This is one of those statistical follow-up questions and had to look for the options. Since the department of quality assurance is assessing the durability of the chairs being produced, the population that they are testing for quality is ALL THE CHAIRS THEY PRODUCED. Hope this helps.
You would do 300• 31/100 to get 90. I’m pretty sure that’s right
Answer:
(-infinity, 4]
Step-by-step explanation:
The range is the possible y values
The smallest that (x+3)^2 can be is zero
f(x) = 4 − 2(x + 3)^2
f(x) = 4 -2(0) = 4
This is the maximum value
As the square term gets bigger we are subtracting a larger amount and it will get more negative
Let x = infinity, x+3 = infinity and infinity ^2 = infinity and 2* infinity = infinity
f(x) = 4 - infinity
= -infinity
The range is -infinity to 4
