When multiplying numbers a negative number will make a positive into a negative. Yet if multiplied again by another negative it will cancel out or make it positive again. Seeing as answer c has only one negative it's the correct answer.
What are we supposed to review? There are no specific answers?
Answer:
its choice 2
Step-by-step explanation:
6b is the amount of bracelets that were bought, times the cost of 1 bracelet. 3s is the cost of 1 pair of socks times the amount of socks bought. when you add together 6b+3s it should =300
The standard deviation will be 6816.9645.
<h3>How to compute the standard deviation?</h3>
From the information given, the mean is 74000 and X is given as 60000.
P[(Z < (-60000 - 74000)/SD] = 0.02
Note that 0.02 will be -2.0537 under the normal distribution table.
-14000/SD = -2.0537
SD = -14000/-2.0537
SD = 6816.9645
