Hope this helps!
1 out of 12 can be written as 1/12
now multiply 456 by 1/2
this is the same as dividing 456 by 12
456/12 = 38 students share a locker
Answer:
A. 64
Step-by-step explanation:
The shoes are 80 dollars. We get a 20% discount
Discount = 80*20%
= 80*.20
=16
The sales price = original price less the discount
= 80 -16
= 64
Answer:
31.3%
Step-by-step explanation:
Start by doing the binomial expansion of (x+y)^6 where x represents success. This is
(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)
We are interested in the x^3y^3 term which represents exactly 3 successes. Since the probability of success and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is
20/64 = .3125 which is 31.25% Rounding yo the nearest tenth gives us
