Answer & Step-by-step explanation:

(x² - 5x)(2x² + x - 3)

Multiply each term from the first expression into the second expression.

2x⁴ + x³ - 3x² - 10x³ - 5x² + 15x

Combine like terms.

2x⁴ - 9x³ - 8x² + 15x

So, after you multiply the expressions, your answer will be 2x⁴-9x³-8x²+15x.

Important Characteristics Quiz The probability of success in each of the 58 identical engine tests is p = 0.92. What is the mean

Maru [420]

Answer: The mean of this binomial distribution is 53.36.

Step-by-step explanation:

We know that , the mean of this binomial distribution is given by :_

$\mu = np$

, where n = sample size or the number of possible trials .

p = probability of getting success in each trial.

We are given that , the probability of success in each of the 58 identical engine tests is p = 0.92.

i.e. n= 58

p=0.92

Then, the mean of this binomial distribution = $58\times0.92=53.36$

Hence , the mean of this binomial distribution is 53.36.
