Drag numbers to use a negative factor to factor the expression -59 + 15h - 25. Numbers may be used once, more than once, or not

koban [17]

Answer:

$-5(g - 3h + 5)$

Step-by-step explanation:

Given

$-5g + 15h - 25$

Required

Factor using a negative factor

Express each term as a factor of -5

$-5*g - 5*-3h - 5 * 5$

Factor out -5

$-5(g - 3h + 5)$

Hence:

The factored form of $-5g + 15h - 25$ is $-5(g - 3h + 5)$

A light bulb factory produces 922 light bulbs every hour. Approximately 3.34% of the light bulbs are defective, and do not work.

Nikitich [7]

Answer:

The value is $\sigma = 5.46$

Step-by-step explanation:

From the question we are told that

The number of light produced in an hour is n = 922

The proportion of the bulb that are defective is p = 0.0334

Generally given from the question that we should use binomial distribution it then means that the standard deviation is mathematically evaluated as

$\sigma = \sqrt{ n * p (1-p)}$

=> $\sigma = \sqrt{ 922 * 0.0334 * (1-0.0334)}$

=> $\sigma = 5.46$
