X=43 ANS. FOR THE FIRST NUMBER.
43+1=44 ANS. FOR THE SECOND NUMBER.
43+2=45 ANS. FOR THE LARGEST NUMBER.
PROOF:
43+44+45=132
132=132
Answer:
True
Step-by-step explanation:
The formula for the area of a circle is πr² where r is the radius. So if 3 is the radius, plug it into the formula:
π(3²)
Simplify it:
π(9)
This can be rewritten as:
9π

Answer:
C. He should run a T-test, and approximating it with a normal distribution would be inappropriate.
Step-by-step explanation:
We are told that the standard deviation is unknown.
Now in statistics, when we know the standard deviation, then we use a Z-test but when we don't know the standard deviation, then we will use a t-test.
Now, the t-test assumes a normal distribution for difference in mean of samples but it doesn't assume so for population.
Thus, we will run a t-test and doesn't need to approximate with a normal distribution.
