The sum of all exterior angles for every shape is 360 so just divide 360 by the measurement of one exterior angle (18) to get 20
Answer:
7/6
Step-by-step explanation:
Answer:
4/9
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator
GCD of 16 and 36 is 4
Divide both the numerator and denominator by the GCD
16 ÷ 4
36 ÷ 4
Reduced fraction:
4
9
Therefore, 16/36 simplified to lowest terms is 4/9.
Answer:
B
Step-by-step explanation:
Data set D does not contain the value 128, which is the median value.
Data set C does not contain the outlier value 91.
Data set A contains value 168, which does not show up on the plot.
The only remaining choice is B.
_____
In order, the data values of set B are ...
... 91, 114, 120, 126, 128, 128 134, 136, 139, 142, 152
The median value of these 11 is the 6th one: 128. The median values of the remaining two sets of 5 are 120 and 139, making these values the quartiles at the ends of the box. The value 91 is more than 1.5 times the IQR (19) below the 1st quartile, so is considered an outlier. (The cutoff is 120-1.5·19=91.5.)
The answer is A. one of the zeros is x = -1
