Do you have any numbers on the pop. Or speed?
we are given
62% of the students take math
so,
49% take science
38% take both science and math
n(M∩S)=38
now, we can use union formula
n(M∪S)=n(M)+n(S) -n(M∩S)
now, we can plug values
and we get
n(M∪S)=62+49 -38
n(M∪S)=73
so,
the percentage takes at least one science or math course is 73%..........Answer
Answer:
1.81,2.54,3.77
Total
8.12
Step-by-step explanation:
To find the tax, multiply the original amount by the tax rate
tax
25 * 7.25%
25 *.0725
Rounding to the nearest cent
1.81
35 * 7.25%
35 *.0725
Rounding to the nearest cent
2.54
52 * 7.25%
52 *.0725
Rounding to the nearest cent
3.77
Total for all three
1.81+2.54+3.77=8.12
Answer:
x=2
Step-by-step explanation:
combine like terms= -7x -5x = -12x
-12x + 8 = -16
subtract 8 from both sides
-12x = -24
divide both sides by -12
x = 2
Step-by-step explanation:
r+(−8)=10
r - 8 = 10
r = 10 + 8
r = 18
(substract 8 from 1 side and add it to the other side )
