Savannah recorded the average rainfall amount, in inches, for two cities over the course of 6 months.City A: {4, 3.5, 5, 5.5, 4, 2}
City B: {5, 6, 3.5, 5.5, 4, 6}
(a) What is the mean monthly rainfall amount for each city?
(b) What is the mean absolute deviation (MAD) for each city? Round to the nearest tenth.
(c) What is the median for each city?

Answers

Answer:

City A: {2, 3.5, 4, 4, 5, 5.5}

City B: {3.5, 4, 5, 5.5, 6, 6}

Mean is the average.

Average of City A = 4 (2+3.5+4+4+5+5.5 = 24 and 24/6 = 4)

Average of City B = 5 (3.5+4+5+5.5+6+6 = 30 and 30/6 = 5)

Mean Absolute Deviation

Mean Absolute Deviation of City A = 0.8

Mean Absolute Deviation of City B = 0.8

Median is the middle (after putting it in order least to greatest)

Median of City A = 4

Median of City B = 5.25 (5+5.5 = 10.5 and 10.5/2 =5.25)

A certain social site has grown rapidly, Accerding to one repart, about 6 million users were added each day, How many users were added, on average, each second? (Round your answer to the nearest integer.) users/second elook

Answers

Answer:

69 users.

Step-by-step explanation:

First, we need to calculate the amount of seconds in one day.

a) Each hour has 60 minutes and each minute has 60 seconds.

Therefore, one hour has (60)(60) = 3600 seconds.

b) Since the day has 24 hours, we are going to multiply the total amount of seconds per hour by 24.

3600 (24) = 86400 seconds per day.

c) Now that we have the amount of seconds per day, we are going to divide the total amount of users added each day by the amount of seconds per day.

6000000/86400 = 69.44 users per second.

Therefore, 69 users are added, on average, each second.
