The average is calculated as 60 / 4 = 15
13 - 15 = -2
17 - 15 = 2
9 - 15 = -6
21 - 15 = 6
The total of squares amounts to 4 + 4 + 36 + 36 = 80
Since this is a sample, we divide it by n - 1 (which equals 3)
The standard deviation is calculated as sqrt(80/3) = 5.16 as the final answer.
Revenue = price * quantity of backpacks
quantity of backpacks = -2p + 50
For p = 9: -2(9) + 50 = -18 + 50 = 32
thus, revenue = 9 * 32 = 288
For p = 12: -2(12) + 50 = -24 + 50 = 26
therefore, revenue = 12 * 26 = 312
For p = 12.50: -2(12.50) + 50 = -25 + 50 = 25
thus, revenue = 12.50 * 25 = 312.50 MAXIMIZES REVENUE
For p = 15: -2(15) + 50 = -30 + 50 = 20
so, revenue = 15 * 20 = 300
The answer is D. Step-by-step reasoning: We are provided with the graph of a transformed tangent function. Observing the graph, it shows an upward shift by 2 units. This indicates that the parent function has been displaced 2 units upward. Thus, the new function is of the form. Therefore, options A and C are incorrect. Additionally, a function f(x) with period P transforms into function cf(bx) with period. The graph confirms that the graphed function has. Since, has period. Therefore, the function in option B cannot possess that period. Conversely, the function in option D maintains that period.
