Answer:
(a) {(5, 2), (-4, 2), (3, 6), (0, 4), (-1, 2)}
Step-by-step explanation:
The only relation with no repeated x-values is the first one. The first relation is a function.
A = event that a male highschool player plays on a college team
B = event that a female highschool player plays on a college team
C = event that a male college player is drafted by the pro leagues
D = event that a female college player is drafted by the pro leagues
--------------------------------------------
Going from high school to college:
P(A) = 4500/549500
P(A) = 0.0082 <<-- value is approximate
P(B) = 4100/456900
P(B) = 0.0090 <<-- value is approximate
Females have a better chance of playing on college teams (since 0.0090 is larger than 0.0082)
--------------------------------------------
Going from college to the pro leagues:
P(C) = 44/4500
P(C) = 0.0098 <<-- value is approximate
P(D) = 32/4100
P(D) = 0.0078 <<-- value is approximate
Males have a better chance of getting drafted by the pro leagues (since 0.0098 is larger than 0.0078)
Answer:
Step-by-step explanation:
We are asked to find (f+g)(x). The question is essentially asking us to find the sum of f(x) and g(x).
We know that f(x) equals 3x-1 and g(x) equals x+2. Substitute the values of the functions in.
Combine the like terms.
- 3x and x are like terms (both have the variable "x"
- -1 and 2 are like terms (both without variables, also known as constants)
(f+g)(x) is equal to <u>4x+1</u> and the correct answer is A.
C and A are congruent since they are alternate interior angles.
Angles B and A are a linear pair. Linear pairs are supplementary as well. Since we know A is 44, all the have to do is 180-44 . That equals 136.
In short, A=44 and B=136
