Step-by-step explanation:
Step 1: Calculate the mean. Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations. Step 3: Add those deviations together. Step 4: Divide the sum by the number of data points.
Answer: The symbol is < for both
Answer:
c=0
Step-by-step explanation:
x² + 11x + 0 = y
x² + 11x + 0 = 0
U already know that y=0 by looking at the equations above,
But your worksheet never state "c", so we will take that c is 0 (look at the equations above.)
So c is just 0.
Answer:
x = 35
Step-by-step explanation:
First, we need to add the angles on a straight line and subtract them by 180 (because angles on a straight line adds up to 180)
56 + 51 = 107
180 - 107 = 73
Now that we have found the angle of y, we can find the angle of x now. Because angles in a triangle adds up to 180, we have to add 72 and 73 now.
72 + 73 = 145
And now subtract it from 180
180 - 145 = 35
So x = 35
