Two video games, star chasers and song hero, had the same average price over a 10-month period. during that time, the price of song hero showed greater variability. if song hero was priced between $35 and $49 during the 10-month period, which statement is most likely true about price of star chasers during that time?
the highest price and the lowest price of the game differ by more than $14.
the highest price and the lowest price of the game differ by less than $14.
the mean price was more than $42.
the mean price was less than $42.

The answer would be B. The highest price and the lowest price of the game differ by less than $14. Hope this helps!

B. The highest price and the lowest price of the game differ by less than $14.

Given is that the the price of Song Hero showed greater variability. This means their prices are more varied in range.

If Song Hero was priced between $35 and $49 during the 10-month period, This means the variability of Star chasers is less than

Since, $14 is Song Hero’s range, the range for Star chasers should be less.

Therefore, option B is correct.

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.

step-by-step explanation:

the true ones are a b and d
