The maximum number of batches of cookies he can make is 3
Solution :
Given the average range of the holes drilled = 0.10 cm
The average diameter of the holes drilled = 0.25 cm
The sample size = 4
For the sample size of 4, the factor for control limit for the range () = 2.28 (From the table of constants for X-bar and R-chart)
The upper control limit for the R-chart = R-bar x
= 0.10 x 2.28
= 0.228
Therefore, the answer is greater than 0.202 but less than or equal to 0.302
Yes it is A. I had the same question.
Complete question is;
An advertising banner has four sections, as modeled in the attached image. Two sections are congruent trapezoids, and two sections are congruent right triangles. Which measurement is the best estimate of the area of the banner in square meters?
Answer:
6 m²
Step-by-step explanation:
Since we are told that there are two congruent trapezoid, it means that they will have same base of 1m.
This Means the total base of the entire triangle will be;
Base = 1 + 1¾ + 1 + 1¾ = 5.5 m
Height of main triangle = 2 m
Thus,
Area = ½ × 5.5 × 2 = 5.5 m²
We are looking for best estimate, so let's approximate to the nearest whole number to get 6 m²
3(4h+3d=18.25)-2(6h+4d=26.50)
12h+9d-12h-8d=54.75-53
d=1.75, use either original equation to solve for h...
4h+3(1.75)=18.25
4h+5.25=18.25
4h=13
h=3.25
So the cost of one hamburger and one drink is:
3.25+1.75=$5.00
