Answer:
okay it simple the answer is D
Step-by-step explanation:
im just smart I guess
The answer is B because in g(x)=x+3 x=2 so it would be g(2)=2+3 so g(2)=5. So you plug in five and do f(5)=5*3+4 and 5 to the power of 3 is 125 and you add 4 so you get 129

Answer:
Step-by-step explanation:
The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. This is the null hypothesis. It is written as
H0 : µ ≤ 34
The alternative hypothesis would be
Ha : µ > 34
This is a right tailed test because of the greater then symbol in the alternative hypothesis. Since the p value for the test was found to be 0.0281281, if we use a significant level of 0.05, then the conclusion would be
Reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average time spent on the deliveries does exceed 34 minutes.
Answer:
P98 = 16.154in
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score 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 p-value, we get the probability that the value of the measure is greater than X.
Men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 1.0 in.
This means that
Find P98
This is the 98th percentile, that is, X when Z has a pvalue of 0.98, so X when Z = 2.054.
So
P98 = 16.154in
