What is the probability that a student with a GPA below 3.0 does not enjoy school?
Only 15/60 below 3.0 enjoy school.
Rounded, that equals 25%.
Therefore, there is a 75% probability that a student with a GPA below 3.0 does not enjoy school.
So the total amount of marbles is: 20+12=32
there are 20 pink marbles
20/32 = 10/16 = 5/8 (simplified)
The answer is D. If you substitute those values for n, you should be able to find that 4 makes the expression equal to 6.
Multiply all terms by 15
3x+3x= 10x+30
Combine like terms
6x=10x+30
Subtract 10x from both sides
-4x=30
Divide both sides by -4
x= -7.5
Final answer: -7.5
Function: 12+0.5x
12+0.5x=18.5
0.5x=6.5
x=13 days
