a quality supervisor for a factory that makes cell phone cases examines a sample of 46 cases are the wrong size in a shipment of 3,000?
A)410
B)475
C)506
D)522
No wonder you're in danger of failing. You didn't follow instructions and proofread your post. It doesn't make any sense.
well then help me plz :) is it 506?
the answer is d) 522
3000 divided by 46
multiply that number by 8
********you have to round your answer****
thanks so much!
How do you know the answer is 522? There is no 8 in the problem.
To find the answer to this question, we need to calculate the proportion of cases that are the wrong size in the shipment of 3,000.
First, divide the number of wrong-sized cases (46) by the total number of cases in the shipment (3,000).
46 / 3,000 ≈ 0.01533
Next, multiply the resulting proportion by 100 to convert it to a percentage.
0.01533 * 100 ≈ 1.533
Therefore, approximately 1.533% of the cases in the shipment are the wrong size.
Now, we need to find the answer choice that corresponds to this percentage.
A) 410
B) 475
C) 506
D) 522
Comparing the given answer choices, we see that none of the options match the percentage we calculated.
Thus, none of the given answer choices accurately represent the proportion of wrong-sized cases in the shipment.
