Answer:
a) 
b) 
Step-by-step explanation:
Let's define the following events first:
F: The event that a course has a final exam.
R: The event that a course requires a research paper
From the info provided we have that:
P(F and R) =0.32
So then we can create a Venn diagram as we can see on the figure attached.
a. Find the probability that a course has a final exam or a research project.
For this case we can find the probability like this:

b. Find the probability that a course has NEITHER of these two requirements.
For this case we can use the complement rule and we can find the probability like this:

And that's the same value obtained with the diagram.
Answer:
mean= 56
Step-by-step explanation:
I have a big brain
3/5 *45/A is the equation
therefore A would equal 5*15
which is then be 75 inches
Hey!!
here is your answer >>>
As we know, The formula for the length of a trinagle is
(1/2)(base)(height) !.
Height is 6/5 and area is 2/5, then what is the base, we will just have to substitute these values!.
which is ,
2/5 = (1/2)(base)(6/5)
2/5 = (base)(3/5)
base = (2/5)/(3/5)
base = (2/5)(5/3)
base = 2/3 ft!.
Hope my answer helps!
