Two different ratio are;
Male teacher : Female teacher = 3 : 7
Male teacher : Teacher = 3 : 10
Here,
Number of male teachers = 15
Number of female teacher = 35
We have to find the two different ratio.
What is Ratio?
A ratio is a comparison of two similar quantities obtained by dividing one quantity by the other.
Now,
Number of male teachers = 15
Number of female teacher = 35
Hence, Number of total teacher = 15 + 35 = 50
So, Ratio of Male teacher to Female teacher = 15 : 35 = 3 : 7
And, Ratio of Male teacher to Teacher = 15 : 50 = 3 : 10
Therefore, Two different ratio are;
1. Male teacher : Female teacher = 3 : 7
2. Male teacher : Teacher = 3 : 10

Answer:
Part 1) The system of equations that represent this situation is equal to
b+p=42 and 5b+2p=144
Part 2) 20 binders were sold
Step-by-step explanation:
Let
b -----> the number of binders sold
p -----> the number of pencil pouches sold
Part 1)
we know that
The system of equations that represent this situation is equal to
b+p=42
5b+2p=144
Part 2) How many binders were sold?
we have
b+p=42
p=42-b ------> equation A
5b+2p=144 -----> equation B
substitute equation A in equation B
5b+2(42-b)=144
5b+84-2b=144
3b=144-84
3b=60
b=20 binders
Answer:
mean = 12
Step-by-step explanation:
the mean of a data set is calculated as
mean =
sum = 10 + 11 + 12 + 14 + 12 + 11 + 13 + 12 + 14 + 11 = 120
there are 10 values, so count = 10
Then
mean = = 12
