First we need to find the probability of selecting the 1 blue marble out of the 20 marbles total, which is 1/20.

Next, we need to find the probability of tossing the fair coin so it lands tails up, which is 1/2.

To find the probability of both events happening, we need to multiply the probabilities of the two individual events:
1/20 * 1/2 = 1/40

So the answer is 1/40, or 2.5%

Sorry about the poor formatting :( I'm on my phone at the moment, which makes it difficult.

Hope I helped, and let me know if you have any questions :D

Likurg_2 [28]

Answer:

x = -8/29 = -0.276

Step-by-step explanation:

Step  1  :

Solving a Single Variable Equation :

1.1      Solve  :    29x+8 = 0

Subtract  8  from both sides of the equation :

                     29x = -8

Divide both sides of the equation by 29:

                    x = -8/29 = -0.276

One solution was found :

                  x = -8/29 = -0.276

Show work and explain. Which is better: 15 ounces for $1.79 or 12 ounces for $1.49?
Leokris [45]
Find the prices per ounce by dividing the dollars by the number of ounces:-

1.79 / 15 = 0.1193 dollars  per ounce

1.49 / 12 =  0.1242 dollars per ounce


So the first  one is the better buy.

Tom rode his horse for 4/6 miles. Liz rode her horse for an equal distance. What is an equivalent fraction that describes how fa
Natasha_Volkova [10]
If you where to simplify 4/6 you will get an equivalent fraction. So you would find a common numeral between the tw0. In this case it would be 2. So it would be 2/3 cause you would divide each number by two to get 2/3.

Hello!

To find the circumference, you multiply the diameter by pi. We will do so below.

2.5\pi≈7.85

a. 7.85 feet

___________________________________________________

To find how many rotations it will take to travel a mile, we will need to divide our mile by our circumference.

5,280/7.85≈672.61

b) 672.61

I hope this helps!
