Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclis
koban [17]

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, d_{45 \ minutes} is given as follows;

45 minutes = 3/4 hour

d_{45 \ minutes}  = (12 + b) × 3/4 = (3/4·b + 9) miles

The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.

As a company manager for the Quick Money Business there is a 0.40 probability that you will be promoted this year. There is a 0.
Maslowich

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

P(R | P) = \dfrac{P(P \& R)}{P(P)} = \dfrac {0.25}{0.4} = 0.625

Probability of getting raise when you get promoted = 0.625.

Now we find the  probability of getting a raise,

P(P\ or\ R) = P(P) + P(R) - P(P \& R)\\\0.72 = 0.4 + P(R) - 0.25\\P(R) = 0.72 - 0.4 +0.25\\P(R) = 0.57

So, the probability of getting raise = 0.57.

In a large bag of candy, each of the 5 colors ( red, orange, yellow, blue, and green) occurs with the same probability. You reac
kirill [66]
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

Which expression is equivalent to the radical expression shown below when it is simplified?
babymother [125]

Answer:

\sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}

Step-by-step explanation:

We need to solve the expression

\sqrt{\frac{3}{64} }

We know that \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}

and 64 = 8*8

Solving we get

=\frac{\sqrt{3}}{\sqrt{64}}\\=\frac{\sqrt{3}}{\sqrt{8*8}}\\=\frac{\sqrt{3}}{\sqrt{8^2}}\\=\frac{\sqrt{3}}{8}

So \sqrt{\frac{3}{64} } in simplified form is \frac{\sqrt{3}}{8}
