Left to Right<u> </u>

<u>Algebra I</u>

Coordinates (x, y)

<u>Algebra II</u>

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (-1, -3.75)

Point (-1, 4.5)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$

A car painting company has determined that the painting time of cars is uniformly distributed between 25 and 105 minutes. What i

Masteriza [31]

Answer:

$P=\frac{5}{16}$

Step-by-step explanation:

For a uniform distribution we have to:

$P (X\leq x) =\frac{x-a}{b-a}$ for x∈ (a, b)

$P (X\leq x) =0}$ for $x\leq a$

$P (X\leq x) =1}$ for $x\geq b$

In this case we have to:

a = 25 min and b = 105 min

We want to find:

$P (40 \leq X \leq 65)$

Then

$P (x_1 \leq X \leq x_2) = P(X \leq x_2) - P(X \leq x_1)$

$P (x_1 \leq X \leq x_2)= \frac{x_2 -x_1}{b-a}$

In this case:

$x_2 = 65\\\\x_1=40$

Therefore:

$P (40 \leq X \leq 65)=\frac{65 -40}{105-25}$

$P (40 \leq X \leq 65)=\frac{25}{80}$

$P (40 \leq X \leq 65)=\frac{5}{16}$
