Use the following data set to complete the problems.
23, 26, 50, 39, 55, 64, 50, 20, 42, 35, 51, 42, 43, 56, 64, 48, 48, 57, 27, 37
1. List the data values in order from lowest to highest.
2. Find n, the number of data values.
3. Find the width for a frequency distribution with 5 classes of equal width.
4. Create a frequency distribution table.
5. Show that the frequencies in the table add up to the sample size.
6. Create a histogram.

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
