To be a right triangle, the hypotenuse^2 must equal side1^2 + side2^2
Only set 2 meets these conditions
8, sq root (29), sq root (35) then squaring these:
64, 29, 35
64 = 29 + 35
Answer: it is a right tailed probability
Step-by-step explanation:
Population proportion = 26.9/100 = 0.269
We are dealing with the fact that the probability that the mean bond percent for the sample will be at least 28. This means that the sample proportion is 0.28 or above. This means that it is greater than the population proportion of 0.269
The hypothesis would be
For null hypothesis
p = 0.269
For alternative hypothesis,
p > 0.269
The inequality sign means that it is right tailed.
Answer:
I believe it is A
Step-by-step explanation:
Answer:
π
The desired formula is y = 3cos(----- t) + 5
5
Step-by-step explanation:
From maximum point to minimum point, the change in x is 5 and the change in y (min to mx) is (8 - 2), or 6. The graph repeats itself beginning at x = 6 and thus has period 10 (e. g., from first max to next max).
2π
Period and frequency are related through period = ------
b
and so if the period is 10 (as it is here),
2π 2π π
period = 10 = ------------ Therefore, b = ------- = -------
b 10 5
π
The desired formula is y = 3cos(----- t) + 5
5
3 is the amplitude and 5 is the vertical offset from y = 0.
