What is the value of x? 3x−8=8x+4/2 Enter your answer in the box
krek1111 [17]

For this case we must find the value of "x" of the following expression:

3x-8 = \frac {8x + 4} {2}

Multiplying by 2 on both sides of the equation:

2 (3x-8) = 8x + 4\\6x-16 = 8x + 4

Subtracting 8x from both sides of the equation:

6x-8x-16 = 4\\-2x-16 = 4

Adding 16 to both sides:

-2x = 4 + 16\\-2x = 20

Dividing between -2 on both sides:

x = \frac {20} {- 2}\\x = -10

Answer:

x = -10

A laboratory tested 85 chicken eggs and found that the mean amount of cholesterol was 190 milligrams. Assume that the sample sta
Serjik [45]

Answer:   (182.356,\ 197.644)

Step-by-step explanation:

Given : Significance level : \alpha:1-0.95=0.05

Sample size : n=85

Critical value : z_{\alpha/2}=1.96

Sample mean : \overline{x}=190

Standard deviation : \sigma=11.7

The confidence interval for population mean is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}\\\\=190\pm(1.96)\dfrac{11.7}{\sqrt{9}}\\\\=190\pm7.644\\\\=(190-7.644,\ 190+7.644)=(182.356,\ 197.644)

Thus, the 95% confidence interval for the true mean cholesterol content, μ, of all such eggs = (182.356,\ 197.644)

Hence, we conclude that the true population mean of amount of cholesterol lies between 182.356 and 197.644.
