Is x+3=-5y in standard form?

Nope

Step-by-step explanation:

Standard form for a linear equation in two variables is with the terms containing  x  and  y  on the left side of the equation and a number on the right side.

Subtract 3 from both sides.

Add 5y.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead
