C because if you divide 3/12 you get .25 but 4/18 is .22, which is the better deal
Answer:
Option C: 15.87 is the correct answer
Step-by-step explanation:
Given
Mean = $47500
SD = $12500
We have to find the probability of having $60000 or more
So,
x = $60000
The z-score will be:

Looking in the z-score table, we get
P(Z<60000) = 0.8413
In order to find the probability P(Z>60000) => 1-P(Z<60000)
= 1-0.8413
=0.1587
Converting into percentage: 0.1587*100 = 15.87%
Hence,
Option C: 15.87 is the correct answer
Answer:
The 6x6 cube is 1/4 the area of the 12x12 cube.
100%=$1,636,364 (Rounded to the dollar)
Step-by-step explanation:
6x6=36
12x12=144
36/144=1/4
_____________________
20%=?
25%=?
Remainder (55%=$900,000) so:
100%=$900,000/.55
100%=$1,636,364
By the formula for the area of an equilateral triangle (s^2sqrt(3)/4), the area is sqrt(3)/4.
