Answer:
The game’s expected value of points earned for a turn is 71.
Step-by-step explanation:
Here we know that:
Points Frequency
50 55
75 32
150 13
Here points earned is a random variable.
We need to find its expected value,
Finding Expected value:
Expected value of a random variable is its mean value. So we will first find the mean value of points earned per turn from the table we are given.
Total number of turns = sum of frequencies
= 55 + 32 + 14 = 100
Total points earned = 50(55) + 75(32) + 150(13)
= 7100
Expected value of points earned for a turn = Mean value of points
= Total points/no. of turns
= 7100/100
= 71
A logarithmic function without a subscript means that it must be log base 10.
When learning about logarithms, a textbook/teacher provides their students with the following general equations
Hopefully you are familiar with this. Using the equations that I just showed, we can change the equation to
This would make answer choice C correct.
The radius of a circle is the distance from the center of the circle to any point on it’s circumference. The easiest way to find the radius is by dividing the diameter in half
