Answer:
(Frequency of the value being measured divided by the total frequency) times by 100
Answer: 4x10^2
Step-by-step explanation:
<span>To find StDev, we first have to find the mean of the squared differences. The differences between each score and the mean are 0,-2,2, respectively, giving squared values of 0,4,4. To find the variance, we take the sum of the three values and divide it by the number of values in the total set (3). This gives 8/3 or 2.6667. To find the population StDev, then, take the square root of the variance (2.6667), to find 1.633.</span>
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.
