I believe it's the first one
Answer:
A. 3 3/4 quarts
B. 7 1/2 pints
Step-by-step explanation:
1 gallon=4 quarts
1 quart=2 pints so
1/2 gallon= 2 quarts and
1/4 gallon=1 quart
1+2+3/4=
3 3/4 quarts
(3 3/4)2=
7 1/2 pints
If p(4) = 16 then
n*4² + 8 = 16
16n + 8 = 16
16n = 16 - 8
16n = 8
n = 8/16 = 0.5
If n = 0.5 then
p(-3) = 0.5*(-3)² + 8
p(-3) = 0.5 * 9 + 8
p(-3) = 4.5 + 8
p(-3) = 12.5

Answer:
Expected value of profit is ≅ $15.80
Step-by-step explanation:
from the Question,
Let the variable X represents the expected value of profit. X is called as random variable because picking a number from 000-999 digits is a Random process.
P(win) =
So, P(lose) =
Suppose that,
we really want to win this lottery. so we can go to the store and spend $1000 to buy all ticket (from 000 - 999). This would ensure your winning of $500 with one of the tickets (for a $499 profit), but the other 999 would be losers (for a $999 loss).
What would be your average winnings on a per-ticket basis?
∑
=
Here,
Standard deviation of the expected winnings
∑
= ∑
Taking square root of the variance to get the standard deviation:
SD(x) =
≅ $15.80
Hence
The expected value of profit is ≅ $15.80
<em />It is (4,0). If you plug in 4 for x and 0 for y, then both inequalities will be true.
