Answer:
0.53 will not chosen
Step-by-step explanation:
Given weights:
0.58, 0.63, 0.65, 0.53, and 0.61.
Computation:
Mean weight X = [0.58+0.63+0.65+0.53+0.61] / 5
Mean weight X = [3] / 5
Mean weight X = 0.60
Acceptable weight = l x-X l < 0.06
l x-0.60 l < 0.06
So solving inequality
0.54 < x < 0.66
So, 0.53 will not chosen.

y=-1
Answer:
81
Step-by-step explanation:
(9x - 4)(9x + 4) = ax² - b
81x² - 36x + 36x - 16
= 81x² - 16
=> a = 81
