Answer:
Average range(R-bar) = Sum of the sample range for each sample/number of samples = (9+8+1+8+7) /5 = 33/5 = 6.6
Sample size = 8
For a sample size of 8 the factors for control limit for range (D3) = 0.136 (obtained from table of constraints for x-bar and R chart
LCL = R-bar × D3 = 6.6 × 0.136 = 0.90
Step-by-step explanation:
1. Observe question
2. Employ Point-Slope formula
(y2 - y1)/(x2 - x1 )=
(-10-9)/(-6-9) =
-19/-15=
19/15
Slope: 19/15
Answer:
1. -6
Step-by-step explanation:
f(x)=x²-9
g(x)= x-3
1. (f+g)(2) =
(2²-9)+(2-3) = (4-9)+(2-3) = (-5)+(-1)= -6
$8 x 5 = 40
40/100 = 0.4
$8 + 0.4 = $8.4
Therefore Samantha now earns $8.4 per hour.
Answer:
You will pay $4.31
Step-by-step explanation:
I know this because a fourth of $5.75 is 1.4375 so you would round it to $1.44 and then $5.75 - $1.44 is $4.31.
So you will pay $4.31 for one milkshake.
