less means "subtract", than means "reverse the order", triple means "times 3"
width: 3m - 5
Answer: 3m - 5
Answer:
y = 2(31x + 336)
Step-by-step explanation:
The surface area of an open rectangular box of sides, l, w and h is
A = 2lh + 2wh + lw where l = length = x, w = width = 14 in and h = height = 24 in.
Since A = y, we have
y = 2lh + 2wh + lw
y = 2x(24) + 2(24)(14) + x(14)
y = 48x + 672 + 14x
y = 62x + 672
y = 2(31x + 336)
Answer:
Needed point estimate is $372
Step-by-step explanation:
Given:
Number of houses in resident area = 121
Monthly mean car payment = $372
Find:
Best point estimate for the mean monthly car payment
Explanation:
The "best point estimate" for such average monthly automobile payment for all inhabitants of the nearby apartment complex is used as the "sample mean." In this example, a $372 sample was obtained on 121 residents.
As a result, the needed point estimate is $372.
