Joe paid $25 for a $40 sweater, so we need to know what percent of 40 25 is.
25/40 is .625, or 62.5%. Subtract that from 100% and you get 37.5%, the answer to the question.

15% off would make the sweater $31, instead of $25.

Solve the system of equations and choose the correct ordered pair.

nasty-shy [4]

The answer is D

Because if you replace the variables just by testing them they give the answer as X=-3 and Y=3.
In which replacing:
3(-3)+5(3)=6
and with the other equation we've got:
4(-3)+2(3)=-6
so they comply with the required to be the correct answer, even though you can make a system of equation.

A basket contains 8 green apples, 11 red apples, 5 nectarines, and 12 oranges. Mark randomly chooses a piece of fruit, eats it,

bogdanovich [222]

Answer:

3.17% probability of selecting first a green apple and then a nectarine.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

P(a green apple then a nectarine)

This is the probability of selecting first a green apple and then a nectarine.

Initially, there are 8+11+5+12 = 36 fruits, of which 8 are green apples. So 8/36 probability of choosing a green apple.

Now, there are 35 fruits, of which five are nectarines. So 5/35 probability of choosing a nectarine.

Then

$p = \frac{8}{36}\times\frac{5}{35} = 0.0317$

3.17% probability of selecting first a green apple and then a nectarine.
