Answer:
The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles
Step-by-step explanation:
The given parameters are;
The distance between the two cyclist when they begin biking away from each other = 7 miles
The first cyclist's speed = 12 miles per hour
The second cyclist's speed = 12 + b miles per hour
Therefore, we have;
The equation for distance covered, d = Speed × Time
The distance covered by the second cyclist in 45 minutes, 
is given as follows;
45 minutes = 3/4 hour
= (12 + b) × 3/4 = (3/4·b + 9) miles
The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.
Answer:
Probability of getting raise when you get promoted = 0.625
Step-by-step explanation:
We have to find the probability of getting a raise. So,
Promotion = P, Raise = R
First we find if you get the promotion, what is the probability that you will also get a raise
Probability of getting raise when you get promoted = 0.625.
Now we find the probability of getting a raise,
So, the probability of getting raise = 0.57.
If each color appears with the same probability, then there is a 1/5 chance to pick any color.
Since picking orange and picking red are mutually exclusive (if you pick orange you can't also pick red), then P(orange or red) is just the sum of their two probabilities.
1/5 + 1/5 = 2/5 or 0.4
