Answer: Is this math or science?
Step-by-step explanation:
Cuando multiplicas un número positivo y un número negativo, la respuesta siempre será negativa:
4(3) = 12
4(-3) = -12
<span>Para multiplicar fracciones, simplemente multiplique los numeradores y los denominadores en línea recta:
5/4 * 4/7 = 20/28 = 10/14 = 5/7

He ran 8.6........ mikes per minute, I just divided 104÷12=8.66666666666666, but all if those sixes don't matter.
I hope this helps!
Answer:
<h3>7/10</h3>
Step-by-step explanation:
Using set notation;
Let n(U) be the total number of students in the school = 100%
Let n(M) be the percentage of male students in the school = 56%
Let n(A) be the percentage of students between the ages of 18 and 20 (A) in the school = 32%
Let n(M∩A) be the percentage of both male and between the ages of 18 and 20 = 26%
The n(MUA)' be the number of female students in the school
Using the formula to get n(MUA)
n(MUA) = n(M)+n(A)- n(M∩A)
n(MUA) = 56+32-26
n(MUA) = 62%
Also, n(U) = n(MUA)+n(MUA)'
100 = 62+n(MUA)'
n(MUA)' = 100-62
n(MUA)' = 38%
This means that there are 38% of students in the school.
The probability of choosing a random student who is a female or between the ages of 18 and 20 is expressed as;
P(F or A) = P(F)+P(A) (mutually exclusive event i.e both cannot occur at the same time)
P(F or A) = 38/100 + 32/100
P(F or A) = (38+32)/100
P(F or A) = 70/100
P(F or A) = 7/10
Hence the probability of choosing a random student who is a female or between the ages of 18 and 20 is 7/10.
