Based on a random sample of business managers, researchers identify a salary range starting at $68,400 and ending at $201,250. Assuming a normal population distribution, the lower value, $68,400, is 1.65 standard deviations below the mean salary and the upper value, $201,250, is 1.65 standard deviations above the mean salary. According to this information, approximately what percentage of all business managers have salaries greater than $201,250?

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

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.

positive

step-by-step explanation:

the quadrant is facing upwards

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
