<u>The population in this setting is(A) All customers who have purchased something in the last year.</u>
<u></u>
Step-by-step explanation:
As it is given in the question that 1000 customers from the list of the customers who made a purchase last year.So the list refers to the population of the people who have made a purchase last year .
The 1000 customers are the sample of the population.
Answer:
9.48
Step-by-step explanation:
Add:
$29.99 + $15.00 + $9.75 = $54.74
Subtract:
$54.74 - $40.00 = $14.74
Subtract:
$14.74 - 5.26 = $9.48
Answer: $9.48
Answer:
f'(N) = a(k² - N²)/(k² + N²)
The function increases in the interval
(-k < N < k)
And the function decreases everywhere else; the intervals given as
(-∞ < N < -k) and (k < N < ∞)
Step-by-step explanation:
f(N)=aN/(k²+N²)
The derivative of this function is obrained using the quotient rule.
Then to determine the intervals where the function is increasinumber and decreasing,
The function increases in intervals where f'(N) > 0
and the function decreases in intervals where f'(N) < 0.
This inequality is evaluated and the solution obtained.
The solution is presented in the attached image.
