\bf (x-7)(x^2+3x-3)~\hfill \begin{array}{cll} x^2+3x-3\\ \times x\\ \cline{1-1} x^3+3x^2-3x \end{array}~~+~~ \begin{array}{cll} x^2+3x-3\\ \times -7\\ \cline{1-1} -7x^2-21x+21 \end{array}~\hfill \\\\[-0.35em] ~\dotfill\\\\ (x^3+3x^2-3x) +(-7x^2-21x+21)\implies x^3-4x^2-24x+21

notice that all you do is simply multiply the terms of either one by the terms of the other sequentially, then add like-terms.

Nicole deposited $2,000 at 6% simple interest. How long will it be before she has $2,600 in her account?
Mashcka [7]
5 years, you have to make 6% a decimal so it would be 0.06. You would then multiply 2000 and 0.06 and get 120. You keep adding 120 to 2,000 until you reach 2,600. Hope this helped!

The polynomial y = x2 - 5x + 4 has a repeated factor. (It may help to graph the equation.)
joja [24]
SOLUTION:

y = x^2 - 5x + 4

y = x^2 - 4x - x + 4

y = x ( x - 4 ) - ( x - 4 )

y = ( x - 4 ) ( x - 1 )

ANSWER:

Therefore, the answer is:

A. True.

Hope this helps! :)

Which confidence level will yield the interval that we are most confident in containing the actual value of the population param
Sav [38]

Answer:

The confidence level that will yield the interval that we are most confident in containing the actual value of the population parameter is (d) 99.9%

Step-by-step explanation:

the confidence level can be explained simply as a range of values that are well defined and  that  they contain a specified probability that the value of a parameter lies within the confidence level.

for example when we compare a 99.2% confidence level and 99.9% confidence level, when we have a narrow confidence interval 99.2 (say) this implies that there is a smaller chance of obtaining an observation within that interval, so therefore, our accuracy is higher. Also a 99.2% confidence interval is narrower than a 99.9% confidence interval which is wider. The 99.9% confidence interval is more accurate than the 99.2%.

so that is why we concluded that the most confidence level is 99.9%.
