A decrease means it is going into the negative direction on the number line.
This is represented by the integer -11.
Answer:
x = 7
Step-by-step explanation:
The 2 marked angles are Alternate exterior angles ( they are outside the parallel lines ) and are congruent, that is
10x = 9x + 7 ( subtract 9x from both sides )
x = 7
Answer:
Step-by-step explanation:
Corresponding scores before and after taking the course form matched pairs.
The data for the test are the differences between the scores before and after taking the course.
μd = scores before taking the course minus scores before taking the course.
a) For the null hypothesis
H0: μd ≥ 0
For the alternative hypothesis
H1: μd < 0
b) We would assume a significance level of 0.05. The P-value from the test is 0.65. The p value is high. It increases the possibility of accepting the null hypothesis.
Since alpha, 0.05 < than the p value, 0.65, then we would fail to reject the null hypothesis. Therefore, it does not provide enough evidence that scores after the course are greater than the scores before the course.
c) The mean difference for the sample scores is greater than or equal to zero
I think that inches would be most common for height but centimeters and feet could also be used.
