ANSWER

d. 40 units

EXPLANATION

Method 1

Perimeter is the total distance around the figure.

The perimeter is

$= 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5$

$= 40 \: units$

Method 2

The three squares together formed a rectangle with dimensions,

$w = 5 \: and \: l = 15$

$Perimeter = 2w + 2l$

$Perimeter = 2(5) + 2(15)$

$Perimeter =10 + 30$

$Perimeter = 40 \: units$

The correct answer is D.

What is the answers to the question: Which rational expression is undefined when x = 0?

Rom4ik [11]

Answer:

option D

$\frac{4x-8}{-2x^2}$

Step-by-step explanation:

An expression is undefined when you get division by zero or in simple words when denominator is zero.

Now we will solve each expression one be one by plugging value of x = 0

<h3>1)</h3><h3> $\frac{5x^2-4}{3x-3}$ </h3>

$\frac{5(0)-4)}{3(0)-3}$

-4/-3 = 4/3

<h3>2)</h3><h3> $\frac{6x^2}{9x-3}$ </h3>

$\frac{6(0)}{9(0)-3}$

0/-3 = 0

<h3>3)</h3>

$\frac{8x+6}{-x^2+1}$

$\frac{8(0)+6}{-0+1}$

6/1

6

<h3>4)</h3>

$\frac{4x-8}{-2x^2}$

$\frac{4(0)-8}{-2(0)}$

<h3>-8/0</h3><h3>undefined</h3>

With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the en

GuDViN [60]

Answer:

$P = 0.1447$

Step-by-step explanation:

Given

$n = 7000$ -- total

$d = 180$ --- defective

$r = 6$ --- selected

Required

The probability of rejecting the batch

This means that at least one of the selected piece is defected.

So, we first calculate the probability that all the selected piece are accepted.

So, we have:

$Pr = \frac{7000 - 180}{7000} * \frac{6999 - 180}{6999}* \frac{6998 - 180}{6998}* \frac{6997 - 180}{6997}* \frac{6996 - 180}{6996}* \frac{6995 - 180}{6995}$

The denominator decreases by 1 because it is a probability without replacement; 180 is subtracted from the numerator to represent the number of non-defective CDs

So, we have:

$Pr = \frac{6820}{7000} * \frac{6819}{6999}* \frac{6818}{6998}* \frac{6817}{6997}* \frac{6816}{6996}* \frac{6815}{6995}$

$Pr = 0.8553$

Using the complement rule, the probability that the batch will be rejected is:

$P = 1 - 0.8553$

$P = 0.1447$
