Question

A local library manager randomly surveys 80 patrons about the type of ok they borrow when the visit the library. The manager finds that 3 patrons borrow novels. If the local library has 345 patrons, approximately how many of them borrow novels when they visit the library? Round your answer to the nearest whole number.

To find out approximately how many of the 345 patrons borrow novels, we can set up a proportion using the information from the survey:

3 patrons out of 80 surveyed borrow novels
x patrons out of 345 total patrons borrow novels

3/80 = x/345

Cross multiplying, we get:
80x = 3*345
80x = 1035
x = 1035/80
x ≈ 12.94

Rounded to the nearest whole number, approximately 13 of the 345 patrons borrow novels when they visit the library.

Answer 2

U sure

Answer 3

Let's double-check the calculation:

3 patrons out of 80 surveyed borrow novels

3/80 = x/345

Cross multiply:
80x = 3 * 345
80x = 1035
x = 1035/80
x = 12.9375

Rounded to the nearest whole number, approximately 13 of the 345 patrons borrow novels when they visit the library.

Yes, the correct approximation is 13 patrons.

No problem! Feel free to provide the data whenever you're ready, and I'll be happy to help you calculate the mean times spent shopping for the two different groups. Just let me know the times for each group.

Answer 8

The table shows the times, in minutes, spent shopping by two different groups. First find the mean times each group spent shopping. Then determine the difference in the mean times. Round your answers to one decimal place.

The mean time Group A spent shopping is ___ minutes

The mean time Group B spent shopping is ___ minutes.

The mean times Group A and Group B spent shopping differ by ___ minutes.

Thank you for providing the specific questions related to the mean times spent shopping by two different groups. Please provide the time data for both Group A and Group B, and I will calculate the mean times for each group and the difference between them. This will allow me to fill in the blanks with the correct calculations.

Answer 10

Group A- 18, 20, 46, 34, 58, 31, 41

Group B- 15, 21, 32, 42, 29, 57, 39

Answer 11

[AI-generated answer — Bot GPT 3.5]

To find the mean times spent shopping for each group and determine the difference in the mean times, we will first calculate the mean for Group A and Group B using the provided data:

For Group A:
Mean time spent shopping = (18 + 20 + 46 + 34 + 58 + 31 + 41) / 7
Mean time for Group A ≈ 33 minutes

For Group B:
Mean time spent shopping = (15 + 21 + 32 + 42 + 29 + 57 + 39) / 7
Mean time for Group B ≈ 33.4 minutes

Now, we can calculate the difference between the mean times for both groups:
Difference = Mean time for Group B - Mean time for Group A
Difference = 33.4 - 33
Difference ≈ 0.4 minutes

Therefore, the answers are:
- The mean time Group A spent shopping is approximately 33 minutes.
- The mean time Group B spent shopping is approximately 33.4 minutes.
- The mean times Group A and Group B spent shopping differ by approximately 0.4 minutes.
