Answer:
0.6154 = 61.54% probability that the student is an undergraduate
Step-by-step explanation:
Conditional Probability
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.
In this question:
Event A: Foreign
Event B: Undergraduate.
There are four times as many undergraduates as graduate students
So 4/5 = 80% are undergraduate students and 1/5 = 20% are graduate students.
Probability the student is foreign:
10% of 80%
25% of 20%. So
Probability that a student is foreign and undergraduate:
10% of 80%. So
What is the probability that the student is an undergraduate?
0.6154 = 61.54% probability that the student is an undergraduate
Your answer is 15
Good Luck
Answer:
y = 1/4x -10
Step-by-step explanation:
The equation would be y = 1/4x -10
we know that we have to set the equation up as y=mx+b
m being slope and b being y-intercept
we can see on the graph that the line intercepts the y-axis at -10, so that would be b
for slope, you can just look and count rise over run so:
it goes 10 up and 40 over which equals 10/40 also known as 1/4
hope that helped :)
Answer:
Today's temperature is 5.7 degrees above Bill's normal temperature.
Step-by-step explanation:
Given
Represent the normal temperature with N and today's temperature with T.
Such that:
Required
Determine the temperature above the normal temperature
The interpretation of this is to calculate the difference between Bill's normal temperature and Bill's today temperature.
Represent the difference with D
D is calculated as follows:
Substitute values for T and N
Hence, today's temperature is 5.7 degrees above Bill's normal temperature.
Lucy used 2 1/3 kilograms of apples for her dessert.
Get the whole fraction.
3 2/3 = ((3*3) + 2) / 3 = 11/3
1 1/3 = ((3*1) + 1) / 3 = 4/3
Original weight of apples = 11/3
Remaining weight of apples = 4/3
weight of apples used = ?
Subtracting fractions:
Step 1. Make sure the denominator are the same
11/3 - 4/3
Step 2. Subtract the numerators and put the difference above the denominator
(11 - 4) / 3 = 7/3
Step 3. Simplify the fraction
7/3 = 2 1/3
