Really need to someone to break this down so I can understand it

Answer:

Slope is 4/3

Step-by-step explanation:

Slope is the derivative of the equation:

$y = \frac{1}{3} {x}^{2} - 2x + 15 \\ \\ \frac{dy}{dx} = \frac{1}{3} (2x) - 2 + 0 \\ \\ \frac{dy}{dx} = \frac{2}{3} x - 2$

At point (5, 7), x is 5:

$\frac{dy}{dx} = (\frac{2}{3} \times 5) - 2 \\ \\ \frac{dy}{dx} = \frac{10}{3} - 2 \\ \\ \frac{dy}{dx} = \frac{10 - 6}{3} \\ \\ \frac{dy}{dx} = \frac{4}{3}$

Answer:

<h2>13 years</h2>

Step-by-step explanation:

Given, 

No. of children = 5

Ages of the children = 12, 18, 13, 16 and 6 years

Therefore, 

Average age of the children

$= \frac{sum \: of \: the \: ages \: of \: children}{no. \: of \: children}$

$= \frac{12 + 18 + 13 + 16 + 6}{5}$

$= \frac{65}{5}$

= 13 years (Ans)
