Answer:

32x^3 + 4x^2 + 41x - 35

Step-by-step explanation:

Multiply each of the terms in bracket 1 with those in bracket 2.

4x^2 x 8x = 32x^3

4x^2 x -5 = -20x^2

3x x 8x = 24x^2

3x x -5 = - 15x

7 x 8x = 56x

7 x -5 = -35

Now, put them together and simplify:

32x^3 - 20x^2 + 24x^2 - 15x + 56x - 35

After simplifying:

32x^3 + 4x^2 + 41x - 35

Alja [10]

Answer: 554

Step-by-step explanation:

Formula we use to find the sample size :

$n=(\dfrac{z_{\alpha/2}\cdot\sigma}{E})^2$

Given : Standard deviation : $\sigma=3\ hour$

Margin of error : E=one quarter hour = 0.25 hour

Two-tailed , Critical value use for 0.95 degree of confidence: $z_{\alpha/2}=1.96$

i.e. $n=(\dfrac{(1.96)\cdot(3)}{0.25})^2=553.1904\approx554$

Hence, the required sample size = 554

i.e. 554 executives should be surveyed.

Which of the following is would most likely negatively affect a person’s net worth

coldgirl [10]

Step-by-step explanation:

Net Worth

Your assets are anything of value that you own that can be converted into cash. Examples include investments, bank and brokerage accounts, retirement funds, real estate and personal property (vehicles, jewelry, and collectibles)—and, of course, cash itself. Intangibles such as your personal network are sometimes considered assets as well. Your liabilities, on the other hand, represent your debts, such as loans, mortgages, credit card debt, medical bills, and student loans. The difference between the total value of your assets and liabilities is your net worth.
