(f+g)x = f(x)+g(x)

Therefore,

$\frac{x}{4} - 3 + {4x}^{2} + 2x - 4 \\ 4 {x}^{2} + ( \frac{x}{4} + \frac{8x}{4} ) - 7 \\ 4 {x}^{2} + \frac{9x}{4} - 7$

Therefore, the answer is B.

Answer:

Step-by-step explanation:

Given

See attachment for chart

Required

Number of off days

To do this, we simply calculate the expected value of the chart.

This is calculated as:

$E(x) = \sum x * f$

Where

x = days

f = chances

So, we have:

$E(x) = 0* 0.3 + 1 *0.2 + 2 * 0.25 + 3 * 0.2 + 4 * 0.02 + 5 * 0.01 + 6 * 0.01 + 7 * 0.01$

$E(x) = 1.56$

$E(x) \approx 2$
