<h2>Answer:</h2>
The correct answer is: Option: A
A. 85, 78, 80, 108, 46, 66, 68, 82, 72, 68
<h2>Step-by-step explanation:</h2>It is given that:
The whisker ranges from 66 to 85.
The box ranges from 68 to 82 with the vertical bar inside the box at 75.
- Hence, the minimum value of the box plot is: 66
- Maximum value of box plot is: 85
Also,
- The first quartile or the lower quartile i.e.
is: 68
- The middle quartile or median i.e.
is: 75
- The upper quartile or third quartile i.e.
is: 82
Also, it is given that:
One dot mark above forty-six.
One dot mark above one hundred and eight.
A)
On arranging the data in increasing order after removing outliers 46 and 108 we have:
66 68 68 72 78 80 82 85
Hence, from this data we have:
Minimum value=66
maximum value=85
As all the values matches the value defined.
Hence, this option is correct.
B)
On arranging the data in increasing order after removing 46 and 108 we have:
66 68 68 70 70 80 82 85
Hence, from this data we have:
Minimum value=66
maximum value=85
As the value of .
Hence, this option is incorrect.
C)
On arranging the data in increasing order after removing 46 and 108 we have:
66 68 72 78 80 80 82 85
Hence, from this data we have:
Minimum value=66
maximum value=85
As the value of do not match.
Hence, this option is incorrect.
D)
On arranging the data in increasing order after removing 46 and 108 we have:
66 68 68 72 78 80 80 85
Hence, from this data we have:
Minimum value=66
maximum value=85
As the value of do not match.
Hence, this option is incorrect.
Answer:
a)
b) When t = 10, Q = 7.845.
Step-by-step explanation:
The value of a quantity after t years is given by the following formula:
In which is the initial quantity and r is the rate that it changes. If it increases, r is positive. If it decreases, r is negative.
a) Write a formula for Q as a function of t.
The initial value of a quantity Q (at year t = 0) is 112.8.
This means that .
The quantity is decreasing by 23.4% per year.
This means that
So
b) What is the value of Q when t = 10?
This is Q(10).
When t = 10, Q = 7.845.
