Answer: A
Step-by-step explanation: Canoe → 8h →X
Rowboat → 5h → Y
Fabrication department has at most 107, which means it need to be <u>less</u> than 107 hours.
This way, the amount of time to fabricate X canoes = 8X plus the amount of time to fabricate Y Rowboat = 5Y must be less than 107.
8X + 5Y < 107
Answer:
70
Step-by-step explanation:
You add all the numbers together and then divided by the number of numbers so
90+80+60+50=
280 divided by 4 is 70
S = 1 + 3 + 5 + ... + 11 + 13 + 15
S = 15 + 13 + 11 + ... + 5 + 3 + 1
==> 2S = (1 + 15) + (3 + 13) + (5 + 11) + ... + (15 + 1)
There are 8 terms in the sum, so
2S = 8 * 16 = 128
S = 128/2 = 64
First lets find the probability of landing tails. Because there is 1 way to get tails and 2 possible outcomes, the probability is 1/2.
Now, lets find the probability of selecting a 9. Since this includes 0, there are 10 possible outcomes and 1 way to get a 9, so the probability is 1/10.
To find them combined, multiply:
1/2 * 1/10
1/20
0.05
Hope this helps!
