Find the mean median and mode of the refrigerator prices shown in the table. Witch measurement might be misleading to describing
ioda

Answer:

We need the picture.

Step-by-step explanation:

Unless the data is skewed (which means there is outliers) then you use mean as the most accurate. If you have a skewed graph or outliers then mean would mislead you to believe prices are higher (if you have high outliers) or low (if you have low outliers). Median is typically very accurate. Mode may be inaccurate if you have a lot of prices in a really high or low value.

In the table below, x represents the miles traveled and y represents the cost to travel by train.
Afina-wow [57]

Answer:

Third option

m = 2.25

Step-by-step explanation:

The slope of the function is equal to its rate of change between two points.

For example, for a couple of points (x_1, y_1),\ (x_2, y_2)

The slope is:

m =\frac{y_2-y_1}{x_2-x_1}

In this problem we have the following points

1.(2, 8.50) , 2. (5, 15.25), 3. (8, 22.00) , 4. (12, 31.00)

We calculate the slope between the first two points

m =\frac{15.25-8.50}{5-2}=2.25

We calculate the slope between the points 3 and 4

m =\frac{31-22}{8-4}=2.25

We calculate the slope between the points 2 and 3

m =\frac{22-15.25}{8-5}=2.25

The slope is always the same. Therefore m is constant and the fution is a line of slope m = 2.25

Which equation represents the graph?
klio [65]
The second option.

That is because
y -3 = - \frac{1}{2}(x + 1) \\ (y -3)+3 = (- \frac{1}{2} x - \frac{1}{2}) + 3 \\ y = - \frac{1}{2}x + 2 \frac{1}{2}
