Answer:
owe money 24,000
Step-by-step explanation:
Answer:
A OR C
Step-by-step explanation: I think it is A because in the question it says y=3
then y=ax²+b and on the A) it says a= -2 and b=2 OR the answer might be C) because it says ax² and a=<u>2 </u>
<u></u>
<u>im sorry if both of these are wrong and im sorry if you don't understand what i mean but i hope i helped you . :)</u>
Using the <em>normal distribution and the central limit theorem</em>, it is found that the probability the mean cost of the weddings is more than the mean cost of the showers is of 0.9665.
<h3>Normal Probability Distribution</h3>
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, the sampling distribution of sample means of size n has standard deviation
.
- When two variables are subtracted, the mean is the subtraction of the means, while the standard error is the square root of the sum of the variances.
<h3>What is the mean and the standard error of the distribution of differences?</h3>
For each sample, they are given by:


For the distribution of differences, we have that:


The probability the mean cost of the weddings is more than the mean cost of the showers is P(X > 0), that is, <u>one subtracted by the p-value of Z when X = 0</u>, hence:

By the Central Limit Theorem



has a p-value of 0.0335.
1 - 0.0335 = 0.9665.

Answer:
h = 24 ft
Step-by-step explanation:
A = 936 ft^2, b = 39 ft.
A = bh
Divide both sides by b:
h = A/b = 936 ft / 39 ft = 24 ft
