = W + 4
V = 1440
Plug in and solve for W.
4W x W x (W+4) = 1440
4W^2 x (W+4) = 1440
W^2 (W+4) = 360
A combo that came quickly to mind was 36 and 10 to make 360.
6^2 = 36
6 + 4 = 10
36 x 10 = 360
Therefore, W = 6.

Answer:
0.6
Step-by-step explanation:
Given the regression equation :
y = 0.2x + 3,
The actual value of y when x = 5 is 4.6
The predicted of y using the model when x = 5 is :
Put x = 5 in the equation :
y = 0.2(5) + 3
y = 1 + 3
y = 4
The error in the value of y predicted is :
Error = Actual value - Predicted value
Error = 4.6 - 4
Error = 0.6
