Answer:
r is very close to 1 because there is a very concrete relationship between the variables x and y.
Step-by-step explanation:
Given that x = age,
y = time since the subject had acquired a driving licence.
We want to know why the correlation of these variables is so close to 1.
Correlation of these variables is the mutual relationship between the two variables.
Drivers licence is only obtainable when one comes of age.
For example: Many countries don't issue drivers license to an individual below the age of 18.
The correlation is very close to 1 because there is a concrete relationship between the variable.
Answer:
Input: -7
Step-by-step explanation:
We need to make an equation before solving for x, the input.
Output of A: x × 5 - 4 = 5x - 4
Output of B: x × 3 + 8 = 3x + 8
You know that the output of A is three times the output of B:
5x - 4 = 3(3x + 8)
Now that we have an equation, we can work out the value of x.
5x - 4 = 9x + 24
Isolate like terms.
-24 - 4 = 9x - 5x
Evaluate.
4x = -28
Find x.
x = -28 ÷ 4
x = -7

Answer:
(-2,4)
Step-by-step explanation:
Since this is a system of equations, just look where the two lines intersect.
In this case, the intersecting pair is: (-2, 4)
