Answer:
a = 7
Step-by-step explanation:
I think, what you need to do, is first understand how to find the mean of anything: It's quite simple, actually, just add up all the numbers, then divide that number by the number of numbers. So, let's put it in perspective:
10, 3, 4, a, 6, 9, 10
7 is the mean. 7 is the number of numbers.
If, to find the mean is: 10 + 3 + 4 + a + 6 + 9 + 10= 7a ÷ 7, then: 10 +3 + 4+ 6 + 9 +10= 42
42 plus what divided by 7 is the question now.
42 + a ÷ 7= 7
So, 7 times 7, that's 49 minus 42 and you've got your answer: 7

Answer:
6
Step-by-step explanation:
You will recognize that these points both have the same x-coordinate, so are on the vertical line x=2. The distance between them will be the difference of the y-coordinates:
6 - 0 = 6
The points are 6 units apart.
__
If you like, you can use the distance formula.
d = √((x2 -x1)² +(y2 -y1)²)
The values of these parameters are ...
x1 = 2, y1 = 0
x2 = 2, y2 = 6
Then the distance is ...
d = √((2 -2)² +(6 -0)²) = √(0 +36) = 6
The distance between the points is 6 units.
