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:
sorry for the late answer but it's a, b, and d. hope it helps :)
Answer:
So add all the numbers together 0.75 + 0.75 = $1.50
Then $1.50 + $1.09 = $2.59
Next $2.59 + $0.68 = $3.27
Also $3.27 + $0.07 + $0.80 = $4.14
You have $4.14 that you spent. The cashier should give you back $5.86.
So yes, you gave the cashier enough money and you got back money too.
