ANSWER
Find out the how many 3, 4, and 5 point questions could there be.
To proof
Let us assume that the 3 points based question be = x
Let us assume that the 4 points based question be = y
Let us assume that the 5 points based question be = z
As given
An instructor wants to write a test with 25 questions
than the equation become in the form
x + y + z = 25
he quiz to be worth a total of 100 points.
than the equation is becomes
3x + 4y + 5z =100
As given
He wants the number of 3-point questions to be 4 less than the number of 4-point questions
x = y -4
Than the three equation are
x + y + z = 25 ,3x + 4y + 5z =100 and x = y -4
put x = y -4 in the x + y + z = 25 ,3x + 4y + 5z =100
than
2y + z = 29, 7y +5z= 112
multiply 2y + z = 29 by 5 and subtracted 7y +5z= 112
10 y -7y + 5y -5y = 145 -112
3y = 33
y =11
put in the x = y -4
x = 11-4
x= 7
put the value of x ,y in the x + y + z = 25
7 + 11 +z =25
18 +z = 25
z = 25 -18
z=7
therefore
numbers of the 3 point question be = 7
numbers of the 4 point question be = 11
numbers of the 5 point question be = 7
Hence proved
Answer:
86.74% probability of a Madonna University nursing student getting hired within 6 months of graduation given that they complete their degree here.
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
Compute the probability of a Madonna University nursing student getting hired within 6 months of graduation given that they complete their degree here.
In this problem, we have that:
Event A: Completing their degree there.
There is a 34.72% chance of a student interested in a nursing degree not making it through the program.
So 100 - 34.72% = 65.28% = 0.6528 probability of completing their degree. So P(A) = 0.6528.
Event B: Getting hired
86.74% chance of getting hired full time in a hospital setting within 6 months of graduation.
Completing their degree and getting hired:
Probability:
86.74% probability of a Madonna University nursing student getting hired within 6 months of graduation given that they complete their degree here.
