Find the mean absolute deviation (mad) for this data. (remember to show your 4 steps) 88, 72, 85, 76

Stolb23 [73]

Answer:

Step-by-step explanation:

mean=(88+72+85+76)/4=321/4=80.25

x |x-mean|

88 7.75 (88-80.25)

72 8.25 (80.25-72)

85 4.75 (85-80.25)

76 4.25 (80.25-76)

--------

OleMash [197]

Answer:

1) Velocity

$v(t) = -4\cdot t^{3}+36\cdot t^{2}$

Acceleration

$a(t) = -12\cdot t^{2}+72\cdot t$

2) Velocity

$v(t) = -4\cdot t^{3}+24\cdot t^{2}$

Acceleration

$a(t) = -12\cdot t^{2}+48\cdot t$

Step-by-step explanation:

From Physics we remember that velocity ( $v(t)$ ) and acceleration ( $a(t)$ ) are the first and second derivatives of the function position in time. That is:

1) Let $s(t) = -t^{4}+12\cdot t^{3}$ , where $t \ge 0$ . The functions velocity and aceleration are, respectively:

Velocity

$v(t) = -4\cdot t^{3}+36\cdot t^{2}$

Acceleration

$a(t) = -12\cdot t^{2}+72\cdot t$

2) Let $s(t) = -t^{4}+8\cdot t^{3}$ , where $t\ge 0$ . The functions velocity and acceleration are, respectively:

Velocity

$v(t) = -4\cdot t^{3}+24\cdot t^{2}$

Acceleration

$a(t) = -12\cdot t^{2}+48\cdot t$

Since we are given no other function, we have to assume that P(x) is the "function from part d".

The average rate of change of P(x) on the interval [60, 80] is given by
rate of change = (P(80) - P(60))/(80 - 60) = (304 -320)/20 = -0.8

The average rate of change of P(x) over [60, 80] is -0.8.

_____
Units of the rate of change are ($10k)/(1k units) = $10/unit. That is, the profit drops on average $8 per unit on that interval.
