Answer:

the answer is actually B

Step-by-step explanation:

when drawn as a box and scatter plot, both appear to be closely symmetrical. as we know, standard deviation is used for symmetrical data, and the IQR is used for data that is not symmetrical.

i am unable to attach the box plots, but try drawing it out!

Answer: Good thing you provided the image!

Working down the columns:

C base= 2

D base = 4

C height =3

D height = 2

C area = bh = 8

D area = bh = 8

Step-by-step explanation:

Try thinking about drawing a rectangle around the entire image of C and D, connecting each of the corners (sort of like what is being done for B) and then you can perceive the b and h.

The trick to D is to turn your head 90 degrees (or sideways) so you can see those 4 boxes as the base.

For C the base is the 2 boxes, and going up until you meet the other parallel side you can count 4 boxes.

I usually default to using the side which I can easily count boxes as the base and go from there.

If it is not a natural number, then it is not a whole number. True or false?
-BARSIC- [3]

Answer:The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.

Step-by-step explanation:

Swati is substituting t=5 and t=9 to determine if the two expressions are equivalent.
horrorfan [7]

Answer:

No the two expressions are not equivalent.

Step-by-step explanation:

the given two expressions t=5 and t=9 are not equivalent because t being a variable cant take two numbers at a same time.however if they are placed in given two expressions of 't' such that that they give equal value when the first expression gives a value 'a' at t=5 while the other expression gives a value 'a' at t=9 then those two expressions will be equal.
