Find the circumference in terms of pic if the diameter is 2.5

Answer

Step-by-step explanation:

Radius is always half of the diameter so, is equal to .

The Formula for Circumference is

Since we found out the radius, we need to basically substitute (or insert) it into the radius spot so the next step will be:

Then we multiply (2)(1.25) to get an answer of 2.5 (which we already know)

So our answer is going to be

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
