Answer:
Mark is 30 and Teri 36
Step-by-step explanation:
I suck at explaining things but here's and answer :)
Yes. If you have very high or very low outliers in your data set, it is generally preferred to use the median - the mid-point when all data points are arranged from least to greatest.
<span>A good example for when to avoid the mean and prefer the median is salary. The mean is less good here as there are a few very high salaries which skew the distribution to the right. This drags the mean higher to the point where it is disproportionately affected by the few higher salaries. In this case, the median would only be slightly affected by the few high salaries and is a better representation of the whole of the data. </span>
<span>In general, if the distribution is not normal, the mean is less appropriate than the median.</span>
Answer:
10x + 12 is your expression :)
Step-by-step explanation:
10*x + 12 = 10x + 12
Supplementary: Angles that add up to 180 degrees.
This means that angle 1 and angle 2 add up to 180 degrees. You can put them into an algebraic problem like I have in this (the image I have added), and solve for what x is. That is the key to finding out what angle 1 equals!
Once you have found x you can plug it into the equation you have for angles 1 and 2 to find if they equal 180.
Hope this helps!
Answer:
1. x = 47
2. x = 156
3. x = 62
4. x = 58
Step-by-step explanation:
1. 180 - 133 = 47
2. 180 - 24 = 156
3. 28 + 90 = 118. 180 - 118 = 62
4. 32 + 90 = 122. 180 - 122 = 58
