Answer:

4. 48, 24, 12

21. A, B, B, C

Step-by-step explanation:

There are two different questions here. One where you get to make up an exponential function and write a table of values. The other is a statistics problem in which you compare 5-number summaries.

<h3>Exponential Function</h3>

For the function f(x) = a·b^x, the value of f(0) is 'a'. The given table shows a=96. The only requirement for choosing 'b' is that it not be 1. We can choose b=1/2, and our table will be ...

y = 96·(1/2)^x

$\begin{array}{c|cccc}x&0&1&2&3\\y&96&\boxed{48}&\boxed{24}&\boxed{12}\end{array}$

For each increase of x by 1 unit, the value of y is cut in half.

<h3>Statistics</h3>

The attachment shows you how to find the answers to the questions.

The median is the bar in the middle of the box. The values for the different teams are ...

A: 78
B: 86
C: 82

Team A has the lowest median; Team B has the highest median.

The interquartile range (IQR) is the length of the box. For the different teams, the values are ...

A: 88-74 = 14
B: 90-78 = 12
C: 86-70 = 16

Team B has the smallest IQR; Team C has the largest.

By selling a stool for rupees 67.50,a carpenter loses 10%.how much percent would he gain or lose by selling it for rupees 82.50.

valentina_108 [34]

Let the actual value of the stool be x.

So if the carpenter sells the stool x rupees he neither loses, now wins anything.

67.50 is the value x - 10% of x, that is:

67.50=x-0.1x
67.50=0.9x

x=67.50/0.9=75 (rupees) is the actual value of the stool.

Selling the stool for 82.50 rupees, the carpenter clearly would make a profit, say of y% of that actual value, that is y%*75.

So using the same method:

82.50=75+y%*75

y%*75=82.50-75=7.5

we can make the calculations, but clearly 7.5 is 10% of 75

Answer: 10% gain.
