Answer:
The distance between the points is approximately 6.4
Step-by-step explanation:
The given coordinates of the points are;
(2, -2), and (6, 3)
The distance between two points, 'A', and 'B', on the coordinate plane given their coordinates, (x₁, y₁), and (x₂, y₂) can be found using following formula;
Substituting the known 'x', and 'y', values for the coordinates of the points, we have;
Therefore, the distance between the points, (2, -2), and (6, 3) = √(41) ≈ 6.4.
So you have to solve for "donation" - so let's call that X. And the things we know are what the grandfather donated, as a function - meaning based upon - Theo's donation. We'll call that Y.
So Y is equal to 1/2 of $4 plus Theo's donation...... 0.5*(x+4).
So... 4.25 = 0.5(X+4), solving for X
4.25=0.5x + 2
-2 -2
2.25=0.5x - divide each side by 0.5 to get x alone.
x = 4.50
Plugging back in:
(4.50 + 4.00)*0.5 = 4.25!
1/5 is the value but all you do is take the first number which would be your numerator and add both the first and last number together to get your denominator
Answer:
22
Step-by-step explanation:
Normal Distributions are the most important in statistics. They are also know as "bell curves".
There are special properties of Normal Distributions. I name 3 of them below:
1. Normal distributions are symmetric about their mean.
2. The area under the normal curve is 1
3. The mean, mode, and median of normal distribution are equal
This question can easily be solved using property #3 in the stated above properties.
The mean and median of normal distribution are equal. Since mean is given as 22, the median will also be 22.
