Below are some summary statistics from the score variable. Which of the following is true? min Q1 Median Q3 max mean sd missing
30 57 69.5 77 99 60.075 16.09361 200 0

a. the standard deviation estimate is not possible because score is a whole number
b. there is evidence that the distribution of Score is right-skewed
c. the minimum value of 30 would be identified as outlier in a box plot
d. there were more survey respondents who reported job satisfaction scores less than 66 than survey respondents reported job satisfaction scores greater than 69
e. none of the above are true

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

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.
