➷ Equations come in the form y = mx + c
'c' is the y intercept
In this equation, the y intercept is -3

We start by showing the position of the first quartile, Q1 on the normal distribution graph. Q1 happens at 25% of the data.
The graph is shown below
We are interested in the area to the left of Q1 and we know that the probability is 0.25
We can find out the value of z-score from the table as shown below
The z-score when p=0.25 is 0.68
then changing this z-score into the actual value


Answer:
B. 65 sq. inches
Step-by-step explanation:
(5×5)+(4×½×5×4)
= 25+40
= 65 sq. inches
Answer:
Where:
And we can find the intercept using this:
On this case the correct answer would be:
E. none of the above
Since the intercept has no association between the increase/decrease of the dependent variable respect to the independent variable
Step-by-step explanation:
Assuming the following options:
A. there is a positive correlation between X and Y
B. there is a negative correlation between X and Y
C. if X is increased, Y must also increase
D. if Y is increased, X must also increase
E. none of the above
If we want a model
where m represent the lope and b the intercept
Where:
And we can find the intercept using this:
On this case the correct answer would be:
E. none of the above
Since the intercept has no association between the increase/decrease of the dependent variable respect to the independent variable
