Answer:
or 26.19%
Step-by-step explanation:
If the range of possible numbers is between 12 and 54 then that means that there are 42 (54 - 12) possible numbers that can be made. In this range, there are 11 prime numbers which are the following...
13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53
Therefore, the probability that the number formed is a prime would be
which if we divide and multiply the decimal by 100 we get the probability in percentage form.
= 0.2619
0.2619 * 100 = 26.19%
Finally, we can see that the probability of this happening is 26.19%
V = 48
A square pyramid is a polyhedron with a square base and 4 triangular faces. All the triangular faces meet at a single point called the apex. The faces of the pyramid connect the bases with the apex. Volume of a Square Pyramid is the measure of the number of units occupied by the pyramid.

The average score of all the students in both classes is 84.
<h3>How to calculate the average?</h3>
The class with 30 students had an average score of 80 on a test. The total score will be:
= 30 × 80
= 2400
A class with 20 students had an average score of 90 on the same test. The total score will be:
= 20 × 90
= 1800
Total scores = 2400 + 1800 = 4200
Number of students = 20 + 30 = 50
The average score will be:
= Total score / Total students
= 4200 / 50
= 84

Answer:
The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value.

I attached an Image you can visualize it clearly
P.S I ain't that good at drawing though :P
