Answer: a) see image (below)
b) S ∩ M = 237
c) S U M = 598
<u>Step-by-step explanation:</u>
b) Total students = 685
Not sports or music = 87
Sports Total = 385
Music Total = 450
Both Sports and Music is their intersection:
S ∩ M = S + M + N - T
= 385 + 450 + 87 - 685
= 237
c) Sports only = S - (S ∩ M)
= 385 - 237
= 148
Music only = M - (S ∩ M)
= 450 - 237
= 213
Sports OR Music is their union:
S U M = S + M - (S ∩ M)
= 385 + 450 - 237
= 598
The three is in the tenths place so the numerator is 3 and the denominater is 10 so the equivalent fraction would be 3/10
A becuase i worked it out and i got that so im really confident
Divide as usual
Position the decimal point in the result directly above the decimal point in the dividend.
Check your answer: Use the calculator and multiply the quotient by the divisor.
10x+4
3x+4+7x
=10x+4
Add the numbers with the same variable
