Step-by-step explanation:
difference=28
other number=11
so:
11+28=39
39 is your other number

Answer: 30 ft
Step-by-step explanation:
Cross multiply:
6 : 3.5
x : 17.5
Then divide 105 with 3.5x.
105/3.5x = 30
It might be step 4 where it got dropped by step 3
Given:
The number of male professors = 15.
The number of female professors = 9.
The number of male teaching assistants = 6.
The number of female teaching assistants = 12.
A person is selected randomly from the group.
Required:
We need to find the probability that the selected person is a professor or a male.
Explanation:
The total number of people in the group = 15+9+6+12 = 42
n(S) =The total number of people in the group

Let A be the event that the selected person is a professor or a male.
The number of people who are professors or male = 15+9+6 = 30
n(A)= The number of people who are professors or male.

Let P(A) be the probability that the selected person is a professor or a male.



Final answer:
The probability that the selected person is a professor or a male is 5/7.
