Answer:

-1 23/40

Step-by-step explanation:

Rewriting this by starting with the negative sign results in

-334 ÷ (212) .

Writing that sign, and then evaluating 334/212 on a calculator, we get:

-1.575 (approximately), which can be rewritten as -1 23/40. This last result is a mixed number in simplified form. Note that -1.575 has been rounded off from a version with 9 decimal places.

True or False

Hitman42 [59]

Answer:

True

Step-by-step explanation:

To find the average of anything, you add their values together, and then divide that number by how many of them you added.

Here, you are trying to calculate monthly expenditure, so you add their values together (the sum of monthly expenditures) and then you divide it by how many months you used to add up to the sum (divided by the number of months).

Hope this helped ya! :)

Using the Central Limit Theorem, it is found that the mean of the sampling distribution of sample proportions is 0.37.

The Central Limit Theorem establishes that, for a proportion p in a sample of size n, the sampling distribution of sample proportions has:

Mean $\mu = p$ .

Standard error $s = \sqrt{\frac{p(1 - p)}{n}}$

For this problem, about 37% of high school seniors have vaped in the past year, hence $p = 0.37$ .

Then, the mean of the sampling distribution of sample proportions is 0.37.

The revenue from manufacturing and selling x units of toaster ovens is given by:

nexus9112 [7]

Answer:

$248,000.

Step-by-step explanation:

We have been given that the revenue from manufacturing and selling x units of toaster ovens is given by $R(x)=-0.3x^2+200x-82,000$ .

To find the amount of revenue earned from selling 3,000 toaster, we will substitute $x=3,000$ in the given formula as:

$R(3,000)=-0.03(3,000)^2+200(3,000)-82,000$

$R(3,000)=-0.03*9,000000+600,000-82,000$

$R(3,000)=-270,000+518,000$

$R(3,000)=248,000$

Therefore, the company should expect revenue of $248,000 from selling 3,000 toaster ovens.
