1 answer:
atroni [7]2 years ago

Answer:

141in^{2}

Step-by-step explanation:

Area of a trapezium = \frac{h}{2}(a + b)

h = height

a and b = upper and and lower lengths

Area of a trapezium = \frac{9}{2}(10 + 16)

 =  \frac{9}{2} × 26

 = 117in^{2}

Area of a triangle = \frac{1}{2} × base × height

 = \frac{1}{2} × 6 × 8

 =  \frac{1}{2} × 48

 = 24in^{2}

Total area = Sum of the areas of both the shapes

 = 117 + 24

 = 141in^{2}

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

Find the area of the following geometric figure
romanna [79]

The area of the triangle is 90 m²

Explanation:

Given that the base of the triangle is 15 m

The altitude of the triangle is 12 m

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

Area=\frac{1}{2}bh

where b is the base and h is the altitude

Thus, we have,

b=15 and h=12

Substituting the values in the above formula, we get,

Area=\frac{1}{2}(15)(12)

Multiplying the terms, we get,

Area=\frac{180}{2}

Dividing, we get,

Area=90 \ m^2

Therefore, the area of the triangle is 90 m²
