In a random sample of 200 college students, 110 were females,125 were under the age of 21 years of age, and 45 males were 21 years of ageor older. a student is selected at random from the sample. what is the probability that a female student age 21 or older is selected? a. 15%b. 20%c.85%d.90%

 Option 'a' is correct.                      

Step-by-step explanation:

Since we have given that

Total number of students = 200

Number of females = 110

Number of students under the age of 21 years of age = 125

Number of males under the age of 21 years or older = 45

So,  it becomes

                              Males            Females    Total

21 years                     45                80              125

21 years or older       45                30              75

Total                          90              110               200

So, Probability that a female student age 21 or older is selected is given by

Hence, Option 'a' is correct.                      

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
