If all sides of a cube are multiplied by 6, by what factor does the volume increase?

1 answer:

7 0

$\large V=a^3 \\ \\V_{1}=(6a)^3 =6^3*a^3=256a^3\\ \\\frac{V_{1}}{V}=\frac{256 \not a^3^1}{\not a^3^1}= 256\\ \\Answer : \ increase \ the \ volume \ of \ a \ cube \ 256 \ times$

The computer that controls a bank's automatic teller machine crashes a mean of 0.6 times per day. What is the probability that,

professor190 [17]

Answer:

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

Mean of 0.6 times a day

7 day week, so $\mu = 7*0.6 = 4.2$

What is the probability that, in any seven-day week, the computer will crash less than 3 times? Round your answer to four decimal places.

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)$

In which

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-4.2}*(4.2)^{0}}{(0)!} = 0.0150$

$P(X = 1) = \frac{e^{-4.2}*(4.2)^{1}}{(1)!} = 0.0630$

$P(X = 2) = \frac{e^{-4.2}*(4.2)^{2}}{(2)!} = 0.1323$

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0150 + 0.0630 + 0.1323 = 0.2103$

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.

Is this answer true. X is 6.<br><br> X+14>5

Anna35 [415]

Answer:

x is a solution

Step-by-step explanation:

X+14>5

Subtract 14 from each side

X+14-14>5-14

x > -9

Substitute the value in

6 >-9

This is true so x is a solution
