Answer:
There are 9 boys in the choir
Step-by-step explanation:
To solve this, create two equivalent fractions with the information given
boys 3 x
------- = ------ = ------
girls 4 12
Then, cross-multiply
4x = 3(12)
4x = 36
x = 9
Answer:
Concept: Mathematical Analysis
- 2 friends share 56
- 5- 10 dollar bills and 6- one dollar
- We split the bills in half to equate equal change.
- Hence 5 bills ÷2= 2.5 or 25 dollars
- 6 bills÷2= 3 or 3 dollars
- You need to make change for the 10 dollars, break a bill into 5's
Answer:
(-3.5 8.5)
Step-by-step explanation:
Midpoint Formula: (
, 
)
What I did: -10 + 3 = 7, 7 / 2 = 3.5 x = 3.5 | 9 + 8 = 17, 17 / 2 = 8.5
Midpoint = (-3.5, 8.5)
Answer:
6/8
Step-by-step explanation:
probability= required outcome / all possible outcomes
probability = 6/8
For the answer to the question above,
For<span> a) Mean time required for the entire process = (40+25) = 65 minutes
b) Variance time required for the entire process = (2^2+1^2) = 5 minutes
Standard deviation time required for the entire process = sqrt(5) = 2.236 minute.
I hope my answer helped you
