Out of 124 students, only 31 students are taught to buy their lunches in the cafeteria.
<u>Step-by-step explanation:</u>
It is given that,
The 25% of 124 students are taught to buy their lunches in cafeteria.
Therefore, the total number of students taught to buy their lunches in cafeteria is 25% of 124.
<u>To find the number of students who are capable to buy lunches in cafeteria:</u>
- Replace the % symbol into the numeric form.
- The % is represented by 1 ÷ 100.
The 25% of 124 students is written as,
⇒ 25×(1/100)×124
⇒ (1/4)×124
⇒ 31
The number of students taught to buy lunches in the cafeteria out of 124 students is 31 students.
X^2+3x+1+4x-1+2x^2
Combine like terms:
x^2+2x^2=3x^2
3x+4x=7x
1+(-1)=0
Solution:
3x^2+7x
All you can do here is simplify it
Answer:
3/5
Step-by-step explanation:
There are 20 balls, numbered 1 through 20.
Of these, 10 are even, 4 are less than five, and 2 are both even and less than 5.
So the probability is:
P(even or <5) = P(even) + P(<5) − P(even and <5)
P(even or <5) = 10/20 + 4/20 − 2/20
P(even or <5) = 12/20
P(even or <5) = 3/5
