In matching an equation with a graph, there are many ways, one of them i using the Slope Intercept Form of the graph, convert the graph and then compare the slope of the two. I hope you are satisfied with my answer and feel free to ask for ore if you have question and further clarification.
Answer:
120°
I just used a protractor tool lol. I looked it up afterwards as well and 120° is correct.
You just multiply the numbers to get 6.14448
Answer:
The degrees of freedom are given by:
And the p value would be given by:
Step-by-step explanation:
Information given
represent the sample mean
represent the sample standard deviation
sample size
represent the value to verify
t would represent the statistic
represent the p value
Hypothesis to test
We want to test if the true mean is higher than 24.5, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
The degrees of freedom are given by:
And the p value would be given by:
F(x) = - sqrt(x) has the same domain as does + sqrt(x). However, because of that - sign, all of the outputs of f(x) will be negative, whereas all of the outputs of + sqrt(x) will be 0 or positive.
