P=2(L+W)
if given one side and the perimiter
(P/2)-L=W
(P/2)-W=L
Answer:
63
Step-by-step explanation:
The formula to when given the number of standard deviations below the mean x =μ - nσ
Where:
x = raw score
μ is the population mean = 75
σ is the population standard deviation = 8.
n = number of standard deviations below the mean
Hence
x = 75 - 1.5 × 8
x = 75 - 12
x = 63
Therefore, Andrey's exam score is 63
Answer:
I'm gonna go with the first choice because it's rational.
Step-by-step explanation:
The regular price is 3.18.
50% off half the price, so you can either divide the regular price by 2 or multiply it by 0.50
3.18 / 2 = 1.59 ( 3.18 *0.50 = 1.59)
so the sale price is 1.59
now subtract the sale price from $5 to find the amount of change they got back:
5.00 - 1.59 = $3.14 change back
