The data below are the monthly average high temperatures for New York City. What is the five-number summary? 40, 40, 48, 61, 72,

yawa3891 [41]

Answer:

B) Sample minimum: 40, Sample maximum: 84

Q1: 45, Median: 63, Q3: 77

Step-by-step explanation:

The first step is to write the temperatures in crescent order:

40, 40, 42, 48, 54, 61, 65, 72, 76, 78, 84, 84,

The sample minimum is the lowest value = 40

The sample maximum is the highest value = 84.

Since there are 12 numbers, the sample median is the average between the 6th and 7th terms:

$M = \frac{61+65}{2}\\ M=63$

The first quartile is the average between the 3rd and 4th terms:

$Q_1 = \frac{42+48}{2}\\ Q_1=45$

The third quartile is the average between the 9th and 10th terms:

$Q_3 = \frac{76+78}{2}\\ Q_3=77$

Therefore, the answer is:

B) Sample minimum: 40, Sample maximum: 84

Q1: 45, Median: 63, Q3: 77

1. Susan decides to take a job as a transcriptionist so that she can work part-time from

IRISSAK [1]

Answer:

a) About 46.3 hours

b) About $1036.80

Step-by-step explanation:

Break even means to make enough to cover her costs.

Given her cost is 1000, we need to find how many hours she will need to cover this up.

In 1 minute, she can type 90 words, that would pay her:

0.004 per word for 90 words = 0.004 * 90 = $0.36 per minute

Susan makes $0.36 per minute, so the amount of time (in minutes) it will take her to make $1000, is:

1000/0.36 = 2777.78 minutes

Converting that to hours, we divide by 60,

2777.78/60 = 46.3 hours

4 hours per day for 3 days = 4 * 3 = 12 hours (per week)

Let there be 4 weeks in a month, so

12 hours per week * 4 = 48 hours per month

She will work 48 hours per month.

Given 90 words per minute, in 1 hour, she can type:

60 minutes * 90 = 5400 words per hour

In 48 hours, she can type:

5400 words per hour * 48 hours = 259,200 words

That would pay her:

0.004 per word for 259,200 words = 0.004 * 259,200 = $1036.80
