12 + 20 + 17
= 49
So there are 49 marbles, and 12 of them are red
so that mean's there will be a 24.49% of picking a marble

Well maybe 100% because there is no numbers.

Answer:

Step-by-step explanation:

The sides of the base are each 5 inches. We see 4 right angles so that we are dealing with a square.

The triangles look to be isosceles. In any event there are 4 of them. So the answer is the 3rd one down.

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.

What is the constant of proportionality for m=32•g

lina2011 [118]

Answer:

∴ Constant of Proportionality is 32

Step-by-step explanation:

Here Given;

$m=32\times g$ (equation-1)

$\frac{m}{g}=32$ (equation-2) (divide with 'g' on both side)

We know,

The Constant of Proportionality equation is given;

$y=k\times x$ (equation-3)

Where 'k' is known as Constant of Proportionality.

Comparing equation-1 and equation-3;

$y=m$ and $x=g$

Now equation-2 become;

$k=\frac{y}{x}$

Plug $y=m$ and $x=g$ in above equation;

$\frac{m}{g}=k$ (equation-4)

By comparing equation-2 and equation-4;

$k=32$

So Constant of Proportionality is 32
