Ede4ka [16]

Answer: (12.007\ , \ 12.033)

Step-by-step explanation:

Given : Sample size : n= 36 , which is a large sample (n>30) so the test applied here is z-test.

Significance level : \alpha: 1-0.95=0.05

Using Standard normal table , Critical value : z_{\alpha/2}=1.96

Sample mean : \overline{x}=12.02

Standard deviation: \sigma= 0.04

The confidence interval for population means is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

i.e.12.02\pm(1.96)\dfrac{0.04}{\sqrt{36}}

\approx12.02\pm0.013=(12.02-0.013,\ 12.02+0.013)\\\\=(12.007\ , \ 12.033)

Hence, the 95 percent confidence interval for the fill rate = (12.007\ , \ 12.033)

Solve the formula A=10+ry. solve for y
noname [10]

The given formula A= 10 + ry

Solve for y means we have to make y alone

A= 10 + ry \\

Add -10 on both sides, we get

A - 10 = 10 -10 + ry \\A - 10 = 0 + ryA - 10 = ry

As there is multiplication sign between r and y so to solve for y, divide both side by r

\frac{A - 10}{r} = y\\\\y = \frac{A - 10}{r}
