Computer chips often contain surface imperfections. For a certain type of computer chip, 9% contain no imperfections, 22% contain 1 imperfection, 26% contain 2 imperfections, 20% contain 3 imperfections, 12% contain 4 imperfections, and the remaining 11% contain 5 imperfections. Let X represent the number of imperfections in a randomly chosen chip. Is X discrete or continuous

The random variable X is a discrete random variable.

Step-by-step explanation:

Let X = number of surface imperfections on computer chips.

The probability distribution of the number of surface imperfections on computer chips is:

X    P (X)

0    0.09

1     0.22

2    0.26

3    0.20

4     0.12

5     0.11

The random variable X is a discrete random variable.

This is because a discrete random variable has a finite number of possible values with probability of each value ranging from 0 to 1.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4
