Answer:
Choice D. a - b = 12 and a = 3b + 5
Step-by-step explanation:
so |a - b| = 12
a = 3b + 5
3b + 5 - b = 12
2b + 5 = 12
b = 7/2
what if b - a = 12
b - 3b - 5 = 12
-2b = 17
b < 0 no.
choice A. works so does choice D.)
Answer:
B) Reject the null hypothesis because the p-value is less than the level of significance
Step-by-step explanation:
Given that in a one-tail hypothesis test where you reject Upper H0 only in the lower tail, it was found that the p-value is 0.0256 if ZSTAT = -1.95.
So p value = 0.0256
But alpha here is 0.10
Since p <0.10
Whenever p is less than alpha, we reject null hypothesis
Hence correct answer is
B) Reject the null hypothesis because the p-value is less than the level of significance
Answer:
Adition property of equality and subtraction [reperty of equality.
Step-by-step explanation:
We can get the circumference of any circle in terms of the radius with this formula. C = 2
r.
Where r is the radius of the circle.
And we will use 3.14 for
.
Plug in all the values.
C = 2 * 3.14 * 2
C = 12.56
So, the circumference of the circle is 12.6 inches when rounded to the nearest tenth.
