The answer is Group 3 it literally gives the answer to you at the top and I just took the quiz myself.
The 2nd dot plot in the attachment represents the dot plot that has the same sample mean as the population mean
<h3>How to create the dot plot?</h3>
The dot plot that completes the question is added as an attachment.
Start by calculating the mean of the data plot using:
Substitute the values on the dot plot
This means that the population mean of the dot plot is 7
Next, we create another dot plot that has the same mean as 7.
There are no direct rules to this, so we make use of the trial by error method.
After several attempts, we have the following frequency table:
<u>Data point Frequency</u>
2 1
3 2
4 0
5 4
6 5
7 2
8 5
9 0
10 2
12 3
The mean of the frequency table is:
Evaluate
Evaluate the quotient
This means that the sample mean is 7 (same as the population mean)
Lastly, we represent the frequency table using a dot plot (the 2nd dot plot in the attachment)

Answer:2,910
Step-by-step explanation:
Answer:
6042915 balls.
Step-by-step explanation:
Volume of a ping pong ball is;
V = (4/3)πr³
diameter of ping pong ball is given 4cm = 0.04 m
Radius; r = 0.04/2 = 0.02 m
V = (4/3)π(0.02³)
V = 0.00003351032 m³
Room is 9.5 meters long, 7.5 meters wide, and 3 meters high.
Volume; V = 9 × 7.5 × 3 = 202.5 m³
Number of ping pong balls that will fit into the room = volume of room/volume of ping pong balls = 202.5/0.00003351032 = 6042914.540956151
Approximately 6042915 balls.
Answer:
24 cm²
Step-by-step explanation:
diagonals
d1 = 6 cm, d2 = 8 cm
Area of Rhombus
= 1/2 * d1 * d2
= 1/2 * 6 * 8
= 24 cm²
