Thirteen babies were born in a hospital on the same day. the weights of the babies (in pounds) were 5.5, 6.4, 5.8, 8.1, 9, 7.6, 8.2, 7.2, 8.8, 6.6, 5.4, 7.7, and 6.9. which measure will you calculate how much the babies' weights vary, on average, from their mean weight? a. mode b. interquartile range c. range d. mean absolute deviation e. quartile

To answer this, we will look at simple definitions of each term. From the definitions, it will be clear which one is correct.

What is mode?

It is the most occurring number.

What is interquartile range?

It is the difference between third quartile and first quartile.

What is range?

It is largest number minus the smallest number.

What is mean absolute deviation (MAD)?

It is the average distance of each data point from the mean.

What is a quartile?

It is one of the four groups in which a dataset is divided.

From the simple definitions of each term, we can clearly see that Mean Absolute Deviation (MAD), answer choice D, is the correct answer.

Mean Absolute Deviation

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
