X + 9 = 2x - 3
<u>-x -x </u>
9 = x - 3
<u> +3 +3</u>
12 = x
The correct answer is choice d because you would divide x by 2 to get 70. then you do the same with y so 35/2 = 17.5
Answer:

Step-by-step explanation:
The given complex number is

The polar form of this complex number is;
, where


and

This implies that;
to the nearest degree.
Hence the polar form is

Considering that for each item, there are only two possible outcomes, and the probability of an item being defective is independent of any other item, the binomial distribution is appropriate.
<h3>What is the binomial probability distribution?</h3>
It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.
