Answer:
21.77% probability that the proportion who are satisfied with the way that things are going in their life exceeds 0.85
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.
For proportions p in a sample of size n, we have that 
In this problem:

In a sample of 100 Americans, what is the probability that the proportion who are satisfied with the way that things are going in their life exceeds 0.85
This is 1 subtracted by the pvalue of Z when X = 0.85. So



has a pvalue of 0.7823
1 - 0.7823 = 0.2177
21.77% probability that the proportion who are satisfied with the way that things are going in their life exceeds 0.85
The first one: -7(x) + 4(y) = 24
The second one: 4(x) - 4(y) = 0
4y - 7x = 24 which is reduced to a negative
(-4y + 4x = 0 )
4(x) = 4(y)
-7(y ) + 4(y) = 24
- 3(y) = 24
3(y) = - 24
y-intercept: - 8
x-intercept: -8
The X & Y intercept is: -8, -8

I would say there are 7 oranges out of ten, ummm and
7/10 divided by 9/11
=77/90
