Answer:
297
Step-by-step explanation:
Since we have to make 9 as the whole, and 33 is the denominator to make 9, we need to multiply 9*33=297.
This makes no sense if you hear it. But trust me it is the right answer i think.
Complete question is;
Identify the type of sampling used: random, systematic, convenience, stratified, or cluster.
To estimate the percentage of defects in a recent manufacturing batch, a quality control manager at General Foods selects every 18th soup can that comes off the assembly line starting with the fifth until she obtains a sample of 40 soup cans
Answer:
Systematic Sample
Step-by-step explanation:
We are told that the quality control manager selects every 18th soup can that comes off the assembly line starting with the fifth until she obtains a sample of 40 soup cans.
Thus, the selection is from a large sample of produce.
This is synonymous with systematic sample because systematic sample can be defined as a type of probability sampling in which sample members from a larger population are selected according to a random starting point but with a set periodic interval.
This resonates with the statement in the question about selecting every 18th soup from the production assembly line.
Answer:
No
Step-by-step explanation:
X+51 + 80 + 60 = 180
X + 191 = 180
X = 180-191
... gives a negative number
Answer: 108 square inches
Step-by-step explanation:
The formula for any square is base*height/2. The formual to find the area of a square is base*height. If you draw out a square and cut it in half diagonaly, you get a right triangle. That is why you divide it by 2. (sorry if the explanation was clunky/ hard to understand)
1. You would multiply 18*12 which equals 216.
2. Divide 216 by 2. 216/2= 108.
The answer is 108. Hope this helped you:)
