The edge length of cube A is two times the edge length of cube B. How many times greater isthe volume of the cube A than the vol
allsm [11]

Answer:

<h2>8 times greater</h2>

Step-by-step explanation:

The formula of a volume of a cube:

V=a^3

a - edge length

-----------------------------------

The edge length of cube B is a.

The edge length of cube A is 2a.

Calculate the volumes:

V_A=(2a)^3=2^3a^3=8a^3\\\\V_B=a^3

How many times greater is the volume of the cube A than the volume of cube B?

Make the quotient:

\dfrac{V_A}{V_B}=\dfrac{8a^3}{a^3}=8

The number of books borrowed from a library each week follows a normal distribution. When a sample is taken for several weeks, t
Marat540 [252]
\mathbb P(X>250)=\mathbb P\left(\dfrac{X-190}{30}>\dfrac{250-190}{30}\right)=\mathbb P(Z>2)\approx0.0228

Or, if you're familiar with the empirical rule and the basic properties of the normal distribution, you can use the fact that approximately 95/% of the distribution lies within two standard deviations of the mean, or

\mathbb P(|Z|

which means about 5\% of the distribution lies outside this interval, or

\mathbb P((-22))\approx0.05

Because the distribution is symmetric, you have

\mathbb P(-22)
\implies \mathbb P((-22))=\mathbb P(-22)=2\mathbb P(Z>2)\approx0.05
\implies \mathbb P(Z>2)\approx 0.025

Ayana has 220 coins in her piggy bank Of those 40percent are pennies. Out of the coins that are not pennies 25 percent are partn
Rzqust [24]
To find a percent of a number, multiply the percent by the number.

First we find the number of pennies.

40% of 220 =

= 40% * 220

= 0.4 * 220

= 88

88 coins are pennies.

220 - 88 = 132

132 coins are not pennies.

Now we find 25% of 132.

25% of 132 =

= 25% * 132

= 0.25 * 132

= 33

33 coins are partners.

(Did you mean quarters instead of partners?)
