Answer:

26/51

Step-by-step explanation:

Probability Formula = No of possible events ÷ Number of events

We are given a standard deck of 52 cards. Hence,

The number of events = 52

It is important to note that in a standard deck of 52 playing cards,

26 are red

26 are black

WITHOUT REPLACEMENT

Probably of drawing

a red card = 26/52 = 1/2

We are asked to find the probability of drawing a second card that is black

Probability of drawing a black card = No of possible outcomes / Number of events

Number of possible outcomes = 26 Due to the fact that the red card after been drawn was not replaced,

Number of events = 51

Hence , Probability of drawing a black card = 26/51

Therefore, the Probability of drawing a black card =

P (black ) = 26 /51

The big dog weighs 5 times as much as the little dog. The little dog weighs 2 3 as much as the medium-sized dog. The medium-size
disa [49]

Answer:

The answer to your question is the big dog weighs 120 pounds

Step-by-step explanation:

Data

big dog = b    

medium dog = m

small dog = s

Equations

       b = 5s

       m = 12 + s

       s = 2/3 m

Process

1.- Substitute m in the last equation

       s = 2/3(12 + s)

       s = 24/3 + 2/3s

       s - 2/3s = 8

       1/3 s = 8

             s = 8(3)

             s = 24 pounds

2.- Substitute s in the first equation

        b = 5(24)

        b = 120 pounds

A sphere has a radius of 11 feet. A second sphere has a radius of 8 feet. what is the difference of the volume of thespheres
Veronika [31]

The difference between the volume of the spheres is 3428.88 cubic feet

Explanation:

Given that one sphere has a radius of 11 feet.

A second sphere has a radius of 8 feet.

<u>Volume of the 1st sphere:</u>

The formula to determine the volume of the sphere is given by

V=\frac{4}{3} \pi r^3

Volume of the 1st sphere is given by

V=\frac{4}{3}(3.14)(11)^3

V=\frac{4}{3}(3.14)(1331)

V=\frac{16717.36}{3}

V=5572.45

The volume of the 1st sphere is 5572.45 cubic feet.

<u>Volume of the 2nd sphere:</u>

Volume of the 2nd sphere is given by

V=\frac{4}{3}(3.14)(8)^3

V=\frac{4}{3}(3.14)(512)

V=\frac{6430.72}{3}

V=2143.57

The volume of the 2nd sphere is 2143.57 cubic feet.

<u>Difference between the volume of the two spheres:</u>

Difference = Volume of the 1st sphere - Volume of the 2nd sphere

                  = 5572.45 - 2143.57

Difference = 3428.88 cubic feet.

Hence, the difference between the volume of the spheres is 3428.88 cubic feet.
