Simplify 7p+2p-9p anyone know need answer asap
step-by-step explanation: the budget of $500 is basically $150 plus the $5.50 and each student plus the 150 equals $500.
to find the percentage, we take the tax over the subtotal
percentage = tax/subtotal
multiply by 100% to change from decimal to percent form
probability that both cans were regular soda =
we are given 12 total number of cans; 4 cans have been accidentally filled with diet soda.
probability that first can is a regular soda:
outcome that first can is a regular soda will give us the number of regular soda available which are 4
using formula of probability
total possible outcomes are, n(total) = 12
desired outcome: 4 (cans of regular soda)
p(1st can) = =
probability that 2nd can is a regular soda:
as we have already taken a can of regular soda from the pack, the total soda in the pack now 11 and the regular soda left are 3.
total possible outcomes are, n(total) = 11
desired outcome: 3 (cans of regular soda as one has already been taken)
p(2nd can) =
probability that both cans are regular soda:
p(both) = p(1st can) × p(2nd can)
