10 is proportional, while 11 is not. The answer for 10 is 1.5.
G = 2 inches
The first shape is 6 and 12. The two shapes are similar to each other, so the other shape must be 1 and 2. 6 divided by 6 is 1 so 12 divided by 6 is 2.
Maximum profit due to the feasibility graph....we take where the two lines cross...(6,5). These figures are substituted into the equation and the result is the max profit...
p = 3x + 2y
p = 3(6) + 2(5)
p = 18 + 10
p = 28
Answer:
25.05
Step-by-step explanation:
Given that a random sample of 160 car crashes are selected and categorized by age. The results are listed below. The age distribution of drivers for the given categories is 18% for the under 26 group, 39% for the 26-45 group, 31% for the 45-65 group, and 12% for the group over 65.
<26 26-45 46-65` >65
Observed O 66 39 25 30 160
Expected E 40 40 40 40 160
Chi square
(O-E)^2/E 16.9 0.025 5.625 2.5 25.05
Thus we get chi square test statistic = 25.05
