Step-by-step explanation:
the answer is x is equals to 2 or x is equal to -5 in the equation x square + 3x - 10 is equals to zero where after solving you get x square + 5 x - 2 x - 10 is equals to zero you factorise you get x (x + 5) - 2 (x + 5) is equal to zero then after solving x is equals to 2 or -5
<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>
