Step-by-step explanation:
If a boy student was picked, the probability that they passed is 0.25 * 0.4 = 0.1.
If a girl student was picked, the probability that they passed is 0.75 * 0.25 = 0.1875.
Total probability = (0.1 + 0.1875) * 100% = 28.75%.
Answer:
The answer to your question is:
x = 18
m∠ABD = 36°
m∠DBC = 54°
Step-by-step explanation:
m∠ABD + m∠DBC = 90°
2x + 3x = 90°
5x = 90°
x = 90/5
x = 18
m∠ABD = 2(18)
= 36°
m∠DBC = 3(18)
= 54°

Answer:
$ 125,000
Step-by-step explanation:
Given,
The amount of rent = $ 25,000,
The salary of assistant = $ 30, 000
Expenses = $ 20,000,
Also, her best alternative is to work elsewhere and to earn a salary of $50,000 per year.
Thus, the investment in the firm = 25000 + 30000 + 20000 + 50000
= $ 125,000,
Now, if she earns zero economic profit,
Then her revenue = investment
= $ 125,000
