slope formula : 
a. coordinates : (3,12) and (4,16)
b. coordinates : (1,4) and (3,12)
⇒ A. Yes. Both slopes are equal to 4
Answer:
dude if this is a whole test you shouldve studied for that not just ask people for the answer
Step-by-step explanation:
8 to 1 i think not saying its the answer though i think it is
Answer:
upper control limit = 13.34
Step-by-step explanation:
The c-chart is used to check the change in the number of recorded calls per day
First find out the center line
c = sum of recorded calls/number of days
c = (3 + 0 + 8 + 9 + 6 + 7 + 4 + 9 + 8)/9
c = 54/9
c = 6
The upper control limit for 3σ is
upper control limit = c + 3√c
upper control limit = 6 + 3√6
upper control limit = 13.34
Therefore, the upper control limit for the 3-sigma c-chart is 13.34.
