B. 1 13/50
we would convert this by doing 126/100 and then simplifying to 1 26/100 and then 1 13/50
Hi!
The answer is: 15 girls.
__________________________________________________________
Let
x-----> the number of girls
y-----> the number of boys
we know that
- x+y=27, Which is equation A.
- x/y = 5/4
- isolate the variable y
- y=4/5x, Which is equation B.
- 9/5x=27
- x=5x27/9
- 15 Girls.

Answer:
Step-by-step explanation:
Given
Sample Space = 10 to 99
First, we calculate the sample size (n)
Solving (a): P(32)
In 10 to 99, there is only 1 32.
So,
Solving (b): P(Odd)
There are 45 odd numbers between 10 and 99
i.e.
So:
Solving (c): P(Multiple of 5)
There are 18 multiples of 5 between 10 and 99
i.e
Answer:
the mean and median are all equal
Answer:
24 and 21 are the two numbers
Step-by-step explanation:
let n represent the unknown number
let n-3 represent the second unknown number
n+n-3 = 45
2n-3=45
2n=45+3
2n=48
n=48/2
n=24
n-3=21
CHECK: 24+21=45
.˙. the first number is 24 and the second number with a difference of 3 is 21
