Answer:
- Cost of fish = Php. 60, amount of fish = x kg
- Cost of chicken = Php. 120, amount of chicken = y kg
- Budget = at most Php. 1200
a) <u>Required inequality (not a system as only one condition is given):</u>
- 60x + 120y ≤ 1200
<u>Simplified:</u>
- x + 2y ≤ 20
- <em>The graph is attached</em>
b) <u>Verify ordered pair (10, 7):</u>
- 10 + 2*7 ≤ 20
- 24 ≤ 20
False inequality, so this pair is out of solution set
Answer:
0.3 or 30%
Step-by-step explanation:
Since no innocent student will ever be caught, the probability that a student sends an email and/or text message during a lecture AND gets caught is given by the product of the probability of a student sending a message (60%) by the probability of the professor catching them (50%) :
The probability is 0.3 or 30%.
