Answer:
Median is 12
Step-by-step explanation:
9, 10, 4, 12, 15, 17, 18, 10, 12, 13
Sort the data
4, 9, 10, 10, 12, 12, 13, 15, 17, 18
Median position: (n+1)/2
(10+1)/2 = 5.5th value
Median:
(12+12)/2
24/2
12
Putting the numbers from smallest to largest
4,9, 10, 10, 12 12, 13, 15, 17, 18,
The median is the middle number
There are 10 numbers
The middle number is between the 12's, so it is 12
i hope this helps you....
Answer: <u>96</u> sq ft.
First, we will find the area of the rectangular sides. Since the triangle is an equilateral triangle, all the rectangles will be the same size.
A = L * W
A = (10 ft) * (3 ft)
A = 30 ft²
30 ft² * 3 = 90 ft²
Next, we will find the area of the two triangles.
A =
3 ft + 3 ft = 6 ft²
Lastly, we will add them together for the total surface area.
90 ft² + 6 ft² = 96 ft²
Triangles ABC and XYZ are similar, so the corresponding angle to A in XYZ triangle is angle X. We can actually find sin(X) very easily.
Because we know all sides and the right angle, we can use certain formula to find sin(X), like this:
sin(X) = opposite side / hypotenuse = 6/10 = 3/5
sin(X) = sin(A)
The correct answer is sin(A) = 3/5.
