Answer:
a)
b)
c)
d)
Step-by-step explanation:
Let X the random variable of interest and we know that the distribution is given by:
And for this problem we can use the cumulative distribution function in order to solve the items:
Part a
We want to find this probability:
Part b
Part c
And we can calculate the probability with this difference:
Part d
Since we have a continuous distribution the the probability for an unique value would be:

Do a proportion
4/1=x/38
basically 38/4
Standard form, move the variables to the left-hand-side, leave the constant on the right-hand-side, usually the "x" comes first,
Answer:
y = 2x + 10
Step-by-step explanation:
Remember, slope-intercept form is:
y = mx + b
where m is the slope and b is the y-intercept.
To write the equation in slope-intercept form, we can just solve the equation for slope-intercept form.
y - 4 = 2(x + 3)
Distribute the 2 on the right side.
y - 4 = 2x + 6
Add 4 to both sides.
y = 2x + 10
Notice, now we have the equation in slope-intercept form.
I hope this helps. Happy studying.
