Answer:
63
Step-by-step explanation:
When a quadrilateral is in the circle, the opposite angels are supplementary, meaning they equal 180. So you do 180-117 and get 63
Answer:
no
Step-by-step explanation:
false
irrational numbers cannot be rational
Answer:
E(m) = 12m
Step-by-step explanation:
Your earnings will be the amount of times you mow the lawn * $12 per job
so if m is the amount of times and 12 is the amount your Earnings(E) = 12m
Using the <u>normal distribution and the central limit theorem</u>, it is found that there is a 0.1635 = 16.35% probability of a sample result with 68% or fewer returns prior to the third day.
In a normal distribution with mean
and standard deviation
, the z-score of a measure X is given by:

- It 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, which is the percentile of X.
- By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportions has mean
and standard error 
In this problem:
- Sample of 500 customers, hence
.
- Amazon believes that the proportion is of 70%, hence

The <u>mean and the standard error</u> are given by:


The probability is the <u>p-value of Z when X = 0.68</u>, hence:

By the Central Limit Theorem



has a p-value of 0.1635.
0.1635 = 16.35% probability of a sample result with 68% or fewer returns prior to the third day.
