Answer:
A = 120
C = 45
Step-by-step explanation:
(12x + 12) + 15 + (3x + 18) = 180
(12x + 3x) + (12 + 15 + 18) = 180
15x + 45 = 180
15x = 180 - 45
15x = 135
x = 135/15
x = 9
A = 12x + 12 = 12(9) + 12 = 108 + 12 = 120
C = 3x + 18 = 3(9) + 18 = 27 + 18 = 45
Let is the answer for the question
Answer:
The answer is D: The inequality symbol in the alternative hypothesis points away from the critical region.
Step-by-step explanation:
We usually have a one-tailed and two-tailed tests. Examples of a one-tailed test are the left-tailed and the right tailed test. These tests are referred to as one-tailed tests because the critical region or rejection region is located in only one tail. The critical region of a left or right tailed test is that region that correlate with the rejection region and is usually located in extreme left or right tail. Furthermore, tails in a distribution are usually the extreme critical regions also known as the rejection regions which are bound by critical values. However there is nothing that suggests the statement in Option D when talking about tails in a distribution.
Answer:
3
Step-by-step explanation:
Answer:
Step-by-step explanation:
we have
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
Take square root both sides
Adds 5 both sides
