Answer:
40 chocolates
Step-by-step explanation:
30% *C=12
0.3*C=12
C=40
First, you would have to combine 3 1/2 and 4 3/4 pounds. That would be 8 and 1/4 lbs. If she used all but 1 3/8 lbs, you would have to do 8 1/4 minus 1 3/8. That means she used 7 1/8 lbs of fruit.
The equation would be 3/ 12 + 4 3/4 = 8 1/4 - 1/38 = 7 1/8.
According to the empirical rule, the percent of the data points that are below 100 is; 95.44%
<h3>How to use Empirical Rule in Statistics?</h3>
We are given;
Mean; μ = 88
Standard deviation; σ = 6
Sample mean; x' = 100
Formula for z-score is;
z = (x' - μ)/σ
z = (100 - 88)/6
z = 2
Now, from the empirical rule of normal distribution graph attached, we see that at z = 2, the percentage is 95.44%. However, we want to find the percentage that lie below 100. Thus, this is 95.44%
