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

zhenek [66]

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

\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.
