Question

10. Using your model predict the cell population after 15 hours. (MD2)a) 525b) 348c) 338d) 266Answer of 9 is B

Answer 1

In order to predict the population after 15 hours, let's use the equation y = 1.79x² - 9.92x + 11.79 with the value of x = 15, then we calculate the value of y.

So we have:

`\begin{gathered} y=1.79x^2-9.92x+11.79 \\ x=15\colon \\ y=1.79\cdot15^2-9.92\cdot15+11.79 \\ y=402.75-148.8+11.79 \\ y=265.74 \end{gathered}`

Rounding to the nearest whole number, we have a population of 266, therefore the correct option is D.
