<span>The quotient of two numbers is negative. It must be true that B. one of the numbers is negative.
If neither number is negative, then their quotient will be positive, because both numbers are positive. If both numbers are negative, then their quotient will also be positive.
But since B is correct, their quotient will be negative.
For example: -9/3 = -3</span>

Answer: 0.8926
Step-by-step explanation:
Given : A shipment of 50 inexpensive digital watches, including 10 that are defective.
The probability that a digital watch is defective 
Sample size : n=10
Also, they reject the whole shipment if 1 or more in the sample are found defective.
Using the binomial probability formula :

Let x be the random variable that represents the number of defective watches.
The probability that the shipment will be rejected :-

Hence, the probability that the shipment will be rejected = 0.8926
Answer: (10 - 6i)/5
(x + yi) + (4(x + yi) + 6i) = 10
⇔ 5(x + yi) + 6i = 10
⇔ 5(x + yi) = 10 - 6i
⇔ x + yi = (10 - 6i)/5
Step-by-step explanation:
