Answer: The required probability is
Step-by-step explanation:
Since we have given that
Number of people came into Brad's store = 48
Number of them made a purchase = 40
So, the experimental probability that the next person to come into the store will make a purchase would be
Hence, the required probability is
Answer:
See explanation below.
Step-by-step explanation:
Assuming the following function:
Where y represent the sales and t the years after a particular model is introduced.
For this case if we find the domain for this function we have this:
Since the neatural log for negative numbers or 0 is not defined.
So then
And the range on this case is all the possible reals.
The sales are equal to 0 when:
If we exponential both sides we got:
So then the x intercept is . We don't have y intercept since the function not touch the y axis.
And we don't have a relative maximum or minimum since the function is increasing over the interval of all the reals.
The plot of the function is on the figure attached.
