What is 35% of 35? please included how you got it!!

ruslelena [56]

$\huge\boxed{12.25}$

First, convert the percentage to a decimal. You can do this by moving the decimal place two places to the left.

$35\%\longrightarrow0.35$

Now, simply multiply that decimal by $35$ using a calculator.

$0.35*35=\boxed{12.25}$

A piece of cloth is required to completely cover a solid object. The solid object is composed of a hemisphere and a cone surmoun

Otrada [13]

Answer:

▶(B) 463.39 m²

<h3>Step-by-step explanation:</h3>

$\space$

Surface area of hemisphere = 2πr²

=> 2×22/7× (7)² = 308 m²

☯<u>For calculating the surface area of a cone we need to calculate its slant height,</u>

$\sf{ \leadsto \: 1 = \sqrt{49 + 1} = \sqrt{50 \: } m}$

$\space$

$\sf{ \leadsto \: \pi \ r1 = \frac{22}{7} \times 7 \times \sqrt{50} = 463.39 \: {m}^{2} }$

$\: \:$

Hope it helps!

Have a great day! :)

Consider estimating a population proportion p. What is the most conservative sample size (erring on the large size) required in

just olya [345]

Answer:

The most conservative sample size is 2401.

Step-by-step explanation:

We are given the following in the question:

We are not given any approximation of s]ample proportion, thus,

$\hat{p} = 0.5$

We have to construct a 95% confidence interval.

Margin of error = 2% = 0.02

Formula for margin of error =

$z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$0.02 = 1.96\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}\\\\0.02 = 1.96\times \sqrt{\dfrac{0.5(1-0.5)}{n}}\\\\\sqrt{n} = 1.96\times \dfrac{\sqrt{0.5(1-0.5)}}{0.02}\\\\\sqrt{n}=49\\n = 2401$

Thus, the most conservative sample size is 2401.
