Answer:
question 7 would be option 4 because its saying he has AT LEAST $5, which would mean he DOES have $5 or more. Which is why you would use the "more than or equal to" sign that was used in option 4.
question 8 would be option 1 because its a closed circle that includes the $5 and its going to the right.
Step-by-step explanation:
0.8 is the simplified answer I believe.
Answer:
0.0492
Step-by-step explanation:
Based on the tree diagram we need to tell the the probability that the test for lice returns a false positive. False positive means that the student has no lice but still the test shows a positive result.
So for this we have to first look for the branch, from the starting node, which shows that student has no lice. From the starting point, the upper branch represents the students that have lice and lower branch represents the students who have no lice. So, we will consider the lower branch with probability mentioned as 0.82
Now, the lower branch is divided into two branches further. We have to look for the branch which shows positive test result. This would be the upper branch with probability mentioned as 0.06.
The overall probability of this event is mentioned at the end of the branch which is 0.0492
This is the probability of the combined event: Student has no lice but tests shows positive result which is the False positive.
Thus, the probability that the test for lice returns a false positive is 0.0492
Two conditionals from each biconditional are
- (1) A month has exactly 28 days (2) It is February
- (1)Two angels are complementary (2) The measures of the angles add up to 90
- (1) The area of square s^2 (2) The perimeter of the square is 4s
<h3>How to write two conditionals from each biconditional?</h3>
A biconditional statement is represented as:
if and only if p, then q
From the above biconditional statement, we have the following conditional statements
Conditional statement 1: p
Conditional statement 2: q
Using the above as a guide, the conditional statements from the biconditional statements are:
<u>Biconditional statement 30</u>
- A month has exactly 28 days
- It is February
<u>Biconditional statement 31</u>
- Two angels are complementary
- The measures of the angles add up to 90
<u>Biconditional statement 32</u>
- The area of square s^2
- The perimeter of the square is 4s
