Virty [35]

hi

-16t²+250 = 75

-16t² = 75 -250

-16t² = -175

  t² = -175 /-16

 t² = 175/16

Here there si two solutions :  t = \sqrt{175/16}   and  t =  - \sqrt{175/16}

However, as time cannot rewind,  we will  keep only positive solution

So t = \sqrt{175/16}

   

in seconds  it will be  :  3.3 seconds

The average age of instructors at a local college is 55, with a standard deviation of 6 years; the average salary is $37,000 wit
Lerok [7]
To solve for the coefficient of variation you will need this formula:
CV = (SD/X) x 100 
Where: CV = Coefficient of Variance
             X = Mean/average
             SD = Standard Deviation

To determine which one is more variable, just get the coefficient of both and compare.
                   AGE                                            SALARY
   
  CV = (6/55) x 100                             CV = (4,100/37,000) x 100
        = 10.90                                             = 11.08

Based on the results, salary is more variable because 10.90<11.08.
