Answer:
C) 63
Step-by-step explanation:
3 cakes translates to 30 minutes each, so 1.5 hours. If he worked 12 hours total and 1.5 were used to make cakes then the rest were used for cupcakes. This means 12-1.5 = 10.5 hours were spent on cupcakes.
Each cupcake takes 10 minutes, which means in 10.5 hours, or 630 minutes, 63 cupcakes can be made. So C
I think when you divide decimals the numbers get bigger but when you divide by a whole number, they get smaller.
First let us calculate for the z score using the formula:
z = (x – u) / s
where x = 8, u is the mean = 12.7 years, s is the
standard deviation
z = (8 – 12.7) / 2.5
z = -1.88
From the standard probability tables, the p value at z =
-1.88 is:
P = 0.0301 = 3.01%
Answer:
B. Yes, because 0.004<0.010.004<0.010, point, 004, is less than, 0, point, 01.
