For this we simply divide the total ft. by the ft. in a mile
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:-

= 95.4
b. The computation of Upper Control Limit (UCL) and the Lower Control Limit (LCL) for the manufacturing process is shown below:-


= 95.4 + 0.67082
= 96.07


= 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
Answer:
They earned $9.60 they will each get $4.80. Give or take.
Step-by-step explanation:
9.60÷2=4.80
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,

where b is the base and h is the altitude
Thus, we have,
and 
Substituting the values in the above formula, we get,

Multiplying the terms, we get,

Dividing, we get,

Therefore, the area of the triangle is 90 m²
