Answer:
Step-by-step explanation:
1. You have the following formula for calculate the area of the original circular chip:
Where D is the diameter of the circle.
2. Then, if the diameter of the original circular chip is doubled (2D) to use in a new board game, the area of the new chip can be calculated with the following formula:
The number of hours it takes Elisabeth to read 3/4 of the book is; 5³/₅ hours
<h3>What are mixed numbers?</h3>
We are told that she reads 15 of her books in 112 hours.
Thus, number of hours to read one book is;
112/15 hours per book
Therefore, number of hours to read ³/₄ of the book is;
³/₄ * ¹¹²/₁₅ = 28/5
As a mixed number is 5³/₅ hours per book

Answer:
0.8015 = 80.15% probability that the student has the flu
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: Has high temperature.
Event B: Has the flu
Probability of a student having high temperatures:
90% of 35%(have the flu)
12% of 100 - 35 = 65%(do not have the flu). So
Probability of having high temperatures and the fly?
90% of 35%, so
If a student has a high temperature, what is the probability that the student has the flu?
0.8015 = 80.15% probability that the student has the flu
