the volume of a gas varies inversely as the pressure upon it. if the volume of the gas is 160 cubic centimeters at a pressure of

marin [14]

It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:

V α 1/P

To change it to an equality, we introduce a proportionality constant, k. We do as follows:

V = k/P

So, to determine what is asked, we need to first calculate for the value of k.

V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280

Thus, at P = 87 cmHg
V = 17280 / 87
V = 198.62 m^3

Scores on the final in a statistics class are as follows.

IgorLugansk [536]

Answer:

Kindly check explanation

Step-by-step explanation:

Calculate the 25th, 50th, and 75th percentiles.

b. Calculate the interquartile range.

c. Construct a boxplot. Are there any outliers?

Reordered data:

25, 40, 52, 55, 60, 70, 70, 72, 74, 75, 75, 80, 80, 85, 85, 86, 87, 90, 92, 99

25 th percentile :

1/4 (n + 1)th, tetm

n = 20

1/4(21) = 5.25th term

(5 + 6) th term / 2

= 65

50th percentile :

1/2 (n + 1)th, tetm

n = 20

1/2(21) = 10.5th term

(10 + 11) th term / 2

= 75

75th percentile:

3/4 (n + 1)th, tetm

n = 20

3/4(21) = 15.75th term

(15 + 16) th term / 2

= 85.5

Interquartile range :

Q3 - Q1

75th percentile - 25th percentile

85.5 - 65

= 20.5

25 is an Outlier
