Mean, Mode, Median, Range, Standard Deviation.
Step-by-step explanation:
The completed sentences are as follows -
- The arithmetic average of a distribution of scores is the Mean
- The score that shows up most often is the Mode
- The score right in the middle of a distribution is the Median
- We determine how much scores vary around the average in a way that includes information about the Range of scores by using the Standard Deviation
Answer:

Step-by-step explanation:

Add 7x to both sides:

Subtract 7 from both sides:

Divide both sides by 8:

Answer:
4 is the real number in that complex number
Answer:
Let's solve by eliminating x. Since 18 is the lowest common multiple , let's multiply the first equation by 3 and the second by -2.
18x−21y=24
−18x+10y=−2
Add the two equations.
−11y=22
Divide by -11 to isolate y.
y=−2
Substitute y=−2 into either of the 2 equations, I'll just use the second one.
9x+10=1
9x=−9
x=−1
