Answer and explanation:

There's 3 one dollar bills

2 five dollar bills

and 2 ten dollar bills

and 1 twenty dollar bill

3+2+2+1=8

Part A: The probability of selecting 5 is 2/8 and the probability of selecting 10 is also 2/8 and both of them are the same, 1/4.

Part B: The probability of selecting a one dollar bill is 3/8 and the probability of selecting a twenty dollar bill is 1/8 because there are 3 one dollar bills in 8 bills and 1 twenty one dollar bill in 8 bills only.

from 2002 to 2012, the number of a particular make of cars sold at a dealership yearly declined to 500. The number is expected t
Alinara [238K]
To determine the number of cars that will be sold by the year 2020, we will use the equation,

     N = (N1)(1 - r)^(t)

where N1 is the starting number of cars, r is the rate of the decrease, and t is the number of years from 2012. Substituting the konwn values,

   N = (500)(1 - 0.028)^(8)
    N = 398.38

The closest integer to the calculated value is 398. Thus, the answer is 398 cars.

IM SORRY BUT I NEED THIS QUESTION TOO ASAP PLEASE
Paraphin [41]

Using proportions, it is found that the amount of the novel she would have read is:

D. 14/15.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

She has finished 5/6 of the novel, and will have read more 1/10 in the next two days, hence the total amount read is given by:

\frac{5}{6} + \frac{1}{10} = \frac{25 + 3}{30} = \frac{28}{30} = \frac{14}{15}

Hence option D is correct.
