The answer is B because it’s not a straight line and x can not have an exponent of 2 bc it will make it nonlinear
If you are considering P of the permutation and combination. Then simply pit the figure 6P5 in calculator and your answer will be 720. Or if not calculator then the formula is P(n,r)= n(factorial)/ (n-r)factorial.
<u>Given</u>:
The graph shows the speed of a ball in free fall for 10 seconds.
We need to determine the constant of proportionality for the given graph.
<u>Constant of proportionality:</u>
The constant of proportionality can be determined using the formula,

Where k is the constant of proportionality.
Let us consider any of the coordinate from the graph and substitute in the formula.
Consider the coordinate (4,40) and substitute in the above formula.
Thus, we have;


Thus, the constant of proportionality is 10 meters per second squared.

Answer:
0.12
Step-by-step explanation:
Total number of questions in the book = 10
Number of questions answered correctly by Alice = 6
Number of questions answered correctly by Bob = 8
Probability of Alice answering a question correctly = 0.6
Probability of Alice answering a question incorrectly = 1- 0.6 = 0.4
Probability of Bob answering a question correctly = 0.8
Probability of Bob answering a question incorrectly = 1- 0.8 = 0.2
Probability that there exists at least one question on the test which is answered correctly by Alice but not by Bob = 0.6 *0.2 = 0.12
