Answer:
p=25
Step-by-step explanation:
-5[-9=- -4] Get rid of the fraction by multiplying the whole equation by -5.
45=p+20 Then, subtract 20 from both sides.
25=p
Answer:
The answer is "3".
Step-by-step explanation:
If the compression factor of 3 is modified, the k value is 3 For a function f(x) the horizontal extending or compression is provided by g = f (bx)
Here b is constant. Where b is constant.
If b> 0, the function graph is condensed. The fact that perhaps the function is transformed by an encoding factor of 3 is given in the question.
Answer:
Since we know the population deviation, is better apply a z test to compare the actual mean to the reference value, and the statistic is given by:
(1)
z-test: "Is used to compare group means. Is one of the most common tests and is used to determine if the mean is (higher, less or not equal) to an specified value".
The best answer would be:
A. Z test
Step-by-step explanation:
Data given and notation
represent the mean average
represent the population standard deviation for the sample
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
z would represent the statistic (variable of interest)
represent the p value for the test (variable of interest)
State the null and alternative hypotheses.
We need to conduct a hypothesis in order to check if the mean is equal or not to 37100, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
