Question 4 is Choice A
Question 5 is Choice B
Question 6 is Choice C
Question 7 is Choice B

These are relatively simple it’s just understanding the relations of x and y values :)

Three machines A, B, and C produce 55%, 25% and 20% respectively. The percentages of defective output are 3.5%, 4.5% and 5.5%. I

pishuonlain [190]

We are given the following information concerning the three production machines;

$\begin{gathered} Of\text{ the total production;} \\ A=55\text{ \%}=0.55 \\ B=25\text{ \%}=0.25 \\ C=20\text{ \%}=0.20 \end{gathered}$

Also, we are given the percentage of defective output as follows;

$\begin{gathered} A=3.5\text{ \%}=0.035 \\ B=4.5\text{ \%}=0.045 \\ C=5.5\text{ \%}=0.055 \end{gathered}$

Therefore, if an item is selected randomly, the probability that the item is defective would be;

$\begin{gathered} P\lbrack defective\rbrack=(0.55\times0.035)+(0.25\times0.045)+(0.20\times0.055) \\ P\lbrack\text{defective\rbrack}=0.01925+0.01125+0.011 \\ P\lbrack\text{defective\rbrack}=0.0415 \end{gathered}$

ANSWER:

The probability that the item is defective would be 0.0415

The expression is simplified to give -7x^2 - 11x

<h3>What are algebraic expressions?</h3>

Algebraic expressions are expressions that contains variables, constants, factors and coefficients.

They are also made up of arithmetic operations such as addition, subtraction, multiplication, division, etc.

From the information given, we have;

(- x^2 - 5x ) - ( 6x^2 + 5x)

expand the bracket

-x^2 - 5x - 6x^2 - 5x

collect like terms

-7x^2 - 11x

Thus, the expression is simplified to give -7x^2 - 11x
