Answer:
t= 1/2
Step-by-step explanation:
hope this help
The answer is D because if you add 4 7/10 which is 4.7 and add 5 4/5 which is 5.8 it is 4.7 plus 5.8. That equals 10.5 which is equal to the answer of 10 1/2. If this is right could I possibly get brainliest?
Answer:
We need a sample size of at least 657.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is given by:

45 percent of its claims have errors.
So 
99% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
What sample size is needed if they wish to be within 5 percent of the actual
This is a sample size of at least n, in which n is found when M = 0.05.







We need a sample size of at least 657.
Answer:
We have the equation:
(14 N/mm)*X = Y N/cm
So we want to transform 1/mm to 1/cm.
We know that:
10mm = 1cm
1 = 10mm/1cm (we want to have mm on the numerator, so it cancelates with the mm in the denominator)
then the conversion is from 1/mm to 1/cm is:
X = 10mm/cm
then we have:
(14N/mm)*(10mm/cm) = 140 N/cm
