Find the mean, median, mode, and range of this data: 49, 49, 54, 55, 52, 49, 55. If necessary, round to the nearest tenth.
Zigmanuir [339]
The mean is the average.
So, to find the mean you want o add up all of the numbers and then divide by the number of numbers.

49 + 49 + 54 + 55 + 52 + 49 + 575 = 363
363 / 7 = 51.85
Rounded to 52

For the median you want o line all of your number up from least to greatest and then find the middle number.

49,49,49,52,54,55,55

Your median is 52

The mode is the number that is listed most often

49 is listed 3 times
54 is listed 1 time
52 is listed 1 time
55 is listed 2 times

So, your mode is 49

Write an equation of the line that passes through (18,2) and is parallel to the line 3y-x=-12 .
uysha [10]

Answer:

y = \frac{1}{3}x-4

Step-by-step explanation:

<u>Step 1:  Solve for y in the first equation</u>

3y - x = -12

3y - x + x = -12 + x

\frac{3y}{3} = \frac{x}{3} - \frac{12}{3}

y = \frac{1}{3}x - 4

<u>Step 2:  Determine the important aspects</u>

We know that our line is parallel to the other line that has a slope of 1/3 which means that our slope is also going to be 1/3.  We also know that our line crosses the point (18, 2) which means that we can use the point slope form to determine our equation

Point Slope Form → (y-y_1) = m(x - x_1)

<u>Step 3:  Plug in the information and solve</u>

(y-2) = \frac{1}{3}(x - 18)

y - 2 = \frac{1}{3}x - 6

y - 2 + 2 = \frac{1}{3}x - 6 + 2

y = \frac{1}{3}x-4

Answer: y = \frac{1}{3}x-4

Which of the following statements is true?
sdas [7]

Answer:

Option The product of (-x+4)(x^2+3x-3) is

-x^3+x^2+15x-12 is correct.

That is (-x+4)(x^2+3x-3)=-x^3+x^2+15x-12

Step-by-step explanation:

Given expression is (-x+4)(x^2+3x-3)

To find the product of the given expression :

(-x+4)(x^2+3x-3)

( By using the distributive property each term in the factor is multiplied by each term in the another factor )

=[-x(x^2)+(-x)(3x)+(-x)(-3)]+[4(x^2)+4(3x)+4(-3)]

=-x^3-3x^2+3x+4x^2+12x-12 ( adding the like terms )

=-x^3+x^2+15x-12

Therefore (-x+4)(x^2+3x-3)=-x^3+x^2+15x-12

Therefore Option The product of

(-x+4)(x^2+3x-3) is -x^3+x^2+15x-12 is correct.

That is (-x+4)(x^2+3x-3)=-x^3+x^2+15x-12
