y = -2(x-4)2-6
= -4(x-4) - 6
= -4x + 16 -6
y = 10- 4x
now if x is positive, x >= 0
then max value of y will be when x will nr minimum
so max y = 10- 4×0 = 10
so y = 10 at x =0 for x >=0
if x < 0 then
y will be increasing as x gets increase towards more negative. so max of y will be decided when x reaches to max negative.
Answer:
7/20
Step-by-step explanation:
<span>The first group is 5 - 9, the second group is 10 - 14 and the third group is 15 - 19. We now find the number of data within the interval 15 - 19. In the given frequency distribution, 17, 15, 18, 19, 19 and 16 are within the interval 15 - 19. Therefore, the frequency of the third group is 6.</span>
