Probability of winning = 0.6 , Probability losing = 1-0.6 = 0.4

Expected value = 50(0.6) - 1(0.4)  =  $29.6

The interpreation of this is that if you play many times you would expect a profit of $29.6.

notka56 [123]

Answer:

answer is $5.12

Step-by-step explanation:

Using the formula two and replacing the given values:

Sale Price = Original Price - Amount Saved. So,

Sale Price = 6.40 - 1.28

Sale Price = $5.12 (answer)

This means, the cost of the item to you is $5.12.

You will pay $5.12 for an item with original price of $6.40 when discounted 20%. In other words, if you buy an item at $6.40 with 20% discounts, you pay $6.40 - 1.28 = $5.12

Suppose Have you received a amazon promo code of 1.28. If the price is $6.40 what was the amount saved in percent:

3) 1.28 is what percent off $6.40?

Using the formula two and replacing the given values:

Amount Saved = Original Price x Discount % /100. So,

1.28 = 6.40 x Discount % / 100

1.28 / 6.40 = Discount % /100

100 x 1.28 / 6.40 = Discount %

128 / 6.40 = Discount %, or

Discount % = 20 (answer)

3y-12x=24 and goes through point (2,-6) . write your answer in y=mx+b
Masteriza [31]

Answer:

y= 4x+8

Step-by-step explanation:

Add 12x to both sides.

3y=24+12x

The equation is in standard form.

3y=12x+24

Divide both sides by 3.

3

3y

​

=

3

12x+24

​

Dividing by 3 undoes the multiplication by 3.

y=

3

12x+24

​

Divide 24+12x by 3.

y=4x+8
