Answer:
x = 82
Step-by-step explanation:
The bottom angle is the same as the angle next to x + 6
A straight angle is 180 degrees.
You add the given angles: (x + 6) + (x + 10) = 2x + 16
180 = 2x + 16
- 16 -16
164 = 2x
x = 82
Answer:
Step-by-step explanation:
perp. -5
y + 7 = -5(x - 4)
y + 7 = -5x + 20
y = -5x + 13
I'll tell you the answer but should I graph it, solve for x, solve for y, or what should I solve for?
Answer: One tail test.
Step-by-step explanation:
Given : A sample of 36 observations is selected from a normal population. The sample mean is 12, and the population standard deviation is 3.
Also, The set of hypothesis to conduct a test :-

The kind of test need to perform is dependent upon the alternative hypothesis.
Since, the alternative hypothesis is one tailed (right-tailed), so the test is one tail test.
