You roll a fair 666-sided die. What is \text{P(not }3)P(not 3)start text, P, left parenthesis, n, o, t, space, end text, 3, righ

prohojiy [21]

Answer:

$P(Not\ 3) = \frac{5}{6}$

Step-by-step explanation:

Given

$S = \{1,2,3,4,5,6\}$ --- sample space

Required

P(not 3)

First, we list out all outcomes that are not 3.

We have:

$Not\ 3 = \{1,2,4,5,6\}$ --- 5 possible outcomes

$S = \{1,2,3,4,5,6\}$ ---- 6 total outcomes

So, P(Not 3) is calculated as:

$P(Not\ 3) = \frac{n(Not\ 3)}{n(S)}$

$P(Not\ 3) = \frac{5}{6}$

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation.

kotegsom [21]

Answer: $(-9, 16]$

This is the interval from -9 to 16. Exclude -9 but include 16.

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

Work Shown:

The idea is to multiply all sides by 5, then add 1 to all sides

$-2 < x \le 3$

$5(-2) < 5x \le 5(3)$

$-10 < 5x \le 15$

$-10+1 < 5x+1 \le 15+1$

$-9 < 5x+1 \le 16$

This converts to the interval notation $(-9, 16]$

note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.

What is the simplified form of ?

Natalija [7]

Let's set it up like this:
$\frac{\frac{x}{3}-\frac{y}{4}}{\frac{x}{4}+\frac{y}{3}}$
Find the LCD, which is 12, and adjust them according to that.
$=\frac{\frac{4x-3y}{12}}{\frac{3x+4y}{12}}$
Divide.
$=\frac{\left(4x-3y\right)\cdot \:12}{12\left(3x+4y\right)}$
Cancel the common factor, which is 12.
$=\frac{4x-3y}{3x+4y}$
That would be our answer!

Let me know if you have any questions regarding this problem!
Thanks!
