The square root of 37 is 6.08. that means that no number squared can equal 37
First we know that a dozen is 12
so She makes 12×15 cookoes which is
180 cookies
so lets put it in an equation.
36 cookies = 1 cup butter
180 cookies = X
The criss cross method
36 X = 180 cup of butter (notice here that the cookie cancelled out)
dividing each side by 36 we get
5 cups of butter
Since the problem is quite vague because the number of
choice per question is not written here. I’ll just put for 4 choices and 5
choices each.
To compute for the 5 choices each:
Mean = np = 20 (1/5) = 4
Standard deviation = sqrt(npq) = sqrt (4*(4/5) = 1.79
To compute for the 4 choices each:
Mean = np = 20 (1/4) = 5
Standard deviation = sqrt(npq) = sqrt (5*(4/5) = 2
Answer:
87.5%
Step-by-step explanation:
It decreased by 16 - 2 or 14, and since he wrote 16 tickets last week, the answer is 14/16 in percent form, or 7/8 = 87.5%.
