Answer:
ok so the answers are:
Step-by-step explanation:
1) x-10/x-8
2) x+7/x-4
3) x-9/x+1
4) x-3/x+3
1. Write as an algebraic equation:
12 + n ≤ 2n - 8
2. Solve for n.
12 + n - 12 ≤ 2n - 8 - 12
n ≤ 2n - 20
n - 2n ≤ 2n - 20 - 2n
-n ≤ -20
Multiply both sides by -1 (this means you must flip the inequality sign).
n ≥ 20
FINAL ANSWER: n ≥ 20
Hope this helps! Feel free to ask for clarification.
Answer:
Both the mean and median are greater for Plot A than for Plot B.
Step-by-step explanation:
Plot A data set is : 4,4,5,5,6,6,7,7,10
mean(Plot A) = 5.7
median(Plot A) = 5.5
Plot B data set is : 4,4,5,5,5,6,6,6,7
mean(Plot B) = 5.1
median(Plot B) = 5
Both the mean and median are greater for plot A than for plot B.
Answer:
7.06 x 10^(-7) ft 3
Step-by-step explanation:
We have the formula to calculate the volume of an octagonal Pyraamid as following:
<em>+) Volume of octagonal pyramid = 1/3 * Area of the base * Height</em>
As given, the base of the pyramid is an octagon with area equal to 15mm2
=> Area of the base = 15 mm2
The height of the pyramid is the length of the line segment which is perpendicular to the base - which is the red line.
=> Height = 4mm
So we have:
<em>Volume of octagonal pyramid = 1/3 * Area of the base * Height</em>
<em>= 1/3 * 15 * 4 = 20 mm3</em>
<em />
As: 1 mm3 = 3.53 x 10^(-8) ft 3
=> 20 mm3 = 7.06x10^(-7) ft 3
So the volume of the pyramid is : 7.06 x 10^(-7) ft 3
