Choose all the numbers that are part of the counting/natural number system
a) 0
b) 2
c) 1/2
d) -3 7

2

Step-by-step explanation:

Counting/Natural Number System  is counting nymbers so counting on your fingers you strat with 1, then 2,3,4,5,6,7,8, etc. you dont say 1/2 or -3 7 but 0 is sometimes considered a whole number but we never start with 0 so the only number choices i see that is in the Counting/Natural Number System  is 2 hope this helps!

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate
