Answer:
1/4 -or- 4
Step-by-step explanation:
take the x-axis value 16 and divide by the other x-axis value, 4.
Answer:
The variance of these investment returns is 74
Step-by-step explanation:
Given:
Series = 10, 30, 15, 5, 20
To Find:
variance of a series = ?
Solution:
The variance of the series = 



Now

= 
= 36 + 196 +121 + 1+ 16
= 370
Now
= 74
Answer:
x = -8/3
y = 5
Step-by-step explanation:
Finding the equation of the line:
y = 3x +c
Substituting (-2,5) into 'y=3x+c':
5 = -6 + c
c = 11
Hence,
y = 3x + 11
For finding x:
Substituting (x, 3) into 'y = 3x +11':
3 = 3x + 11
3x = -8
x = -8/3
For finding y:
Substituting (-2, y) into 'y = 3x + 11':
y = -6 + 11
y = 5

Answer:
The solution would be (6, 2)
Step-by-step explanation:
In order to solve this using elimination, simply add the two equations together.
2x + 3y = 18
3x - 3y = 12
-----------------
5x = 30
x = 6
And now that we have the value for x, we can solve for y.
2x + 3y = 18
2(6) + 3y = 18
12 + 3y = 18
3y = 6
y = 2
Answer:
D) (10,22)
Step-by-step explanation:
based on given slope and point, the linear equation is <em>y = 9/5x + 2</em>
plugging in x-and-y values only results in a true statement for option D
example:
22 = 9/5(10) + 2
Does 22 = 18 + 2? Yes
