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
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.

Answer:
Possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
Step-by-step explanation:
Let the length of the silk fiber = x yards.
Let the number of silk fibres = a.
It is given that the silk fibers between 3 to 10 yards are combined to form a silk thread of 300 yards.
So, we get the equation,
, where
i.e. ,
So, the possible values of 'a' are 3, 4, 5, 6 an 10.
Thus, the possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.
