Answer:
On average, the number of breakdowns per day varies from the mean by about 0.28.
Step-by-step explanation:
Answer:
q = 8
Step-by-step explanation:
Given the 2 equations
p + q = 36 → (1)
p - q = 20 → (2)
Add the 2 equations term by term
2p = 56 ( divide both sides by 2 )
p = 28
Substitute p = 28 into (1)
28 + q = 36 ( subtract 28 from both sides )
q = 8

The length of a rectangle is seven less than twice the length of its width.
L = 2W - 7
A = W * L
A = 15
15 = W * L
Substitute the L in terms of W
15 = W * (2W - 7)
15 = 2W^2 - 7W
2W^2 - 7W - 15 = 0
Factorise:
(2W + 3) (W - 5) = 0
Solve for W:
2W + 3 = 0
2W = 0 - 3
2W = 3
W = 3/2
W = 1.5
W - 5 = 0
W = 0 + 5
W = 5
Use the original equation to find L:
L = 2W - 7
L = 2(5) - 7
L = 10 - 7
L = 3
L * W = 15
3 * 5 = 15
