Identify the expression for calculating the mean of a binomial distribution

TEA [102]

Option C: np is the expression used for calculating the mean of a binomial distribution.

Explanation:

From the options, we need to determine the expression that is used for calculating the mean of a binomial distribution.

Option A: npq

The variance of the binomial distribution can be calculated using the expression npq.

Hence, Option A is not the correct answer.

Option B: $\sqrt{npq}$

The standard deviation of the binomial distribution can be calculated using the expression $\sqrt{npq}$

Hence, Option B is not the correct answer.

Option C: np

The mean of the binomial distribution can be calculated using the expression np

Hence, Option C is the correct answer.

Option D: $\sum\left[x^{2} \cdot P(x)\right]-\mu^{2}$

The mean of the binomial distribution cannot be determined using the expression $\sum\left[x^{2} \cdot P(x)\right]-\mu^{2}$

Hence, Option D is not the correct answer.

Which process will create a figure that is NOT congruent to the figure shown? Every point is moved 3 units to the right. Every p

sesenic [268]

Answer:

Every point is moved so that it is 2/3 as far from the y-axis

Step-by-step explanation:

Translation and reflection are "rigid" motions. They do not change the size or shape of the figure, so the resulting figure will be congruent with the original.

Dilation by a factor of 2/3 changes the size, so will not result in a congruent figure.

_____

Here the dilation is in the x-direction only. It is not a transformation we usually are interested in.

Fill in the missing number to complete the factorization:

IrinaVladis [17]

The last terms must multiply to the last terms (confusing)

example

if ax^3+bx^2+c+d=(ex+f)(gx+h)(jx+k) then
d=fhk

so

70 is last term
we got 2 and 5
2*5*?=70
10*?=70
divide by 10
?=7

the missing number is 7
