Answer:
Option a. 1.2 is the correct answer
Step-by-step explanation:
Given the data in the question;
sample size n = 10
sub group = 6
The average of sample means x" = 3.2
Average range value R' = 0.6
the value of UCL for the R-chart = ?
To get the value of UCL for the R-chart, we say;
= D₄ × R'
from table of constants "Tabular values for x-bar and range charts
for size 6, the factor for control limits for range D₄ = 2.004
so we substitute
= 2.004 × 0.6
= 1.2024 ≈ 1.2
Hence, Option a. 1.2 is the correct answer.
Answer: 4 shirts x 3 pairs of pants x 4 ties = 4 x 3 x 4=48
so there are 48 possibilities (option 3)
Answer: Length = 11 cm
Width = 14 cm
Step-by-step explanation:
Let x = Length of the rectangle.
then, width = x+ 3
Perimeter of rectangle = 2 (length +width)
Then, Perimeter = 2 (x+x+3)
= 2 (2x+3)
Since perimeter = 50 cm

[Divide both sides by 2]

The dimensions are :
Length = 11 cm
Width = 11+3= 14 cm
