Hello!

Answer:

$\boxed{x=4}$

The answer should have a positive sign.

Step-by-step explanation:

First, you do is expand.

5(x-10)=5x-50

5x-50=30-15x

Then add by 50 both sides of an equation.

5x-50+50=30-15x+50

Simplify.

5x=-15x+80

Next add 15x both sides of an equation.

5x+15=-15x+80+15x

Simplify.

20x=80

Divide by 20 both sides of an equation.

20x/20=80/20

Simplify and solve.

80/20=4

$\boxed{x=4}$ , which is our final answer.

Hope this helps you!

Have a nice day! :)

Thanks!

Answer:

x = 4

Step-by-step explanation:

This equation has 3 terms. Divide all of them by 5 to simplify the equation.

We get:

x - 10 = 6 - 3x

Combining the x terms, we get 4x - 10 = 6, or 4x = 16, or x = 4.

A particular security's default risk premium is 2 percent. for all securities, the inflation risk premium is 1.75 percent and th

larisa [96]

To solve this problem and calculate the security's equilibrium rate of return, you should sum the security's default risk premium (2.00%), the inflation risk premium (1.75%), the real risk-free rate (3.50%), the security's liquidity risk premium (0.25%) and the maturity risk premium (0.85%). So, you have:

ij*=2.00%+1.75%+3.50%+0.25%+0.85%
 ij*=8.35%

A researcher wishes to estimate the proportion of adults who have high-speed Internet access. What size sample should be obtain

slega [8]

Answer: 8359

Step-by-step explanation:

The formula for sample size needed for interval estimate of population proportion :-

$n=p(1-p)(\frac{z_{\alpha/2}}{E})^2$

Given : The significance level : $\alpha=1-0.95=0.05$

Critical value : $z_{\alpha/2}}=z_{0.025}=\pm1.96$

Previous estimate of proportion : $p=0.32$

Margin of error : $E=0.01$

Now, the required sample size will be :-

$n=0.32(1-0.32)(\frac{1.96}{0.01})^2=8359.3216\approx8359$

Hence, the required sample size = 8359
