Using the binomial distribution, it is found that they would expect to find 240 dead batteries among the entire 12,000.
For each battery, there are only two possible outcomes, either it was dead or it was not. The probability of a battery being dead is independent of any other battery, hence the binomial distribution is used to solve this question.
<h3>What is the binomial probability distribution?</h3>
It is the <u>probability of exactly x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
In this problem, we have that:
- One in 50 batteries are dead, hence p = 1/50 = 0.02.
- There is a total of 12,000 batteries, hence n = 12000.
Then:
E(X) = np = 12000(0.2) = 240
They would expect to find 240 dead batteries among the entire 12,000.

Answer:
False equation: -2|8 - 6| - 6 = -10
Step-by-step explanation:
-2|8 - 6| - 6 = -12 True or false?
-2 | 2| - 6 = -12 Substract 8 - 6 = 2
-2 × 2 - 6 = -12 |2| = 2 absolute value of 2 is 2
- 4 - 6 = -12 -2 × 2 = -4 ( negative times positive = negative)
-10 = -12 False
Answer:
Shade in the following boxes: 24, -9.0, 1, 0, and 35
Step-by-step explanation:
Integers are whole numbers (not fractions or decimals) that can be positive or negative.
Both are correct, since 4/6 is simplified to 2/3.
