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.

a senator wishes to estimate the proportion of united states voters who favor new road construction. what size sample should be

Nitella [24]

The size of the sample should be obtained at 2401 in order to be 95% confident

Given that:

Margi of error, $ME=0.02$

Population proportion, $p=0.50$

To Find: The size of the sample that should be obtained in order to be 95% confident

Let the size of the sample be n

Using formula,

$n=(p*(1-p))*(z(0.05/2)/ME)^{2} \\n=(0.5*(1-0.5))*(1.96/0.02)^{2} \\n=0.25*9604\\n=2401$

Therefore, the size of the sample should be obtained at 2401 in order to be 95% confident

Help! with explanations if possible

k0ka [10]

Answer:

5

Step-by-step explanation:

1. according to the condition

$\frac{price \ radio1}{price \ radio2} =\frac{x}{y}$

2. when the both prices are increased the ratio is

$\frac{x+20}{y+20}=\frac{5}{2}$

3. when the both prices are reduced the ratio is

$\frac{x-25}{y-25} =\frac{5}{1}$

4. using the equations written in steps 2&3 it is possible to make up the system of the two equations:

$\left \{ {{\frac{x+20}{y+20}=\frac{5}{2} } \atop {\frac{x-25}{y-25}= \frac{5}{1} }} \right.$

where x=160; y=52.

5. ration x:y=5.
