Answer is C because it is proportion.
Answer: x < -9
Step-by-step explanation:
-8x > 72
x < -9 when dividing a negative number in an inequality, change the sign to opposite.
the number are less than -9.

C
Step-by-step explanation:
Here is the complete question
ack wants to fined out which can pineapples is the best buy. He has a choice of four different -sized cans. Which can has the lowest unit price per ounce?
A. 8 ounce for $ 1.44
B. 6 ounce for $ 1. 14
C. 18 ounce for $ 2.88
D. 10 ounce for $ 1.62
unit price = price / total ounces
$1.44 / 8 = $0.18
$1.14 / 6 = $0.19
$2.88 / 18 = $0.16
$1.62 / 10 = 0.162
the lowest is 18 ounce for $ 2.88
We need to correctly choose exactly 4 out of the 6 drawn numbers.
Apply hypergeometric distribution:
a=number of correctly chosen numbers = 4
A=number of correct (drawn) numbers = 6
b=number of incorrectly chosen numbers = 2
B=number of undrawn numbers = 44-6 = 38
Then by the hypergeometric distribution
P(a,b,A,B)
=C(A,a)C(B,b)/C(A+B,a+b) [C(n,r)=combination of r objects taken out of n]
=C(6,4)C(38,2)/C(44,6)
=15*703/7059052
= 10545/7059052
= 0.001494 (to the nearest millionth)
Answer: probability of winning third prize is 10545/7059052=0.001494
