Circle Phas a circumference of approximately 75 inches.
2 answers:
Answer:
12 inches
First choice
Step-by-step explanation:
Solve using the formula for circumference.
C = 2πr
"C" is the circumference, which we know C = 75 in.
π = 3.14 in this problem.
"r" is the radius, which we are finding.
Substitute the numbers you know for the variables of the formula.
C = 2πr
(75in) = 2(3.14)r
Since we are finding "r", we need to isolate it. If we divide the right side by 2(3.14), it cancels out and "r" will be alone.
Put the variable on the left side for standard formatting.
Now simplify the fraction.
2 times 3.14 is 6.28
Divide the top by the bottom
r = 11.9426752 in Exact decimal answer
r ≈ 12in Rounded answer to nearest inch

Answer: Side of largest square tile will be 105 feet.
Explanation:
Since we have given that
dimensions of the wall is 42 feet by 10 feet
So,
Length of wall = 42 feet
Breadth of wall = 10 feet
First we calculate the H.C.F. of 42 and 10,
which is 2 only.
The largest square tile side would be 2 feet.
Now, we find the number of tiles used,
Number of tiles =
We get integer value of number of tiles.
Therefore, Side of largest square tile will be 2 feet.
Answer:
Option B) Reject null hypothesis
Step-by-step explanation:
We are given the following in the question:
We are given the null hypothesis:
Two tailed z-test
Now,
Since,
The calculated z-statistic does not lie in the acceptance region, we fail to accept and reject the null hypothesis.
Left-tailed z-test
Now,
Since,
We fail to accept and reject the null hypothesis.
Right-tailed z-test
Now,
Since,
We fail to accept and reject the null hypothesis.
