Answer:

(B)

Step-by-step explanation:

The given data set is:

228, 251, 22, 206, 254, 288, 228, 242

Since, in the given data set, 22 is an outlier which will affect the mean of the data, thus mean cannot be used to measure the center of the data due to the presence of an outlier.

Also, the median is the central value which is used to measure the center of the given data set, thus median can be used to find the measures of center.

The mode can be calculated for qualitative data as well as for quantitative data and can also be used to find the measures of center.

Thus, option B is correct.

Answer:

y = 10/11 x + 2.45

Step-by-step explanation:

Equation of the line

First find the gradient

formula = $\frac{y2-y1}{x2-x1}$

= $\frac{-3-7}{-6-5}$

= $\frac{-10}{-11}$

= 10/11

m is the gradient

equation of a line

y- y1 = m(x-x1)

y-7 = 10/11 (x-5)

y-7 = $\frac{10}{11}x$ - $\frac{50}{11}$

y = 10/11 x + 2.45

NB i rounded of -50/11 +7 = 2.4545..... to 2.45

What are both of the ranges

MArishka [77]

Answer:

0.8 < x < 16.8

Step-by-step explanation:

The third side of the triangle is always less than the other two sides combined. I think of it like if it was greater than the other two sides added, there would be no triangle- it'd be a line.

The other rule is that it has to be greater than the difference between the two lines.

I hope this helped!
