Actually Welcome to the Concept of the Probability.
Basically we have to know that, when there is a specific event for which a probability has to be done, there are always two possibilities that is,
Event favourable and Not Favourable.
the Sum of both always end up as 1.
thus sum of the probability distribution is 1.
8x5=40
So the car is 40 inches long
Find out the value of z
Remember that
z =(x - μ)/σ
we have
μ=18
σ=5
For x=5
substitute
z=(5-18)/5
z=-2.6
Using a z-scores table
we have that
P(x ≥ 5)=0.99534
therefore
<h2>the answer is option A</h2>
In a positive correlation, both variables increase together. An example of this is a company's profit's relationship with its sales. The greater the sales, the greater the profit.
A negative correlation is where one variable decreases with increase in the other. An example is the time taken to reach somewhere and the speed traveled at. The faster you move, the less the time.
No correlation means the two variables are not related. An example of this is as you get older, it does not mean you will get better grades.
