I am not sure what the question is here. I can tell you how to find the percent of kids that developed influenza in that class. We can compare it to the 20% of students nationwide. There could many different questions that stem from the piece of information you gave.
To find the percent of kids that developed influenza in that class do 6÷15 which gives you
.4 and written as a percent would be 40%.
Please message me if you have any questions! Hope this helps!
Answer:
(2x+1) -(-x^2+3x)
Step-by-step explanation:
r(x) = –x² + 3x
s(x) = 2x + 1
find the difference of (s-r)(x)
(s- r)(x) = s(x) - r(x)
we are given with s(x) and r(x)
to find the difference we plug both functions
(s- r)(x) = s(x) - r(x)
distribute negative sign inside the parenthesis
(2x+1) -(-x^2+3x) is the way we find difference
Answer: 170
Step-by-step explanation:
Hemisphere volume formula
V = (2/3)πr3
(2/3)•(3.14)•(2.5)^3=32.7 (33)
Cylinder volume formula
V=πr^2h
(3.14)(2.5)^2(7)=137.4 (137)
137+33=170
