Answer:
(2x²+6x-22) ft
Step-by-step explanation:
l = (x²+2x-16) ft
and w = (x+5) ft
the Perimeter =
2(x²+2x-16) +2(x+5)
= 2x²+4x-32+2x+10
= 2x²+6x-22
Answer:
option B.
About 16% of the books have fewer than 150 pages
Step-by-step explanation:
Since we are dealing with a normal distribution
68.27% of the values will fall in the range with the standard deviation
(180-30 , 180+30) = (150, 210)
Approximately 15.86% of the values will be higher than 210
and the rest 15.86% will be lower than 150
So the correct answer is option B.
About 16% of the books have fewer than 150 pages
Idk.. If you divide 488 by 3 you will have your answer.
Its easy math.
