Answer:
3.00
Step-by-step explanation:
USL = 350+18 = 368
z = (USL-Mean)/6*σ = (368-350)/6*σ
σ = 3/0.9999966 = 3.00 (approx)
Answer:
Step-by-step explanation:
<u>Given equation:</u>
<u>Solve for x, divide both sides by 3yz:</u>
- 3xyz/3yz = P/3yz
- x = P/3yz
Correct choice is C

Answer: 40
Step-by-step explanation:
because I just had that on my math test and got it wrong
6x - y = 31 so y = 6x - 31
substitute y = 6x - 31 into 3x + 7y = 8
3x + 7y = 8
3x + 7(6x - 31) = 8
3x + 42x -217 = 8
45x = 225
x = 5
y = 6x - 31
y = 6(5) - 31
y = 30 - 31
y = -1
answer
x = 5 and y = -1
