Answer:
2 hours
Step-by-step explanation:
Let's denote the amount of time we need to find out, t.
=> 600 + 50t < 500 + 100t
or 600 - 500 < 100t - 50t
or 100 < 50t
or 100/50 < t
or t > 2
=> After 2 hours, company B will be cheaper option than company A
If you would like to know how many cups of flour are needed to make 6 servings, you can calculate this using the following steps:
3 cups of flour ... 8 servings
x cups of flour = ? ... 6 servings

Since you cannot appoint the same person twice, the probabilities are <u>without replacement.</u>
(a)Probability that both appointees are men.

(b)Probability that one man and one woman are appointed.
To find the probability that one man and one woman are appointed, this could happen in two ways.
- A man is appointed first and a woman is appointed next.
- A woman is appointed first and a man is appointed next.
P(One man and one woman are appointed)

(c)Probability that at least one woman is appointed.
The probability that at least one woman is appointed can occur in three ways.
- A man is appointed first and a woman is appointed next.
- A woman is appointed first and a man is appointed next.
- Two women are appointed
P(at least one woman is appointed)

Step-by-step explanation:
-18 (Negative Eighteen) = A
29 (Positive Twenty Nine) = B
11 (Positive Eleven) = C
First, make A positive, and add C to it. You get B.
Now here is the equation:
-18 + (18 + 11)
-18 + (29)
11
