Answer:
46/55
Step-by-step explanation:
A B C Total
Male. 2 19 7 28
Female. 4 9 14 27
Total. 6 28 21 55
Total number of students = 55
Pr of picking a female = number of females / total number
= 27/55
There are 27 females and 28 people got a B
Number of females or those who got a B = 27 + 28 = 55
Subtract off 9 females who got B to help correct for double counting . We have 55 - 9 = 46
This means there are 46 people who either got a B, are females or are females who got a B
Pr(female or got a B) = number who are females or got a B / total number
= 46/55
It’s the last one because that one has no repeats. One outcome can not be listed twice
B
To find the x- intercepts let f(x) = 0 , that is
(x + 1)(x + 4) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x + 1 = 0 ⇒ x = - 1
The x- intercepts are (- 4, 0 ) and (- 1, 0 )
He still has $187 for his students
17X16=272 -85= 187 Simple as that!
