uppose germination periods, in days, for grass seed are normally distributed and have a known population standard deviation of 2

natka813 [3]

Answer: 0.701

Step-by-step explanation:

Formula : $EBM =z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$ , where $\alpha=$ significance level , $\sigma =$ Population standard deviation, n= sample size.

As per given, n= 22

$\sigma = 2$

Critical z- value for 90% confidence level : $z_{\alpha/2}=1.645$

Then,

$EBM =(1.645)\dfrac{2}{\sqrt{22}}\\\\=(1.645)\dfrac{2}{4.690416}\\\\\approx0.701$

Hence , error bound (EBM) of the confidence interval with a 90% confidence level= ± 0.701

Answer:

$V_{composite\: figure} =678.24\: in^3$

Step-by-step explanation:

For a single cylinder:

radius (r) = 3 in (Given)

height (h) = 8 in (Given)

It is given that: all the three cylinders are identical, means their radii and heights are equal.

Thus, the volume of composite figure will be equal to three times the volume of single cylinder.

$\implies V_{composite\: figure} =3(\pi r^2 h)$

$\implies V_{composite\: figure} =3(3.14\times (3)^2 \times 8)$

$\implies V_{composite\: figure} =3(226.08)$

$\implies V_{composite\: figure} =678.24\: in^3$

Susanna found a roll of fabric she want to use to make a pillow. The role head 3/4 of a yard of fabric left. Suzanne need 1/3 of

balu736 [363]

$\frac{1}{4}$ represents the amount of fabric Susanna needed.

Step-by-step explanation:

Given,

Remaining fabric = $\frac{3}{4}\ of\ yard$

Fabric Susanna needs = $\frac{1}{3}\ of\ remaining\ fabric$

Fabric Susanna needs = $\frac{1}{3}*\frac{3}{4}$

Fabric Susanna needs = $\frac{1}{4}\ of\ a\ yard$

$\frac{1}{4}$ represents the amount of fabric Susanna needed.
