For questions #6-8, use this data set and show your work  5, 10, 12, 4, 6, 11, 13, 5
Pachacha [2.7K]
Mean (average) can be found by adding up all the numbers and then dividing that by how many numbers there are.
(5+10+12+4+6+11+13+5) / 8 = 66/8 = 8.25 <==

the mode (the number used most often) = 5....just so u know, there doesn't have to be a mode, and sometimes there is more then 1 mode. But for this one, the mode is 5. <==

median (the middle number)...for this, u put the numbers in order...
4,5,5,(6,10),11,12,13
now start moving from both ends going inward until u find the middle number...keep in mind, when u have an odd number of numbers, u will have 1 middle number.....but when there is an even number of numbers, like in this case, u will have 2 middle numbers...so u take ur 2 middle numbers, add them, then divide by 2 to get ur median.
median = (6 + 10) / 2 = 16/2 = 8 <==

How would I solve this?<br><br>(3x-4) - (4x-1)​
saveliy_v [14]

Answer:

-x - 3

Step-by-step explanation:

(3x - 4) - (4x - 1)​ =

The first set of parentheses is unnecessary, so you can just remove it.

= 3x - 4 - (4x - 1)​

To remove the second set of parentheses, you must distribute the negative sign to its left by the terms inside the parentheses. To do this, change every sign inside the parentheses.

= 3x - 4 - 4x + 1

Now combine like terms. Terms with x are like terms and are combined together. Therms without x are like terms and are combined together.

= 3x - 4x - 4 + 1

= -x - 3

I dont know the answer to this question I dont know what I can put for the x and the y
harina [27]

Answer:

  (x, y) = (-4, 4)

Step-by-step explanation:

You find the values of x and y by working the problem using any of the methods of solving simultaneous equations that you have been taught.

Here, you observe that the y-coefficients are the same in each equation. That means you can cancel the y-terms by subtracting one equation from the other.

  (7x +6y) -(4x +6y) = (-4) -(8)

  3x = -12 . . . . simplify

  x = -4 . . . . . . divide by 3

Now, you can substitute this into either equation to find y.

 4(-4) +6y = 8

  6y = 24 . . . . . . . . add 16

  y = 4 . . . . . . . . divide by 6

The solution to this system of equation is ...

  • x = -4
  • y = 4
