Answer:
The dividend is 51 and the divisor is 13.
Step-by-step explanation:
Since the remainder is 12, so the divisor must be greater than 12.
So, we can choose any number as a divisor which is greater than 12.
Assume the divisor is 13.
So, when we divide the dividend say, x by the divisor 13 then the quotient will be 3 and the remainder will be 12.
Therefore, x = 13 × 3 + 12 = 51
So, the dividend is 51 and the divisor is 13. (Answer)
Answer:
standard error = 1.63
Step-by-step explanation:
To calculate the standard error we need to know the standard deviation (σ) and the sample size (n) (see the attached formula).
To obtain the standard deviation we use the given sample variance of 77.4 years:
σ²= variance
Therefore:
σ = √77.4 = 8.8
Now we can calcuate the estimated standard error:
standard error = σ /√n = 8.8/√29 = 1.63
The standard error gives us an estimation about how far the mean of the sample is from the mean of the entire population, and in this case is 1.63.

The answer is 24/35. i would tell you to simplify but it is already in its simpliest form.
