a. What is the probability that the firm will make at least one hire?
b. Find the expected value and the standard deviation of the number of hires. (Round your final answers to 2 decimal places.)

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

range is infinite on both x and y axis positive and negative
