1) neither
2) geometric sequence
Answer: D) 0.733.
Step-by-step explanation:
Let C denotes the number of employees having college degree and S denote the number of employees are single.
We are given ,
Total = 600 , n(C)=400 , n(S)=100 , n(C∩S)=60
Then,

Now, the probability that an employee of the company is single or has a college degree is

Hence, the probability that an employee of the company is single or has a college degree is 0.733
One fifth of a number n is equal -7 as an equation would look like this:
1/5 n = -7 / * 5 (both sides)
n = -35
So if number n equals -35, then it's true that 1/5n equals -7.
