Lubov Fominskaja [6]

Answer:

The answer is "0.6227 and 0.5971".

Step-by-step explanation:

$\to p(x\leq 2)=p(0)+p(1)+p(2)$

$=e^{-2.2}(1+2.2^{1}+\frac{2.2^2}{2!})\\\\=0.6227$

$\to x \sim emp(\frac{1}{2.2})\\\\\to f(x)=\frac{1}{2.2} emp1-\frac{x}{2.2}$

$\to p(x \leq 2)=\int^{2}_{0} \frac{1}{2.2} emp1(-\frac{x}{2.2}\ dx$

$=1-emp1-2|2.2\\\\=0.5971$

Answer: Choice C

Closed filled in circle at -3; shading to the right.

========================================================

Explanation:

Follow the steps shown below to isolate x. Note that the inequality sign flips when we divide both sides by a negative number.

$-4x+8 \le 20\\\\-4x \le 20-8\\\\-4x \le 12\\\\x \ge 12/(-4)\\\\x \ge -3\\\\$

Here's another way to isolate x

$-4x+8 \le 20\\\\8 \le 20+4x\\\\4x+20 \ge 8\\\\4x \ge 8-20\\\\4x \ge -12\\\\x \ge -12/4\\\\x \ge -3\\\\$

The inequality sign flip happens much earlier when we go from the format of $A \le B$ to $B \ge A$ (in step 3)

The graph of this will have a closed filled in circle at -3, then shading to the right to describe all values -3 or larger.

This is why we go for choice C.
