Answer:
the first one is a straight line
Answer:
20,480
Step-by-step explanation:
17 would round up to 20 cuz 5,6,7,8,9, round up and 1,2,3,4, round down easy
One way to do this is to try the different option to replace x. Let's start with 8. Two sides of the rectangle would be 8.
8*2=16
Now you have to take 16 from 40 to see what's left.
40-16=24
2(20-8)=2(12)=24
That means 8 is an option to use, but you still need to see if any of the other options work to find the greatest area.
9*2=18.......40-18=22.......2(20-9)=2(11)=22
9 would also work.
10*2=20.......40-20=20.......2(20-10)=2(10)=20
10 would work
11*2=22.......40-22=18.......2(20-11)=2(9)=18
So all of them would work. Now you just need to find the largest area, which is length x width.
x(20-x)
8(20-8)=8(12)=96
9(20-9)=9(11)=99
10(20-10)=10(10)=100
11(20-11)=11(9)=99
So if x is 10, It would make the largest area.
(Sorry for all the extra work. I never trust that all the answers would work for the perimeter)
Answer: Lower = 1 Median = 2 Upper = 4
Upper ≠ 1 so statement is false
<u>Step-by-step explanation:</u>
The Lower quartile (Q1) is the left side of the box.<em> I estimate it to be 1.</em>
The Median (Q2) is the line dividing the box.<em> I estimate it to be 2.</em>
The Upper quartile (Q3) is the right side of the box.<em> I estimate it to be 4.</em>
<em />
The upper quartile is the 75th percentile. It is not 1 so the statement is false.
V(x) = (2x - 3)/(5x + 4) The domain is all Real numbers except x = -4/5, because if x = -4/5 the denominator would be zero and you cannot divide by zero.{x | x ∈ R, x ≠ -4/5} w(x) = (5x + 4)/(2x - 3)similarly, x ≠ 3/2so, {x| x ∈ R, x ≠ 3/2}
