Answer:

A. f(x)=(x+6)(x+2)(x-3)

Step-by-step explanation:

The zeros or roots of a function are the numbers that when they are entered into the function the output will be 0.

We will evaluate the given numbers (-6,-2,3)to see in wich option all of them wil give us 0 in the output, Let´s start with the first option A) as follows:

f(-6)=((-6)+6)((-6)+2)((-6)-3)=(0)(-4)(-9)=0

f(-2)=((-2)+6)((-2)+2)((-2)-3)=(4)(0)(-5)=0

f(3)=((3)+6)((3)+2)((3)-3)=(9)(5)(0)=0

As we can see this is the correct option in which all of the values give us the output 0 adn we dont need to evaluate the resto of the options (B), C) and D))

A local mattress manufacturer wants to know if its manufacturing process is in or out of control and has hired you, a statistics
balandron [24]

Answer:

a. 95.4

b. UCL = 96.07

LCL = 94.73

c.  Process is in control

Step-by-step explanation:

a. The computation of estimate mean is shown below:-

Estimate\ mean = \frac{\Sigma X}{N} \\\\ = \frac{1908.000}{20}

= 95.4

b. The computation of Upper Control Limit (UCL) and the Lower Control Limit (LCL) for the manufacturing process is shown below:-

UCL = Mean + \frac{3\times \sigma }{\sqrt{Sample\ size} }

UCL = 95.4 + \frac{3\times (0.5)}{\sqrt{0.5} }

= 95.4 + 0.67082

= 96.07

UCL = Mean - \frac{3\times \sigma }{\sqrt{Sample\ size} }

UCL = 95.4 - \frac{3\times (0.5)}{\sqrt{0.5} }

= 95.4 - 0.67082

= 94.73

c. The explanation is shown below:-

From the above calculation we can see that the sample lies between LCL AND UCL that is (94.73 ,96.07) ,  

The Process is in control
