B = 2h
Area = 121
1/2 × b × h = 121
1/2 × 2h × h = 121
h × h = 121
h^2 = 121
h = square root of 121
h = 11
The height is 11 kilometers

Step-by-step explanation:
Answer:
angle l = 115
angle k = 115
angle j = 114
angle i = 66
Step-by-step explanation:
angle l = it is opposite to 115 so its the same
angle k = opposite opposing angles with angle l
angle j = 180-66=114 (between 2 parallel lines the sum of 2 angles is 180)
andle i = 180-114=66 (straight line = 180 degrees so subtract angle j to get i)

Answer:
c) t-test of population mean
Explanation:
The t-test statistic is used in hypothesis testing. Here we would use a one sample t test to test our hypothesis. The one sample t test measures the statistical difference between the hypothesized mean and the sample mean. In a one sample t test or single sample t test, a test variable is measured against a test value.
Example we compare our test variable to the hypothesized mean value $75 above.
The t test is used instead of z score when standard deviation is unknown.
Using the t test, we either accept or reject the null hypothesis given alternative hypothesis.
