Answer:

$V=90$

Step-by-step explanation:

Step 1: Find the volume of the cone

$V = \frac{\pi *r^{2}*h}{3}$

Plug in the values

$V = \frac{\pi *3^{2}*10}{3}$

Simplify and Solve

$V = \frac{\pi *9*10}{3}$

$V = \frac{90\pi }{3}$

$V = \frac{90*3 }{3}$

$V=90$

Answer: $V=90$

In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport. in the same district, 19 of 67

Mashcka [7]

Answer:

Standard Error of the difference = 0.0695

Step-by-step explanation:

Its given that : In a large school district, 16 of 85 randomly selected high school seniors play a varsity sport

$\implies P_1=\frac{16}{85}\\\\n_1=85$

Also, in the same district, 19 of 67 randomly selected high school juniors play a varsity sport

$\implies P_1=\frac{19}{67}\\\\n_2=67$

Now, finding the standard error of the difference :

$\text{Standard Error = }\sqrt{\frac{P_1(1-P_1)}{n_1}+\frac{P_2(1-P_2)}{n_2}}\\\\\implies \text{Standard Error = }\sqrt{\frac{\frac{16}{85}(1-\frac{16}{85})}{85}+\frac{\frac{19}{67}(1-\frac{19}{67})}{67}}\\\\\implies\text{Standard Error = }0.0695$

Hence, Standard Error of the difference = 0.0695

Two factors are multiplied and their product it 34.44. One factor is a whole number. What is the least number of decimal places

Tanya [424]

The answer is 2, because if a number is a whole number, for example 2, you must multiply it by a number with 2 decimals, in this case 17.77, to get 34.44 based on this example.

*There are some cases where this doesn't apply, I think, but it does apply for your question.
