Answer:
2
Step-by-step explanation:
m= (y-y1)/(x-x1)
Points are (3, -2) and (6, 4)
m= (-2-4)/(3-6)= -6/-3= 2
m=2 to replace ? mark
So the distance formula: d = rad (x2 - x1)^2 + (y2 - y1)^2
it doesn't matter what order you do, you just have to make sure it's a y coordinate for y and an x coordinate for x.
rad (9-5)^2 + ((-6)-1)^2
rad 4^2 + (-7)^2
rad 16 + 49
rad 65
A. It is an experiment as the sales director is applying treatment ( the training ) to a group and recording the results.
B. I would have 250 sales representatives from each region take the training and 250 from each region to not take it so i can be able to see if it affects both regions differently. The representatives from each region would be chosen at random and the length of their training would be the same for all.
C. now you would only be able to have 200 people from each region train. this would lower the percentage of the impact the training had on the amount of sales ( if any) . For example, if the original 250 trained people in a region increased the sales in that region by 20 percent and 50 of those people ended up not actually training, the sales would have only increased by 16 percent.
D. correlational research is best to establish causality. for example, the amount of training the representatives got may affect how much they are able to sell. also the number of representatives trained may affect the amount sold
Answer:
Yup if you have 8+8=14 then 8+8-1=-1
First of all,we have to cancel off the denominator.
times 2 to the equation in order to cancel off the denominator "2"
(x2) x+2x-6/5=6
#all numbers in this equation will be timed by 2 as well
then times 5 to cancel off the denominator"5"
(x5) 5x+10x-6=30
#all of them are timed by 5
then u will see this equation:
5x+10x-6=30
plus up the unknown numbers,
15x-6=30
Move the negative number "-6" to the back of 30.
When negative number moved to the other side,it will become positive number.
Same as when positive number moved to the other side,it will become negative number.
Thus,
"-6” moved
become positive "6"
Usually positive means plus"+" while negative means minus"-".
15x=30+6
15x=36
Move 15 to the opposite side,
Timed by 15 become divided by 15.
Just like the positive and negative numbers,they forced to become the opposite things.
positive→negative OR negative→positive
plus→minus OR minus→plus
times→divide OR divide→times
Thus,
x=36÷15
OR u can write as fraction,
x=36/15
x=12/5
final ans:
x=12/5 OR 2.4
