Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

Answer:

888

Step-by-step explanation:

Add the 55 and 833

833+55=888

Answer:

118.50

Step-by-step explanation:

1000-348.25= 651.75

651.75 ÷ 5.5 = 118.5

Answer:

W = 100

Step-by-step explanation:

2/5 of w is 40

1/5 of w is 40/2, which is 20

Since we know that 1/5w is 20, then we can find w by multiplying both sides by 5 so then we can get rid of 1/5.

20*5 = 100

W = 100

OR

0.4w=40

Divide by 0.4 on both sides

w = 100

Answer:

No; There is no constant of proportionality.

Step-by-step explanation:

29.98 divided by 50 is 0.5996 and 15.49 divided by 25 is 0.6196. They are not proportional nor are they equal. There is a difference of 0.02.

Answer: divide the area buy the sides

Answer:

415.27in^2

Step-by-step explanation:

area of a circle is

a= pi(r)^2

the radius is half of the diameter so you would do 23/2 = 11.5 for the radius

a= 3.14 (11.5)^2

= 3.14 x 132.25

= 415.27 inches^2

Answer:

\(4^{2} = 4 x 4 =16\)

Step-by-step explanation:

First of all we need to understand what a perfect square is:

It is an integer which is the square of another integer integer; in other words, it is the product of some integer with itself.

For example: 9, this is a square number since itt equals \(3^{2}\) and 3x3 = 9

Answer:

1. 10218

2. 9720

Step-by-step explanation:

1 ---------------

need to find the least 5 -digit number leaving same remainder when divided by 12, 18, 21, 28

Least 5-digit number is 10000, when it is divided by 262, we get

10000/262= 38.17

39*262= 10218, this number leaves 0 remainder when divided by all 4 given numbers, any number leaving more remainder will be greater than this

Answer: 10218

2 -----------------

Greatest 4-digit number exactly divisible by 12, 18, 40, 45

Greatest 4 digit number is 9999

9999/360= 27.78

360*27= 9720 is the greatest number we are looking for

Answer: 9720

Answer:

40%

Step-by-step explanation:

2/5= 4/10

4/10= 40%

The percent that is equivalent to two-fifths is 40%. The correct option is 40%.

To determine the percent equivalent to two-fifths, we need to convert the fraction into a percentage.

The fraction two-fifths can be written as 2/5. To convert this fraction to a percentage, we divide the numerator (2) by the denominator (5) and multiply the result by 100.

2/5 x 100

= 0.4 x 100

= 40%

Therefore, the percentage equivalent to two-fifths is 40%.

Among the provided options:

0.4% is incorrect. It represents four-tenths of a percent, not 40%.

2.5% is incorrect. It represents two and a half percent, not 40%.

25% is incorrect. It represents one-fourth or 25%, not 40%.

40% is the correct answer, as explained above.

Hence, the option that represents the percent equivalent to two-fifths is 40%.

Answer:

Yea the guys is right. B

Step-by-step explanation:

What makes a NUMBER rational is the ability to have a perfect square root, cube root, or have these components: Perfect square/cube, whole number, repeating (pattern) decimal, termination decimal, and I think one more that I can't remember.

The properties of the rational exponents are given and a rational equation is of the form b = aˣ

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the rational exponent equation be A

Now , the properties of the exponent equations are

mᵃ×mᵇ = mᵃ⁺ᵇ

The powers of the exponents are added together

mᵃ / mᵇ = mᵃ⁻ᵇ

The powers of the exponents are subtracted together

( mᵃ )ᵇ = mᵃᵇ

The powers of the exponents are multiplied together

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

Any number raised to the power of 0 is 1

m⁻ᵃ = ( 1 / mᵃ )

Hence , the exponents are solved

Answer:  -7

Step-by-step explanation: To find the mean, here is the equation =

Divide the sum of all values in a data set ÷ the number of values = mean (average)

Step 1 :

So we do =

17 + -25 + 3 + -29 + -15 + 7 = -42

So the sum of the integers is -42

Step 2 :

We divide the sum by the number of values.

17, -25, 3, -29, -15, 7

1      2   3     4      5   6

So there are 6 values.

We do =

-42 ÷ 6 = -7

So the mean (average) of these integers is -7
