Answer:
3/4
Step-by-step explanation:
Here, we want to calculate the probability that a student selected is a senior student or one that drives to school.
From the table, the number of senior students is 25 + 5 + 5 = 35
So the probability of selecting a senior student is 35/100 = 7/20
Now the probability of selecting a student that drives to school.
The number of students that drive to school is 2 + 13 + 25 = 40
So the probability of a student who drives to school is 40/100
Kindly recall that when we have or and we are dealing with probability, we add the concerned terms together
Thus the probability of randomly selecting a student who is a senior or drives to school = Probability of being a senior + Probability of driving to school = 35/100 + 40/100 = 75/100 = 3/4
Answer:
The correct alternatives
This is a subtraction expression
The correct expression is n minus 31
To evaluate the expression, subtract 31 from 29.
Step-by-step explanation:
Rafael writes an expression to represent “a number, n, decreased by thirty-one.”
First you gotta know what means "decreased by thirty-one". It means that
there exist two numbers where the difference between them is 31.
The number decreased by 31 can be writen as
The expression is therefore
Rafael evaluates the expression for
An=-5n+260
A40=60
So the Awnser is 60
