Answer: (x-8)(x-4)
How I like to factor simple trinomials like this is to find what c can multiply to be the sum of b. Then substitute that into (x)(x). For example, -8 times -4 is 32, and -4-8 also equals -12. Substitute to get (x-8)(x-4).
You can also use factor fish (photo example attached)

Answer:
interval = [17.3948 , 20.6052]
Step-by-step explanation:
given,
random sample (n) = 45
average product lifespan = 19 years
standard deviation = 4 years
confidence interval of 99 % = ?
we know,
t* = qt(1.99/2 + 44 ) = qt(0.995,44)
t* = 2.692
so,
interval
interval = [19 - 1.6052 , 19 + 1.6052]
interval = [17.3948 , 20.6052]
Answer:
It would cost $24 to produce 6 widgets.
Step-by-step explanation:
If you turn the information into points, you can use those three points to find the parabolic function for the graph (it's y=(x squared over 2) -2x +18.) All you have to do then is find where 6 widgets lines up with the graph.
