Answer:
A) Histogram
Step-by-step explanation:
A) The first step would be to look at the purpose and use for each type of plotting method;
Dot Plot: Used to represent the distribution of data (for ex; #of Strawberries, Blueberries, and Raspberries.
Histogram: A histogram is used to summarize discrete or continuous data. In other words, it provides a visual interpretation of numerical data by showing the number of data points that fall within a specified range of values
Box Plot: Summerizes a set of data measured on an interval scale.
Best choice: Histogram- The reason why a histogram is the best representation of the student quartiles is because a histogram is used to summarize <u>discrete </u>or <u>continuous data</u>, and the given data is <u>discrete</u>
B)
To create your histogram you first have to create a frequency table like the one below;
On the vertical axis, place frequencies. Label this axis "Frequency".
On the horizontal axis, place the lower value of each interval. Label this axis with the type of data shown (Score, etc.)
Draw a bar extending from the lower value of each interval to the lower value of the next interval. The height of each bar should be equal to the frequency of its corresponding interval.
That's how it's done!
Answer:
Step-by-step explanation:
Stephan can run
3 miles in 15.75 minutes
1 miles in 15.75/3 minutes
1 miles in 5.25 minutes
Kelsha can run
5 miles in 226 minutes
1 miles in 226/5 minutes
1 miles in 45.2 minutes
Stephan can run faster, since 5.25 < 45.2
Find volume of each bill and each room
v=lwh
vbill=6.14*2.61*0.0043=0.06890922 in^3
must convert room dimientions to inches
25*12=300in
23*12=276in
15*12=180in
Vroom=300*276*180=14904000in^3
now 1 billion bills
move decimal place over 9 places to right
1 million bills takes about 68909220 in^2
how many rooms to fit them all?
vbillionbills/v1room=number of rooms needed=
68909220/14904000=4.623
round to 1 deicmal
4.6 rooms needed (actually, it would be 5 since you can't use the 0.4 room left over very efficiently)
answer is 4.6 rooms
Answer:
63
Step-by-step explanation:
Total groups: 21
number of students in each group: 3
total = 21 *3 =63
