Mathematics
1 answer:
TEA [102]3 years ago
8 0

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.

<u>Option A: npq</u>

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

Hence, Option A is not the correct answer.

<u>Option B: </u>\sqrt{npq}<u></u>

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

Hence, Option B is not the correct answer.

<u>Option C: np</u>

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

Hence, Option C is the correct answer.

<u>Option D</u>: \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.

If f(x) = 3x + 2, then find the value of x such that f(x) = -4. A. -14 B. -10 C. -2 D. 14
erma4kov [3.2K]

Answer:

C.

Step-by-step explanation:

f(x) = 3x+2

f(x) = -4

-4 = 3x+2

-4-2 = 3x

-6 = 3x

-6/3 = x

-2 = x

x = -2
