A businessman bought a car dealership that is incurring a loss of $500,000 a year. He decided to strategize in order to turn the

business around. In addition to the $500,000 annual loss, his fixed cost for running the dealership on a monthly basis is $5,000. The number of cars sold per week and their probabilities mimic the outcomes of three coins being flipped. The number of cars sold in a week was observed to be the same as the number of tails that appear when three coins are flipped. See the distribution:
What is the expected number of cars sold in one week?
a.1
b.1.5
c.2
d.2.5

The correct answer would be choice A: 1.

When 3 coins are flipped, there are 8 possible outcomes.

0 Tails = 1 ways
1 Tails = 3 ways
2 Tails = 3 ways
3 Tails = 1 ways

If you add up all the different tails, you could get 12 tails. Divide 12 by 8 and you have 1.5 which is the average number of tails you could expect to get by flipping 3 coins.

Solve the equation -10 (g - 6) = -65
Elanso [62]

Step-by-step explanation:

- 10(g - 6) =  - 65 \\  - 10g + 60  =  - 65 \\  - 10g =  - 125 \\   10g = 125 \\ g =  \frac{25}{2}

Explain why the following expression is false. |x| < -4
levacccp [35]

Step-by-step explanation:

Whenever we put a negative number inside a modulus function it will give us the positive output. For example , |-3| = 3 , |-6|=6, |5|= 5 ,etc.

So a modulus function i.e. |x| is always greater than zero ( positive ) when x is any number except 0 and it is equal to zero when the value of x is 0.

So |x| can't be less than -4 as |x| is always positive . So the statement is false.

Addie walked 2 1 2 miles in 45 minutes. Suzie covered 2 2 5 miles in 2 3 of an hour. Which girl walked faster? By how much?
kobusy [5.1K]

Answer:

Suzie walks faster by 0.27 miles per hour.

Step-by-step explanation:

Addie walked 2\frac{1}{2} miles in 45 minutes and Suzie covered 2\frac{2}{5} miles in \frac{2}{3} of an hour.

So, Addie walked 2.5 miles in 45 minutes i.e. \frac{45}{60} = 0.75 hours.

Therefore, the walking speed of Addie is \frac{2.5}{0.75} = 3.33 miles per hour.

Again, Suzie covered 2\frac{2}{5} i.e. 2.4 miles in \frac{2}{3} i.e. 0.67 hours.

So, the walking speed of Suzie is \frac{2.4}{0.67} = 3.6 miles per hour.

Hence, Suzie walks faster by (3.6 - 3.33) = 0.27 miles per hour. (Answer)

Paul and his neighbors decided to build a fence along his farm. After three hours, they have 15 meters of fencing complete. They
Goshia [24]

Let the  be the time in hours, and  meters of fencing completed. 

We know that After three hours, they have 15 meters of fencing complete, our graph will go from the point (0,0) to the point (3,15). We also know that they decide to take a 2-hour break for lunch and then resume building the fence, so our graph will go from the point (3,15) to the the point (5,15). Finally, After four more hours, they have a fence that is a total of 55 meters long, so the final part of our graph will go from the point (5,15) to the point (9,55)


We can conclude that the graph of t vs y is:
