The result of dividing $15x^{3}+x^{2}-3x+2$ by $3x+2$ is $5 x^{2} -3x+1$ with no remainder. Please check the step by step procedures in the picture attached.
We can conclude that:
The quotient of the division is $5 x^{2} -3x+1$
The remainder of the division is $0$
The divisor is $3x+2$
The dividend is $15x^{3}+x^{2}-3x+2$

Answer:

Step-by-step explanation:

Using Simple Random Sampling, we can estimate the sample size by the formula

$\bf n=\frac{Z^2S^2}{e^2}$

where

n = sample size

Z = the z-score corresponding to the confidence level 99.5%

S = the assumed standard deviation = 3 seconds

e = margin of error = 2 seconds

It is worth noticing that the higher the confidence level, the larger the sample should be.

The z-score corresponding to a confidence level of 99.5% can be obtained either with a table or the computer and equals

Z = 3.023

Replacing the values in our formula

$\bf n=\frac{(3.023)^23^2}{2^2}=20.5616\approx 21$

So the size of the sample should be at least 21.
