The surface area of the prism is given by:
Area=2(x*2x)+2(x(x+3))+2(2x(x+3))
=4x^2+2x^2+6x+4x^2+12x
=10x^2+18x sq. units
The volume will be given by:
V=length*width*height
=2x*x*(x+3)
=2x^3+6x^2 cubic units
Answer:
Actual mean: 223 pages
Predicted mean / estimate: 225 pages
Explanation below
Step-by-step explanation:
Mean = total amount ÷ # of numbers
155 + 214 + 312 + 198 + 200 + 170 + 250 + 260 + 215 + 256
Add
2,230
# of numbers = 10
2,230 ÷ 10 = 223
The exact mean is 223
If I were to predict the mean, I would say that a good estimation would be around 225, because I see that the highest number in the data set is 312, and the lowest is 155. If 312 is rounded down to 300, and 155 is rounded down to 150, the number exactly in the middle of 300 and 150 is 225.
Actual mean: 223 pages
Predicted mean: 225 pages
Hope this helps :)

Answer:
394 m
Step-by-step explanation:
From the solution diagram attached ;
The distance between boat and base of hill is represented as d ;
Using the trigonometric relation :
Tan θ = opposite / Adjacent
Tan 13 = 91 / d
Tan 13 * d = 91
d = 91 / Tan(13)
d = 394.16 m
d = 394 m (nearest meter)
