gavmur [86]

Answer:

The charges will be the same after 10 miles.

Step-by-step explanation:

Long Beach Towing Company:

Charges $40 plus $5 per mile. So after x miles, the charge will be of:

L(x) = 40 + 5x

Five-Star Towing Company:

Chargers of $70 plus $2 per mile. So after x miles, the charge will be of:

F(x) = 70 + 2x

After how many miles the charges for the two companied will be the same?

This is x for which:

L(x) = F(x)

So

40 + 5x = 70 + 2x

5x - 2x = 70 - 40

3x = 30

x = \frac{30}{3}

x = 10

The charges will be the same after 10 miles.

A Nevada roulette wheel had 38 pockets, labeled as 0 00 1 2 3 ... 35 36. One bet is single number. If you bet $1 on a number (an
slavikrds [6]

Answer:

-0.0526

Step-by-step explanation:

Let X be the random variable denoting the net gain(in dollars) for a single trial(one bet).

Assuming that each number in the wheel is equally likely, probability of the outcome being a victory is \frac{1}{38} and probability of failure is \frac{37}{38}. For a win, X takes value 35 and for a loss X takes value -1. So the model is,

P(X=35) = \frac{1}{38}

P(X=-1) = \frac{37}{38}

P(X=i) = 0 \;if\; i \neq 38, i\neq -1

The mean for one bet is E(X) = \sum xP(X=x) = 35\times\frac{1}{38} - 1\times\frac{37}{38} = -0.0526
