Answer: 120
Step-by-step explanation:
The median of a given set for numbers will be gotten when we arrange the numbers that are given in either ascending or descending order and then get the number in the middle.
Therefore, since we are given 90,100,120,120,140, it means that we have 5 numbers and the 3rd number will be the median distance. Thus will be: = 120
The cube root is 10 bc 10x10x10 = 100
Answer: b. 3
Step-by-step explanation:
We know that , the indicator variable is a dummy variable in regression analysis which is used to denote either presence ( by 1 ) or absence ( by 0 ) of a nominal variable that can be responsible for the change in output.
Number of indicator variables = (all levels in the original variable)-1
Here , the given categories as per the location are northeast, northwest, southeast, or southwest.
i.e. all levels in the original variable = 4
Then, the umber of indicator variables we need = 4-1 =3
Hence, we need 3 indicator variables.
Thus , the correct answer is b. 3.
Answer:
72:48
Step-by-step explanation:
as you divide 120 by 5 as 3+2=5 and that equals 24
24x3=72
24x2=48
