Answer:
X=60
Step-by-step explanation:
Sum of the Quadrilateral interior angles:360
360-70-130-100=60
Answer:
19
Step-by-step explanation:
If you divide 57 by 3, the answer you will get is 19. Hope this helped!
C : B = D : E
6 : 5 = D : 3
D = 3.6
Using the confidence interval, it is found that the correct conclusion regarding the hypotheses test is given by:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
<h3>What are the hypotheses tested?</h3>
At the null hypotheses, it is tested if the mean is of 150, that is:

At the alternative hypotheses, it is tested if the mean is different of 150, hence:
.
The confidence interval is (158, 167). Since it does not contain 150, we reject the null hypotheses, hence the correct option is:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.

Step-by-step explanation:
(2^2x²/xy²) for x=3 and y=2
we have
2^2(3)²/((3)(2²))
2^2(9)/((3)(4))
2^18/12
