Answer:
x=31
y=15
Step-by-step explanation:
let x and y be the 2 part
x+y=46
x-2y=1 ⇒ x=1+2y
substitute :
1+2y+y=46
3y=46-1
3y=45 ⇒ y=45/3=15
x-2y=1
x-2(15)=1 ⇒ x=1+30 ⇒x=31
x= 2 times y(15)+1
y=15
31+15=46

Answer:
Step-by-step explanation:
GIVEN: The mathematics department of a college has male professors, female professors, male teaching assistants, and female teaching assistants.
TO FIND: If a person is selected at random from the group, find the probability that the selected person is a professor or a male.
SOLUTION:
Total employees in mathematics department
Total males in mathematics department
Probability that selected person is a male
Total professor (male+female)
