Answer:
The p value for this case would be given by:
For this case since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly different from 31.3 MPG
Step-by-step explanation:
Information given
represent the sample mean
represent the population standard deviation
sample size
represent the value that we want to test
represent the significance level for the hypothesis test.
z would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true mean is equal to 31.3 MPG, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
Since we know the population deviation, the statistic is given by
(1)
Replacing we got:
The p value for this case would be given by:
For this case since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true mean is not significantly different from 31.3 MPG
Answer: A
Step-by-step explanation:
The answer is A.
y≤-2x+3 .... (1)
y≤x+3 ..........(2)
In the system is inequality above, the f(x) is a negative graph while the g(x) is a positive graph.
The two function have different gradients ( slope) so, the will surely have the intersecting portion or area where f(x) and g(x) have shading in common which is labeled AB.
Answer is C.
3x and 4x² are not like terms, as their exponents do not share the same power (3x has a power of 1, 4x² has a power of 2)
The answer is A.
You can recognize the pattern of an exponential equation to know the answer, but to prove it, the easiest way is to inspect the elements and find exponential.
In this case, y = 2^x power
2^1 = 2
2^3 = 8
2^5 = 32
2&7 = 128
That is the best reason for the answer I can give sadly.
Answer:
121
Step-by-step explanation:
First do the parenthesis. Now your equation is (11)^2 Next do exponents. Your equation now is 121.
Hope this helped and have a great day!
