The mean is the average, which is adding all the numbers up and dividing by how many numbers there are. There are 2x(1), 3x(2), 9(3), 9(4), and 5(5).
2+6+27+36+25 = 96.
There were 28 total.
Divide 96 by 28. 3.4 is the average.
The median is the middle number from least to greatest.
3.5 is the median.

crimeas [40]
If you subtract 14 from the total of 96, then you get 82. Take half of 82, and you get the number of cars washed in spring: 41!

A company determines that monthly sales​ S(t), in thousands of​ dollars, after t months of marketing a product is given by ​S(t)
patriot [66]

Answer: a) S'(1) = 136; S'(2) = 104; S'(4) = 76;

b) S''(1) = -38; S''(2) = -26; S''(4) = -2

Step-by-step explanation:

a) S' means first derivative;

\frac{d}{dt}(6t³ - 45t² +180t +130) = 6t² - 50t + 180

S'(1) = 6.1² - 50.1 + 180

S'(1) = 136

S'(2) = 6.2² - 50.2 + 180

S'(2) = 104

S'(4) = 6.4² - 50.4 + 180

S'(4) = 76

b) S'' is the second derivative of S:

\frac{d^2}{dt^2}(6t² - 50t + 180) = 12t - 50

S''(1) = 12.1 - 50

S''(1) = -38

S''(2) = 12.2 - 50

S"(2) = -26

S"(4) = 12.6 - 50

S"(4) = -2

c) Derivative is the rate of change of a function. The first derivative is the slope of the tangent line to the graph if the function in a determined point, while the second derivative measures how the rate of change is changing.

Analysing the values, we can conclude that the sales of the product after t months is decreasing at a rate of 12.
