Answer:
Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A
Step-by-step explanation:
We are given the following in the question:
Product A:
Number of people,

Number of people who received relief,

Proportion of people who received relief from product A =

Proportion of people who did not received relief from product A =

Product B:
Number of people,

Number of people who received relief,

Proportion of people who received relief from product B =

Proportion of people who did not received relief from product B =

Product B performed worse in the study because 86% failed to get relief with this product, whereas only 78% failed to get relief with Product A
H(x) = 4x² - 8x - 60
0 = 4x² - 8x - 60
0 = 4(x²) - 4(2x) - 4(15)
0 = 4(x² - 2x - 15)
4 4
0 = x² - 2x - 15
0 = x² - 5x + 3x - 15
0 = x(x) - x(5) + 3(x) - 3(5)
0 = x(x - 5) + 3(x - 5)
0 = (x + 3)(x - 5)
0 = x + 3 or 0 = x - 5
- 3 - 3 + 5 + 5
3 = x or 5 = x
Divide by 100
Hope this helps!
