Step-by-step explanation:

To find the mean, you add all the numbers together then divide by the number of numbers.

Charge : 120+272+358+328+406+392+530+592+610=3608/9=400.888888 =400.89 dollars

<h3>Answer: 400.89</h3>

=======================================================

Work Shown:

To find the average price, we will add up the 9 values in column 2 to get

120+272+358+328+406+392+530+592+610 = 3,608

Then divide that total by 9 since there are 9 values we added up

We get the average to be (3,608)/9 = 400.888 which is approximate. This rounds to 400.89

Side note: It's a bit strange how your teacher mentions "charge in pounds" but then uses a dollar sign.

Answer:

$\frac{53}{6}$

Step-by-step explanation:

$\int\limits^4_3 {x^2-x} \, dx$

= [ $\frac{x^3}{3}$ - $\frac{x^2}{2}$ ] ← evaluate for upper limit - lower limit

= ( $\frac{64}{3}$ - $\frac{16}{2}$ ) - ( $\frac{27}{3}$ - $\frac{9}{2}$ )

= $\frac{64}{3}$ - 8 - 9 + $\frac{9}{2}$

= $\frac{155}{6}$ - 17

= $\frac{53}{6}$

What does the ! Mean

Alina [70]

Answer:

! means factorial . For example 3! (factorial 3) = 3*2*1 = 6

Answer to 14C3 is 364

Step-by-step explanation:

14! = 14*13*12*11*10*9*8*7*6*5*4*3*2*1

14C3 = 14*13*12*11*10*9*8*7*6*5*4*3*2*1 / 3*2*1 * 11*10*9*8*7*6*5*4*3*2*1

= (14*13*12) / 3*2*1

= 14*13*2

= 364

Solve for x.<br> 8(5 + x) = 11(9 + x)<br> Answer as a fraction.

7nadin3 [17]

distribute the 8 to the 5 and x. then distribute 11 to 9 and x.

(40+8x)=(99+11x)

-11x -11x

-3x+40=99

-40 -40

-3x= 59

divide three on both sides

x=59/-3

final answer x=-59/3

Marcus has three random samples of the same size from a population of 700 people. In one sample, 53% of people have a library ca

Lapatulllka [165]

Answer:

343

Step-by-step explanation:

Finding? How many people with a library card should he expect in the population?

Important? Population = 700. Sample 1= 53%. Sample 2 = 51%. Sample 3 = 43%.

How? Average the 3 samples percentages together. The percent sign tells us what the sample size is (% = out of 100). Set up the proportions for library card to sample size and then library card to population. Cross multiply.
