Find the volume of the solid. When appropriate, use π=3.14 and round your answer to the nearest hundredth.

Elenna [48]

Answer:

3179.25

Step-by-step explanation:

Hello!

To find the volume of a cylinder we use the equation

$V = \pi r^{2} h$

V is volume

r is radius

h is height

Put in what we know. It is says to use pi as 3.14

$V = 3.14 * 7.5^{2} *18$

Solve

V = 3.14 * 56.25 * 18

V = 3179.25

Hope this Helps!

What is the measure of ∠x?

Dima020 [189]

The angle is a complementary angle so both angles add up to 90 degrees

Therefore set your equation equal to 90 to find angle of x

53+x=90

Subtract 53 from both sides

X= 37 degrees

In a normally distributed data set a mean of 55 where 99.7% of the data fall between 47.5 and 62.5, what would be the standard d

NeX [460]

Given that normally distributed data set has a mean of 55 and 99.7% of data fall between 47.5 and 62.5.

Let s be the standard deviation of data set.

Since 99.7% data fall within 3 standard deviations of mean, z-value for 47.5 and 62.5 has an absolute value of 3.

That is |z|=3

But z= $\frac{x-mean}{standard deviation}$

Let us plugin x=47.5 and mean =55 and equate it to 3.

That is $|\frac{47.5-55}{s}| = 3$

$|\frac{-7.5}{s} | =3$

Since x is always positive ( being standard deviation), $|\frac{-7.5}{s} | = \frac{|-7.5|}{s} = \frac{7.5}{s}$

Hence $\frac{7.5}{s}= 3$

$s=\frac{7.5}{3} = 2.5$

We will get same value with 62.5 as well.

Hence standard deviation of data set is 2.5.

Explain why 3(5x) is not equivalent to (3*5)(3*x).

Nookie1986 [14]

Wow. Ok, really simple, honestly. Because 3(5x) = 15x. (3*5)(3*x) = 3*5 = 15*3 = 45x. Therefore, 15x and 45x do not correspond to each other at all, meaning that 3(5x) is not equivalent to (3*5)(3*x)!!!
