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
Answer:
5 11/12 cups of melon
Step-by-step explanation:
The cups of melon he puts in the fruit salad is:
Number of cups of orange melon + Number of cups of green melon
= 3 1/4 cups + 2 2/3 cups
3 + 2 + (1/4 + 2/3)
The Least common denominator is 12
5 + (3 × 1 +4 × 2/12)
5 + (3 +8/12)
5 11/12 cups
Therefore, Jason put in 5 11/12 cups of melon in the fruit salad.
Your answer is n=2. thank me if this helped you. :)
Answer:
X-intercept: (1.5,0)
y-intercept: (0,-2)
the 1.5 can also be written as 3 over 2 in fraction form.
Hope this helps! :)
