Answer 4

The manager of a factory collected data in order to analyze the relationship between the number of hours of training a worker receives and the worker's error rate. The line of best fit for the collected data is y equals 0.1 minus 0.005 x, where x is the number of hours of training a worker receives and y is the error rate.

What approximate error rate should the manager expect for a worker who receives 6 hours of training?

Answer options with 4 options
A.
0.01

B.
0.07

C.
0.13

D.
0.17

Answer 5

[AI-generated answer — Bot GPT 3.5]

To find the approximate error rate for a worker who receives 6 hours of training, we substitute x = 6 into the equation y = 0.1 - 0.005x.

y = 0.1 - 0.005(6)
y = 0.1 - 0.03
y = 0.07

So, the error rate for a worker who receives 6 hours of training is approximately 0.07.

Therefore, the answer is:

B. 0.07

Answer 7

[AI-generated answer — Bot GPT 3.5]

To find the number of Marines who volunteered, we first need to calculate the number of volunteers for each of the options based on the given percentages:

Army: 25% of 300 people = 0.25 * 300 = 75 people
Marines: 10% of 300 people = 0.10 * 300 = 30 people
Air Force: 35% of 300 people = 0.35 * 300 = 105 people
Navy: 30% of 300 people = 0.30 * 300 = 90 people

So, the number of Marines who volunteered is 30.

Therefore, the answer is:

B. 30

Answer options with 4 options
A.
1 and one-fourth hours

B.
1 and one-half hours

C.
2 hours

D.
4 hours

Answer 11

[AI-generated answer — Bot GPT 3.5]

To find the difference between the length of the shortest movie and the length of the longest movie, we look at the values on the line plot:

The shortest movie length is at 1 and one-fourth hours.
The longest movie length is at 2 and three-fourths hours.

Difference = (2 and three-fourths) - (1 and one-fourth)
Difference = 2.75 - 1.25
Difference = 1.5

So, the difference between the length of the shortest movie and the length of the longest movie is 1 and one-half hours.

Therefore, the answer is:

B. 1 and one-half hours
