Insurance providing salary to employees injured while working.
Sutract 2x from both sides
-12x-6=18
Add 6 to both sides
-12x=24
Divide both sides by -12
x=-2
Final answer: x=-2
Answer: look at the picture
Step-by-step explanation: Hope this help :D
The answer to the question should be 4 candles and the first candle would not still be lit.
Using the binomial distribution, it is found that about 75 batteries each day are defective.
For each battery, there are only two possible outcomes, either it is defective, or it is not. The probability of a battery being defective is independent of any other battery, hence the <em>binomial distribution</em> 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:
In this problem:
- 3 out of 20 batteries are defective, hence p = 3/20 = 0.15.
- Each day, 500 batteries are produced, hence n = 500.
Then:
About 75 batteries each day are defective.
