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.
Answer:
4180 to 5230$
Step-by-step explanation:
1. Lets find the expenses she has to make -> 4*90+660=1020$(4 new tires + other expenses)
2. As her income is not set strictly we can guess the range she can save(More accurate calculations depends on her strict incomes). We have 5200-1020=4180$(if she gets paid 5200$) and 6250-1020= 5230$(if she gets paid 6250$).
3. So the range of savings vary from 4180 to 5230$$.
0.504854369 as a percentage would be 50.4854369%
easiest way to remember: a percentage is a decimal rounded 2 decimal places to the right
rounded to the nearest tenth, the percentage will be 50.5%

Answer:
10 years ago
Step-by-step explanation:
Let x be the number of years ago
x years ago,
Sonu's grandmother was 80 - x
Sonu was 20 - x
x years ago,
the grandmother was 7 times as old as Sonu
80 - x = 7(20 - x)
80 - x = 140 - 7x
6x = 60
x = 10
