A box of jerseys for a pick-up game of basketball contains 10 extra-large jerseys, 6 large jerseys, and 4 medium Jerseys. If you are first to the box and grab 2 jerseys, what is the probability that you randomly grab 2 medium jerseys? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.​

Answers

Answer: 3/95

Total Number of jerseys:

10+6+4=20

Odds of first jersey being medium:

4/20

Odds of second jersey being medium

3/19

(4/20)*(3/19)=12/380=

6/190=3/95

The probability that you randomly grab 2 medium jerseys is 3.15%.

Since a box of jerseys for a pick-up game of basketball contains 10 extra-large jerseys, 6 large jerseys, and 4 medium Jerseys, to determine, if you are first to the box and grab 2 jerseys, what is the probability that you randomly grab 2 medium jerseys, the following calculation must be performed:

10 + 6 + 4 = 20 4/20 x 3/19 = X 0.0315 = X 0.0315 x 100 = 3.15%

Therefore, the probability that you randomly grab 2 medium jerseys is 3.15%.

3) A grocery store has cereal on sale. If the original price is $4.50 and the sale
price is $3, what percent is the discount?

Answers

discount % = 33.33%--------------------------------

Step-by-step explanation:

original price = $4.50

sale price = $3

discount price = $4.50 - $3

= $1.50

discount = discount percent × original price ÷ 100

$1.50 = discount percent × $4.50 ÷ 100

discount percent = $1.50 × 100 ÷ $4.50

= 33.33%

Answers

Answer:

Step-by-step explanation:

Remark

x is opposite the 90 degree angle. It is the hypotenuse. 15 is opposite the 66 degree angle. It is the side opposite.The side opposite and the hypotenuse define the sin(theta).

Formula

sin(theta) = side opposite / hypotenuse

Givens

Theta = 66 degrees

Hypotenuse = x

Side Opposite = 15

Solution

Sin(theta) = 15 / x         Multiply both sides by xx*sin(theta) = 15           Divide by Sin(theta)x = 15/sin(theta)x = 15 / sin(66)sin(66) = 0.9135x = 15/ 0.9135x = 16.42

The point (0, 0) does not lie on the step function given by y = 4x + 2

What is a step function?

A step function can be represented by a linear function.

Let y represent the cost of charging the electric car for x hours, hence:

Station A is $2 to start and $4 for each hour or fraction of an hour:

y = 4x + 2

The point (0, 0) does not lie on the step function given by y = 4x + 2

Answers

Answer:

the answer is $65

Step-by-step explanation:

Answer:

$70

Step-by-step explanation:

Explanation

If we reverse it we can break it down easier: We start at $935

15 dollars on every purchase, he sold 11 TVs. So we find the total amount of money, 15*11=165

935-165=770

770 is the amount left without the money he has earned so the total base.

770/11=70

Checking answer

Let's rebuild it to test if it is correct...

$70 for each tv * 11 tv's = $770 or the base price of the tv's

$15 for all the warranties

$15*11=165

165+770=935

So the answer is 70$
