Find The Area Of Each Circle With The Given Radius Or Diameter. Use 3.14 For Pi.

Answers

Answer 1

Answer:

Read explanation

Step-by-step explanation:

r=4in  4^2 is 16 then multiply it by 3.14 to get 50.24

r=2in  2^2 is 4 then multiply it by 3.14 to get 12.56

d=2in Since you have the diameter first, you just divide it by 2 and your radius is 1. 1^2 is 1     1*3.14=3.14

r=8in 8^2 is 64 then multiply it by 3.14 to get 200.96

d=12in divided 12 by 2 and you get 6. 6^2 is 36, multiply that by 3.14 to get 113.04

Will both the mean and median increase? Just one? Will they decrease?

Thank you! x

Answers

Answer:

Decrease Median and Mean

Step-by-step explanation:

The mean and median will both be decreased because you are removing the largest number value from the number line, logically it must decrease.

Answer:

Before Suzanne left:

Mean = 53,333

Median = 45,000

After Suzanne left:

Mean = $44,000

Median =  $44,000

Step-by-step explanation:

Since the larger number was taken away the mean and median decreased after she left. The 100,000 is an outlier which basically holds up the mean and median salary.

Step-by-step explanation:

If both sides are symmetrical, then there is no need to try and find the mean or anything because you already have the middle point and no outliers. If there were outliers it'd be different, unless the outliers were symmetrical with the rest of it, then the median would still be a good option.

A computer is used to generate passwords made up of numbers 0 through 9 and uppercase letters. The computer generates 500 passwords one character at a time.

A uniform probability model is used to predict the first character in the password.

What is the prediction for the number of passwords in which the first character is a number?

Round your answer to the nearest whole number.


69 passwords

139 passwords

192 passwords

292 passwords

Answers

Answer:

139

Step-by-step explanation:

Just took the quiz on K-12

Hope its not to late

The prediction for the number of passwords in which the first character is a number is 139. Therefore, option B is the correct answer.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

The answer is 192 passwords. This is because there is an equal probability of each character (0-9 and uppercase letters) being chosen as the first character of a password.

Since there are 10 different numbers (0-9) and 26 uppercase letters, the probability of the first character being a number is 10/36

If 500 passwords are generated, the expected number of passwords in which the first character is a number is 500 ×10/36

= 5000/36

= 138.88

≈ 139

Therefore, option B is the correct answer.

The conversion of a temperature from Celsius to Fahrenheit is represented by the expression below, where C is the temperature in degrees Celsius.

9/5 x C + 32


Use the expression to find the Fahrenheit temperature equivalent to 20° C.

A.
36° F
B.
68° F
C.
48° F
D.
52° F

Answers

Answer:

B.

Step-by-step explanation:

C= 20 degrees Celsius

20 x 9/5 = 180/5

180 divided by 5 = 36 degrees celsius

Then you do 36 degrees celsius + 32 and you get 68.

So therefore 20 degrees celsius is eqivalent to 68 degrees Fahrenheit.
