Answer:
Step-by-step explanation:
The equation of a circle with radius r and center (h, k) is:
This circle has center (-7, -4) and radius 2.
The equation is:
Let
S = sum of the data values
n = number of data values
The mean M is equal to
M = S/n
since you add up the values and divide by n. We don't need to know what S or n are.
If we add 5 to each data value, then we're adding on n copies of 5, or 5n
The new mean N is
N = (S+5n)/(n)
N = (S/n) + (5n/n)
N = M + 5
The new mean is a result of taking the old mean M and adding on 5
So,
N = M+5
N = 10+5
N = 15
The standard deviation will remain the same because each data value hasn't moved in relation to one another. Every data value has been shifted up the same amount. For instance if A and B are two points in this data set, then A+5 and B+5 will be the same distance away. Apply this logic to any number of data values. While standard deviation isn't that simple, it still has a loose connection to "distance" of the values, or how spread out they are.
So that's why the final answer is choice C)
number 3 is your answer x<-y+4/2-4
The correct answer is clockwise 90 degrees. There are 360 degrees in a compete rotation, so if you turn it 270 degrees clockwise (that would leave you only 90 degrees to get back to where you started. If you go in the opposite direction, it will only take 90 degrees to get to that point.
