A weather forecast states that there is a 20% probability of rain on each of the next 3 days.


Complete the description of a simulation you could perform using random numbers to find the experimental probability that it will not rain on any of the next 3 days.



To simulate a 20% probability of rain over 3 days, let
of 10 numbers represent a day with rain. So,
of the numbers represent a day without rain. Then, perform multiple trials, generating
random numbers for each trial.

Answers



answer: The experimental probability that it will not rain on any pf the next 3 day is 64/125


The probability of raining is 20%
Hence, the probability that there will be no rain, is (100-20) = 80%
The probabilty that there is no rain on the first day is 80/100 = 4/5


Hence, the required probaility is (4/5)3 = 64/125

Finding the Surface Area :

Area (2 triangles) + Base rectangle + Left rectangle + Right rectangle2 x 1/2 x 4 x 5 + 9 x 5 + 6 x 9 + 5 x 920 + 45 + 54 + 4565 + 99164 cm²

Step-by-step explanation:

just take a deep breath, shake your limbs, and then focus on it again.

the surface consists of 5 areas :

front and back triangles (2)

left rectangle

right rectangle

floor rectangle

the area of a rectangle is simple :

length × width

the area of a triangle is

baseline × height / 2

each of the front and back triangles has an area of

5 × 4 / 2 = 5×2 = 10 cm²

both of them have then 10×2 = 20 cm²

the left rectangle is

9×6 = 54 cm²

the right rectangle is

9×5 = 45 cm²

the floor rectangle is also

9×5 = 45 cm²

so, the total surface area is

20 + 54 + 45 + 45 = 164 cm²

Describe how you would use unit cubes to determine the volume of the rectangular prism below. What is the volume of the rectangular prism? A cube that is five inches in length width and height.

Answers

Answer:

Unit Cubes = 125 in

Volume = 125 in

Step-by-step explanation:

To find the volume of a rectangular prism, we multiply the length of the prism by the width of the prism by the height of the prism.

Volume of rectangular prism = length x width x height

Advance explanation:

The formula to find the volume of the rectangular prism is this:

L x W x H = V

L = Length = 5 in

W = Width = 5 in

H = Height = 5 in

V = Volume = 125

You first need to multiply the Length with the Width then multiply the Length and Width with the height (5 x 5 x 5), after that your answer will be 125 In

Hope this helps!

Summarized Steps:

Multiply the Length and Width with the Height (L x W x H).Your answer will be the result of the equation.

Answers

The number of the blue leashes will be 240.

What are linear equations?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

It is given that:-

A pet shop owner bought 320 leashes. 30% of these leashes were pink leashes and the rest were blue and green leashes.The number of blue leashes is 3 times the number of green leashes.

The number of the blue leashes will be calculated as:-

L     =    320

B   +    P   +   g   =   320

{ (320  x   0.3 ) } + 0.7 ( B  +  g ) =  320

( 96 )  +   ( 2.8g )   =   320

2.8g   =   320 / 96

g   =   222  /  2.8  =  80

Now  B  =   3  x  g

B   =   3   x   80

B   =   240

Therefore the number of the blue leashes will be 240.

The Smiths have a​ rectangular, above-ground swimming pool. The manufacturer says that the pool holds​ 14,040 gallons of water when filled to capacity. After it is​ filled, Mr. Smith follows the​ manufacturer's recommendation of adding 1 ounce of chlorine for every​ 2,700 gallons of​ water, every other day. About how many pounds of chlorine will Mr. Smith add to the pool in 3​ weeks?

Answers

Answer:

54.6 ounces

Step-by-step explanation:

14,040/2,700=5.2

3 weeks is 21 days

21 days divided by 2 because every other day is 10.5 days

5.2 times 10.5 is 54.6

54.6 ounces because 14,040 divided by 2,700 you will get 3 week and the 21 days so you would do is 21 days divided by 2 because every other day is 10.5 days. So, than 5.2 *10.5 is 54.6.
