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
Answer:
In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a 2 . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.

Answer:
There can be a number of correct answers. One of them is the ship has traveled 25 miles in 1 hour.
Step-by-step explanation:
The distance from destination f after x hours for the ship is given by f(x)=120-25x
At the beginning, x=0, f(x)=f(0)=120
After 1 hour, f(x)=f(1)=120-25=95
So in 1 hour, the ship has traveled 120-95=25 miles.
Answer:
5
Step-by-step explanation:
When squaring the number 5 (i.e 
) the answer is 25. 
is the same thing as 5 times 5. Basically with the square root, you are going backwards, so you are therefore finding the base of it all.
