Answer:
3 bunches
Step-by-step explanation:
We are given that Alice is making balloon bunches from 6 red balloons and 15 blue balloons.
She wants the same number of red balloons and the same number of blue balloons in each bunch.
We have to find the greatest number of balloon bunches that Alice can making from all the balloons.
We will find the HCF of 6 and 15
Common factor of 6 and 15 is 3.
Hence, HCF of 6 and 15=3
Therefore, Alice makes 3 bunches with 2 red balloons and 5 blue balloons.

Find the length of one side.
V = s^3
s = cube root of V
V = 729
s = cube root 729
s = 9
Put this into your calculator as 729^0.333333333
It should bring back 9 or 8.999999 something which means 9.
Net
The net is shown below. You will have to do the labeling. But I can tell you what you should label each face as?
Area of one face = s^2
s = 9
Area of one face = 9*9
Area of one face = 81
So when you draw this, each face should be labeled with 81.
It should have it's units (ft^2) if your marker is picky.
Part C
There are 6 sides.
1 side has an area of 81 ft^2
6 sides have an area of 6*81 = 486 ft^2
Using it's concept, the standard deviation for the given data-set is of 8.22.
<h3>What are the mean and the standard deviation of a data-set?</h3>- The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
- The standard deviation of a data-set is given by the square root of the <u>sum of the differences squared between each observation and the mean, divided by the number of values</u>.
The mean for this problem is:
M = (17 + 26 + 28 + 9 + 30 + 29 + 6 + 21 + 23)/9 = 21
Hence the standard deviation is:
