In a lottery game, a player picks six numbers from 1 to 22. If the player matches all six numbers, they win 20,000 dollars. Othe

Angelina_Jolie [31]

Answer:

Total possible number of outcomes = C(24,6) [24 choose 6]

=24!/(6!18!)

= 134596

Out of which there is only one winning combination.

Therefore we conclude:

P(win 20000)=1/134596

P(lose 1)=134595/134596

and hence the expected value is:

20000*(1/134596)+(-1)*(134595/134596)

=-114595/134596

=-0.8514 (rounded to four places after decimal)

Clay is filling 6.5 bottle of salsa, He was able to fill 7.5 bottles. How many ounce of salsa did he have? Draw an area model to

VMariaS [17]

Answer: He had 48.75 oz of salsa.

Step-by-step explanation:

I guess that Clay is filling 6.5 oz bottles of salsa.

And we know that he was able to fill 7.5 of these bottles, then if each bottle has 6.5 oz, 7.5 of them have a total mass of salsa will be equal to 7.5 times 6.5 ounces, this is:

M = 7.5*6.5 oz = 48.75 oz

This means that Clay had 48.75 ounces of Salsa

A drawn model to show this is seen below.

Each big square represents 0.5 oz, and the area black delimited area represents a total amount of 6.5 oz, we have 7 of them, then you can draw that 7 times, and count the squares, and then you will find the total ounces of salsa that Clay had, which is equivalent to the multiplication we did above.

PLEASE HELP ME IM MARKING ANSWER BRAINLIEST RIGHT NOW!!Mr. Youngbear buys T-shirts in boxes

Musya8 [376]

Step-by-step explanation:

1. Ok so first we need to figure out how many boxes of shirts he bought. In each box there are 20 shirts and he sold 93. So if we round it, he bought about 100 T-shirts. 100 ÷ 20 = 5. So he bought 5 boxes of shirts.

2. Next we need to figure out how much he spent on the shirts. 5*80=400. So he spent $400 dollars on the shirts.

3. We need to find out the amount of money he made from selling the shirts. 6*93=558

4. We need to find the profit so you subtract the total expenses from the total revenue. 558-400= 158. So the profit is $158

Answer: Mr. Youngbear made 158 dollars worth of profit after selling 93 T-shirts.

(I dont know if this is correct, but I hope I was able to help!)

and United States Lowe's sells particular carpet for $4.88 per square foot in the United Kingdom carpetright sells assembler car

Alisiya [41]

The carpet of United Kingdom carpet-right is cheaper by 3.33 dollars/ft²

Explanation

Price of the carpet in United States Lowe's is 4.88 dollars/ft²

Price of the carpet in United Kingdom carpet-right is 12.99 pound sterling/m²

1 pound sterling = 1.28 US dollars and 1 meter = 3.28 ft . So....

12.99 pound sterling/ m²

$=\frac{(12.99) pound sterling}{(1 meter)^2}\\ \\ = \frac{(12.99*1.28)dollars}{(3.28 ft)^2} =\frac{16.6272 dollar}{10.7584 ft^2}= 1.55 dollar/ft^2$

As the unit price of the carpet per square feet in United Kingdom carpet-right is less than United States Lowe's, so the carpet of United Kingdom carpet-right is cheaper by $(4.88-1.55)dollar/ft^2 = 3.33 dollar/ft^2$
