Answer:
A
Step-by-step explanation:
Because the angle with measure 124 degrees and angle y are a linear pair, their values must add up to 180 degrees. Therefore, y=180-124=56 degrees. Since all of the angles in a quadrilateral add up to 360 degrees, x must be 360-56-65-125=114 degrees. This means that the correct answer is choice a. Hope this helps!
urrrrrrrrrrr....... bro why you bully
Answer:
51.36 = 2 x 25.68 & 77.04 = 3 x 25.68

All you need to do is times 2 & 3 with 25.68 & you'll get your answer.
Answer:
If you meant to simplify the expression,
-8b+4ab
if factor: 4b(a-2)
Step-by-step explanation:
To simplify an expression, combine the like terms.
8b+4ab-16b, 8b and -16b are like terms.
-8b+4ab, notice 4ab has an extra a before the b, so it is not a like term of -8b
To factor it out:
The expression -8b+4ab both includes b in it.
Thus,
b(-8+4a) -8 and 4 can be has GCF of 4
=4b(a-2).
Answer:
(iii) The conclusion of a right tail hypothesis test (test of significance) for a population mean at the significance level should always match the conclusion of a two-sided confidence interval for estimating the same population mean at the confidence level 1- (iv) Keeping all other quantities fixed, increasing the significance level will increase the power of the test.
Explanation:
Improving your process decreases the standard deviation and, thus, increases power. Use a higher significance level (also called alpha or α). Using a higher significance level increases the probability that you reject the null hypothesis. ... (Rejecting a null hypothesis that is true is called type I error.)
Increase the power of a hypothesis test
1. Use a larger sample. ...
2. Improve your process. ...
3. Use a higher significance level (also called alpha or α). ...
4. Choose a larger value for Differences. ...
5. Use a directional hypothesis (also cathe called a one-tailed hypothesis).
