Answer:

a) P) 0.25 = 1/4 both

b) P) 0.75 = 3/4 one

c) P) 0.25 = 1/4 none

Step-by-step explanation:

4 routes to D + H

6 routes to H + S

= D H S

4 | 6

- 2 | -3

= 2 | 3 = route 1 = 2/4 and route 2 = 3/6

= 1/2 route 1 and 1/2 route 2

Answer a ) = 1/2 x 1/2 = 0.25 = 1/4 = 0.25 probability

Answer b) = 1- (1/2 x 1/2) = 1- 0.25 = 3/4 = 0.75 probability

Answer c) = 1/2 x 1/2 = 0.25 = 1/4 = 0.25 probability

A car rental agency charges 34 $ per day to rent a car and 12.95$ per day for a global positioning system (GPS). Customers are

Whitepunk [10]

Answer:

Step-by-step explanation:

A) 34x + 12.95g + 3.60p = b

34x = $ per day to rent

12.95g = $ per day you have GPS

3.60p = $ per gallon

b = total bill

97.35

C) 34(1) + 12.95(1) + 3.60(14) = 97.35

That's how the function would look after you plugged the numbers from the problem in.

I am not 100% if I did this right but it's better than nothing, so you can build off of this.

maks197457 [2]

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Principal (P)= $200

Interst rate (r)= 0.05

Time (t)= 6

First, we need to calculate the total interest using the following formula:

I= P*r*t

I= 200*0.05*6

I= $60

Now, the total debt:

Total debt= P +I

Total debt= 200 + 60

Total debt= $260

The amount of time is takes dora to commute to work is always within 5 minutes of the average number of minutes the commute take

Maslowich

Answer:

The average time to commute to work is 25 minutes.

Step-by-step explanation:

If average time for Dora to commute to work is 5 mins. If she takes 45 mins to get to work then her overall average time to commute to work will change as the average consists of 2 or more figures. The average time to commute to work is 25 mins ((5+45)/2). The average of 5 mins and 45 mins is 25 mins. This is the overall average time she takes to commute to her work.

What is the length of the hypotenuse? If necessary, round to the nearest tenth.

Brut [27]

Answer:

c ≈ 5.5 cm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

c² = 2.4² + 4.9² = 5.76 + 24.01 = 29.77 ( take square root of both sides )

c = $\sqrt{29.77}$ ≈ 5.5 cm ( to the nearest tenth )

How much greater than m2+3mn−n2 is 4m2+5mn+6n2? PLEASE HELP

tiny-mole [99]

Answer:

3m² + 2mn + 7n²

Step-by-step explanation:

Subtract m² + 3mn - n² from 4m² + 5mn + 6n², that is

4m² + 5mn + 6n² - (m² + 3mn - n²)

= 4m² + 5mn + 6n² - m² - 3mn + n² ← collect like terms

= 3m² + 2mn + 7n²
