1 out 12 is the probability of it being raspberry-filled.
Answer:
-4
Step-by-step explanation:
I got it wrong and it showed me the answer.
S=2(4x+2x)+4x^2=4x^2+12x
4x^2+12x=7
4x^2+12x-7=0
D=12^2-4x4x(-7)=256
X1=(-12-16)/(2x4)=-3.5 impossible
X2=(-12+16)/(2x4)=0.5
A
Answer:
D
Step-by-step explanation:
3 - 7 = -4 and 3(3) + 2(-7) = -5, so D is the only choice that is correct for both inequalities.
A) The average market price is (12 + 8 + 10 + 13 + 14 + 8) / 6 = $10.83
b)
The total amount spent was: 12*8 + 8*12 + 10*10 + 13*7 + 14*7 + 8*12 =
$577. The total number of shares was: 8 + 12 + 10 + 7 + 7 + 12 = 56.
Therefore the average price per share was $577 / 56 shares =
$10.30/share.
c) Since the cost per share in June was $12, and her average cost was $10.30, dollar-cost averaging worked in her favor since her average cost was lower.
