Answer:

141 $in^{2}$

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

= 117 $in^{2}$

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

= $\frac{1}{2}$ × 6 × 8

= $\frac{1}{2}$ × 48

= 24 $in^{2}$

Total area = Sum of the areas of both the shapes

= 117 + 24

= 141 $in^{2}$

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
