3x³ - 15x² + 13x² - 65x + 4x - 20

[3x²(x - 5) + 13x(x - 5) + 4(x - 5)]/(x-5)

Suppose when a baseball player gets a hit, a single is twice as likely as a double which is twice as likely as a triple which is
rjkz [21]

Answer:

The PMF of B is given by

P(B=0) = 0.7

P(B=1) = 0.16

P(B=2) = 0.08

P(B=3) = 0.04

P(B=4) = 0.02

Step-by-step explanation:

Let x denote P(B=1), we know that

P(B=0) = 1-0.3 = 0.7

P(B=1) = x

P(B=2) = x/2

P(B=3) = x/4

P(B=4) = x/8

Also, the probabilities should sum 1, thus

0.7+x+x/2+x/4+x/8 = 1

15x/8 = 0.3

x = 0.16

As a result, the PMF of B is given by

P(B=0) = 0.7

P(B=1) = 0.16

P(B=2) = 0.08

P(B=3) = 0.04

P(B=4) = 0.02

tensa zangetsu [6.8K]

If he bought 4 hats for $5 each and he spent a total of $44, he spent $44 - $20 in shirts.

44 - 20 = 24

2 shirts for $24 is 1 for 12

$12 for each shirt

Hope it helps :)

A wallet is marked with a sale sticker saying it is 76% off. The original price is $57.41. What is the sale price?
liubo4ka [24]
Answer: The sales price is $13.78


The original price is $57.41. It is selling at 76% off.
First, we need to find the discount. To find the discount, we need to find out what is 76% of $57.41

-------------------------------------------------
Find discount
-------------------------------------------------
76% x $57.41               ← change the percentage to decimal

= 0.76 x 57.41

= $43. 63 (nearest hundredth)

Now that we know the discount, we can find the sales price by subtracting the discount from the original price.

-------------------------------------------------
Find sales price
-------------------------------------------------
$57.41 - $43.63 = $13.78

-------------------------------------------------
The sales price is $13.78.
