First we want to find how much an individual biscuit costs.
If 5 biscuits costs 30p, then
5 x 1 biscuit = 30p
divide both sides by 5
1 biscuit = 6p
If one biscuit costs 6p, and we want to know how much 7 biscuits cost, then:
7 x 6p =42p
7 biscuits costs 42 p
Answer: 12 sqrt(5)
Explanation:
First simplify:
= Sqrt(45)
= sqrt(9*5) sqrt of 9 is 3 so bring out 3
= 3sqrt(5)
= 2sqrt(20)
= 2sqrt(4*5) sqrt of 4 is 2 so bring that out and multiply it by 2
= 4sqrt(5)
= 5 sqrt(5) is already simplified
= 3sqrt(5) + 4 sqrt(5) + 5sqrt(5)
= 12 sqrt(5)
It all depens on have much is being used per mile
Answer:
18/25 = 72%
Step-by-step explanation:
P(B ∪ F) = P(B) + P(F) - P(B ∩ F)
= 12/25 + 11/25 - 5/25
= 18/25
The probability a randomly chosen student plays either sport is 18/25 = 72%.
