Answer:
103
Step-by-step explanation:
Find the area of the rectangle on the top
A = 7*13 = 91
Now find the area of the rectangle on the bottom
13 - (5+5) = 3
11-7 = 4
The dimensions of the bottom rectangle are 3 by 4
A = 3*4 = 12
The total area is 91+12 = 103

Answer:
99.7%
Step-by-step explanation:
we start by getting the z-scores for the values given
We can get the z-scores using the formula below;
z-scores = (x-mean)/SD
for 338.5;
z = (338.5-598.4)/86.7 = -2.99 approximately-3
for 858.5;
z = (858.5-598.4)/86.7 = 3
so we want to get the percentages that lie within 3 standard deviations from the mean
According to the empirical rule, the percentages within 3 SD of the mean is;
100-0.15-0.15 = 99.7%
