DEFINITION: In statistics, an outlier is an observation that is
numerically distant from the rest of the data.
How to calculate an outlier
1) Subtract the lower quartile from the higher quartile
to get the interquartile range, IQ.
2) Multiply the interquartile range by 1.5. Add this to
the upper quartile and subtract it from the lower
quartile. Any data point outside these values is an
outlier.
The lower fence is the lower cut-off point for outliers
The upper fence is the upper cut-off point for outliers
Lower Fence = Q1 - 1.5(IQ)
Upper Fence = Q3 + 1.5(IQ)

a is the right answer

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
