You should use a median as a measure of center when you have data that is not distributed evenly. For example, if you have a number that is a lot bigger or smaller than most of the numbers, using the mean would be a better way to show one value to represent the information. When representing data on a line/dot plot or a histogram, you should use the median to represent the data if it is skewed left or right. This means it looks longer on one side or when looking at the middle, it does not look the same on both sides (symetric).

This holiday weekend, Dave is going to Chicago to shop and see a baseball game. To avoid traffic, Dave decides to take the train

kondaur [170]

Answer:

k= 1 mile per minute

Step-by-step explanation:

There is a proportional relationship between the time (in minutes) Dave spends riding the train, x, and the distance he travels (in miles), y.

The table representing this information is given below:

$\left|\begin{array}{c|ccccc}$x (minutes) & 8 &10&13&14 \\$y (miles) & 8 &10&13&14 \end{array}\right|$

The equation of proportionality is given as: y=kx

When x=8, y=8

Substituting we have:

8=8k

Divide both sides by 8

k=1

Therefore, the constant of proportionality, k= 1 mile per minute

If two expressions, 2x + 8 and 2 (x + 2) + k are equivalent, what is the value of k? Enter the value in the box.

Nitella [24]

2x+8=2(x+2)+k
2x+8=2x+4+k
k=4

Therefore k= 4, Hope this helps!! :)
