Answer:
The median because it is unaffected by outliers.
Step-by-step explanation:
While mean is one of the most well known and used central tendency measurements, it has some weaknesses. Mean will show inaccurate data if there are outliers that have a very huge/small value. Income is one of the things that can hugely vary among people. A billionaire can pull the data up and make the mean show result that higher than it should be. In this case, the median is better to show the data. The mode is used for nominal data, while income is ordinal.
Answer:
.74
Step-by-step explanation:
First, you know that 30% are boys and 70% are girls. Then, take 60% of 30% and 70% of 80%. From there you get .74 as the probability of a randomly chosen child having taken a car to school.
Answer:
1/20 or 0.05
Step-by-step explanation:
Assuming that all five posters are different, the number of ways to randomly place those posters is given by:
If we want the largest to be in the center and the next largest to be on its left, two poster will have a set position and only three could be randomized:
Therefore, the probability is:
The probability is 1/20 or 0.05.
Answer:
C.
Step-by-step explanation:
So basically set (10x-13) equal to (3x+22) and then solve for x
x=5
Plug 5 into the equations
(10(5)-13)=37
(3(5)+22)=37
These two angles are congruent due to the triangle being isosceles
37+37=74
All angles in a triangle are equal to 180 degrees
Therefore 180-74=106
Angle JKL= 106 degrees
Hope this helps :)
