Zarrin [17]

Answer:

$Height=10\, inches$

Step-by-step explanation:

Volume of a Rectangular Prism is :

$Length\times Width \times Height$

For,

$Volume=200\,inch^3\\\\Length= 8\,inches\\\\Width=2\dfrac{1}{2}=\dfrac{5}{2}\\\\ Height=?\\$

$200=8\times \dfrac{5}{2}\times Height\\\\ 200=4\times 5\times Height\\\\200=20\times Height\\\\Height=\dfrac{200}{20}\\\\ Height=10\,inches$

The Height of the rectangular prism is: $10\,inches$

Answer:

The confidence interval is -5.3444 to 6.453 .

Step-by-step explanation:

We are given that In a survey of 458 likely voters, 254 said that they would vote "yes" on the referendum.

So, n = 458

x = 254

We will use sample proportion over here

$\widehat{p}=\frac{x}{n}$

$\widehat{p}=\frac{254}{458}$

$\widehat{p}=0.5545$

Confidence level = 95% = 0.95

Level of significance = 1-0.95 = 0.05

z value at 0.05 significance level = 1.96

Formula of confidence interval : $\widehat{p}-x\times \sqrt{\frac{\widehat{p} \times (1-\widehat{p})}{n}$ to $\widehat{p}+x\times \sqrt{\frac{\widehat{p} \times (1-\widehat{p})}{n}$

Confidence interval : $0.5545-254\times \sqrt{\frac{0.5545\times (1-0.5545)}{458}}$ to $0.5545+254\times \sqrt{\frac{0.5545\times (1-0.5545)}{458}}$

Confidence interval : $-5.3444$ to $6.453$

Hence The confidence interval is -5.3444 to 6.453 .
