Each bag of Skittles is supposed to have at least 30 Skittles. A machine that fills bags has a 0.005 probability of under fillin

telo118 [61]

Answer:

The standard deviation for the number of bags that are underfilled is 2.236.

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. The variance is the same as the mean, which mean that the standard deviation is the square root of the mean.

In this question:

Expected number of underfilled bags in a sample of n bags is:

$\mu = 0.005*n$

1000 bags, so

$\mu = 0.005*1000 = 5$

Standard deviation $S = \sqrt{5} = 2.236$

The standard deviation for the number of bags that are underfilled is 2.236.

Twelve cans of peaches are placed into each box. Write a function rule for the number of boxes needed for c cans. How many boxes

Mars2501 [29]

C = # of cans

b = # of boxes

C | B

12 | 1

24 | 2

36 | 3

12b = C

12b/12 = 1440/12

b = 120 boxes

for 1440 cans.

When you ARE NOT given the vertex from a graph, how do you find the k value?

Simora [160]

Answer:

$f( - \frac{b}{2a} )$

Step-by-step explanation:

When you not given the vertex form, the you are given the standard form:

$f(x) = a {x}^{2} + bx + c$

The value of k, is the y-value of the vertex of the function.

To find the value of k, you plug in

$x = - \frac{b}{2a}$

In order works, you evaluate

$f( - \frac{b}{2a} )$

This will give you the k-value
