Answer: y-3y
Step-by-step explanation: The expression -3y+y is equivalent to y-3y because both terms are the same but simply arranged in a different order; both -3y and y are in each equation.
Standard deviation is like the average range values are away from the mean/median. So if you remember box and whisker plots, It is 2 boxes with 2 lines coming from them. Where the boxes meet is the mean/median depending on what you are trying to find, and the edges of the boxes are the normal distribution of values, and the lines go out, and that's the standard deviation. The values outside of those lines are outliers. A way you can think about it, is if let's say I had 3 numbers: 7,8,9. Now the mean/median is 8, and for this the standard deviation is 1 because most numbers that are not the median/mean are 1 value from the median/mean. It is a way of measuring an element of range. I hope this helped.
Answer:
What?
Step-by-step explanation:
Answer:
measure of angle is E is 45 degrees besausw if you look closely then it is a
45,45,90, Triangle and so E is 45 degrees
measure of c = 360-45+79+134 = 102 ° degrees
