Find the median, mode ,and range for 9.8 7.2 6.3 5.8 9.4 5.1 6.2 7.2

Median is 6.75

Mode is 7.2

Range is 4.7

Step-by-step explanation:

Given the set of data

9.8 7.2 6.3 5.8 9.4 5.1 6.2 7.2

First, we rearrange the data in an ascending or descending order.

Rearranging in an ascending order, that is from the smallest to the biggest number, we have:

5.1, 5.8, 6.2, 6.3, 7.2, 7.2, 9.4, 9.8

- The median is the middle number (If there is an odd number of data), or the average of the two middle number (If we have an even number of data).

In this case there are 8 numbers (even), and 6.3 and 7.2 are the middle numbers, so the median is

M = (6.3 + 7.2)/2

= 13.5/2

= 6.75

- The mode is the number that occurs the most times, 7.2 occurs twice, which is more times than any other number, so the mode is 7.2

- Range is the absolute difference between the biggest and the smallest number.

Range = 9.8 - 5.1

= 4.7

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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.
