Answer:
the number of sponges per package bought be 32.5
Step-by-step explanation:
Let us assume the number of sponges per package be x
So the number of packages he bought be x - 14
And, the overall he bought 51 sponges
So
the number of packages of sponges did roger buy is
x + x - 14 = 51
2x = 51 + 14
2x = 65
x = 32.5
So the number of sponges per package bought be 32.5
Answer: 0. 74
Step-by-step explanation: 31/42= 0.738095238095= 0.74
Standard deviation illustrates how the data elements of a dataset differ from the mean of the dataset.
The true statement is:
<em>D. Boxplot II likely has the data with the larger standard deviation because the boxplot appears to have a greater spread, which likely results in a larger standard deviation</em>
From the given boxplots, we have the following observation
<u>Boxplot 1</u>
<em>Minimum = 9</em>
<em>Maximum = 26</em>
<u>Boxplot II</u>
<em>Minimum = 4</em>
<em>Maximum = 25</em>
Calculate the range of both plots
So, we have:
The above shows that boxplot II has a greater range
Range is a measure of the spread of the dataset.
The higher the range, the higher the spread
This means that box II has a greater spread
Because box II has a greater spread, it will have a greater standard deviation.
Hence, (d) is correct
