Mathswatch Question 10019 The Stem And Leaf Diagram Shows The Ages Of People In A Cinema.

A) What Is The Range Of Ages? (__) Years

B) How Many people are represented in the diagram?
(__) People

C) What is the median age?
(__) Years Old

Please hurry up my teacher is the type to threaten kids and eat them as snacks

Range = 34 years old

No of people represented = 17 people

Median = 46 years old

Step-by-step explanation:

=>First, write out all the ages represented on the stem and leaf diagram

We have:

21, 23, 30, 32, 32, 35, 43, 44, 46, 48, 49, 49, 50, 52, 52, 53, 55

A. Ranges of years: this is the difference between the highest value in the data set and the lowest value = 55-21 = 34

B. The number of people represented on the diagram is 17. There are 17 data values in the data set.

C. Median age = the middle value in the data set.

21, 23, 30, 32, 32, 35, 43, 44, (46), 48, 49, 49, 50, 52, 52, 53, 55

The middle value is the 9th value in the data set = 46

1,645,493,059.35

step-by-step explanation:

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.
