Hello!
The mean is the average
You find the average by adding the values and dividing the sum by the amount of numbers add
2 + 5 + 9 + 11 + 17 + 19 = 63
Divide the sum by the amount of numbers added
63/6 = 10.5
The mean is 10.5
The median is the number in the middle
The two numbers in the middle are 9 and 11
When you have two numbers in the median you take the average
11 + 9 = 20
20/2 = 10
The median is 10
The answer are mean is 10.5 and median is 10
Hope this helps!
Step 1
<u>Find the slope of the line PQ</u>
we know that
the formula to calculate the slope between two points is equal to
we have
substitute the values
Step 2
Find the equation of the line that passes through point R ans is parallel to line PQ
we know that
If two lines are parallel, then their slopes are the same
The equation of the line into point-slope form is equal to
we have
substitute the values
Step 3
we know that
The point on the y-axis that is on the line is equal to the y-intercept of the line
The y-intercept is the value of y when the value of x is equal to zero
so
For find the value of y in the linear equation
The point that is on the y-axis is
therefore
<u>the answer is the option A</u>
see the attached figure to better understand the problem
Rationalizing the denominator involves exploiting the well-known difference of squares formula,
We have
so that
Rewrite 16 and 32 as powers of 2, then simplify:
So we have <em>A</em> = 8, <em>B</em> = 2, <em>C</em> = 4, and <em>D</em> = 7, and thus <em>A</em> + <em>B</em> + <em>C</em> + <em>D</em> = 21.
Answer:
x=-7,5
Step-by-step explanation:
Answer:
y < - 8
Step-by-step explanation:
Given
- 6 + y < - 14 ( add 6 to both sides )
y < - 8
