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)
First, you want to put all the numbers in order from least to greatest.
21, 33, 33, 42, 67, 79, 89
Now, you can use this song to help remember how to do these problems.
Cross off the sides till you get to the center. 1 is good, 2 is bad. (If you get two numbers in the middle) add then divide by two.
Cross off 21, then 89, then 33, then 79, then 33, then 67. Now, you're left with 42 in the middle. That is your median. Hope this helps! :)
The perimeter of the square will be 22
Answer:
50% of 100<75% of 104
50% of 100>75% of 60
Step-by-step explanation:
For the inequality to support the statement, we can use 50% of 100 which is 50
Now we need to find "any other number" that is greater. I'll use 104 since it divides evenly. 75% of 104 is 78, 50<78
Now for the second one, we can use 50% of 100 again which is 50.
This time we need to find another number that is less than. I'll use 60. 75% of 60 is 45. 50>45
90 + 50 = 140
140 - 7 = 133
130 - 140
