If you're finding diameter or radius based on circumference, use the formula C = πd. You would divide the circumference by pi to get the diameter, then divide the diameter by 2 to get the radius.
If you're finding diameter or radius based on area, use the formula A = πr^2. You would divide the area by pi, then find the square root of that value which is the radius. Just multiply the radius by 2 to find diameter.
Answer:
(a) H0:μ1=μ2; Ha:μ1≠μ2, which is a two-tailed test.
Step-by-step explanation:
We formulate the
H0: μ1=μ2; null hypothesis that the two means are equal and alternate hypothesis that the two mean are not equal.
Ha:μ1≠μ2 Two tailed test
Test statistic used is
t= x1`-x2` / s√n as the variances are equal and sample size is same
T value for 9 degrees of freedom for two tailed test at α = 0.05 is 2.26
P- value for t test for 9 degrees of freedom is 0.125 from the table.
Hence only a is correct .
A product is the result of multiplication.
A quotient is the result of division.
So you're trying to find the quotient of a number (x) and 5 that equals 8.
Try plugging in the answers.
x/5=8
A. x=4
4/5=8 (Incorrect, 4 divided by 5 is 0.8)
B. x=8
8/5=8 (Incorrect, 8 divided by 5 is 1.6)
C. x=40
40/5=8 (Correct, 40 divided by 5 is 8)
D. x=80
80/5=8 (Incorrect, 80 divided by 5 is 16)
So your answer is C. 40
The quotient of 40 and 5 is 8.
The answer for t is 4 and the proportional relationship is 9
