Identify the range using the box and whisker plot attached.
Harrizon [31]

Answer:

94 - 82 = 12

Step-by-step explanation:

Ok! Let's try and understand tye concept.

In a box and whisker plot, every vertical line in the box has a unique meaning. There are usually five vertical lines.

1st : LOWEST VALUE

2nd : LOWER QUARTILE

3rd: MEDIAN-

The Middle line is the MEDIAN. What it means is, the exact point where the vertical line intersects with the calibrated horizontal line, that point indicates the MEDIAN

4th: UPPER QUARTILE

5th : HIGHEST VALUE.

THE RANGE is calculated by subtracting the lowest value from the highest value.

That is: from the whisker point on the question-

HIGHEST VALUE = 94

LOWEST VALUE = 82

RANGE = 94 - 82 = 12

The attendence at a water park varies directly as the temperature and invesely as the number of days of rain during the month. I
Margarita [4]
Let A be attendance, t the temperature and n the number of days. Then,
A\alpha\frac{t}{n}
A=k\frac{t}{n}
Where k is a constant of proportionality;
If A=3200, T=88 and n=8, then k,
3200=\frac{88k}{8}
3200=11k
k=\frac{3200}{11}
Rewriting the equation and replacing the value of k,
A=\frac{3200t}{11n}
When t=92 and n=12
The A= \frac{3200*92}{11*12}
A=\frac{294400}{132}
A= 2231
