Answer:
14.81% probability an individual large-cap domestic stock fund had a three-year return of at least 19%
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation , the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the probability an individual large-cap domestic stock fund had a three-year return of at least 19%
This is 1 subtracted by the pvalue of Z when X = 0.19. So
has a pvalue of 0.8519
1 - 0.8519 = 0.1481
14.81% probability an individual large-cap domestic stock fund had a three-year return of at least 19%

Answer:
x=6
Step-by-step explanation:
2 (x-4) +3 =7
Subtract 3 from each side
2 (x-4) +3-3 =7-3
2(x-4) =4
Divide each side by 2
2(x-4)/2 = 4/2
x-4 = 2
Add 4 to each side
x-4+4 =2+4
x=6
