Answer:60.2857143
Step-by-step explanation:
876
any number between 800-899 and 1800-1899 and so on will be fine as the 8 is in the hundredths place
Simplify by dividing 19 by 4
the closest we can get is 16/4=4 and the remainder 3/4
so the piano is 4 and 3/4 foot long which is less than 5 so it will fit
Answer:
7 x + 3 +24
Step-by-step explanation:
The answer is 7 x + 3 =24 because its a problem solving
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.
