Let the width = x
=>length = 2x-1
91= x(2x-1)=2x^2-x
2x^2-x-91=0
=(2x+13)(x-7)
=> x=-13/2=> no
=>x= 7 cm
Number of proper subsets = 2^number of elements- 1
= 2^n - 1
No of elements = 4
2^4-1 = 16-1 = 15
1. Area of triangle
1/2(10)(12)=60
There are two triangles, so multiply by 2
=120
2. Find area of the rectangles
This is an isosceles triangle, so the two rectangles are congruent
(2)(13)(3)=78
3. Find area of bottom rectangle
10(3)= 30
4. Add everything up
120+ 78 + 30= 228
Therefore the surface area of this prism is 228
I hope i helped :)
Answer: The mean is 4, median is 4, no mode, range is 4
Step-by-step explanation:
<u>mode</u> is adding all the numbers and subtracting by the total amount of whole numbers
<u>median</u> is putting the numbers in a line ex.( 2, 6, 4, 5, 3) and crossing out left to right until theres one number left
<u>mode</u> is which ever number is repeated the most
<u>range</u> is the biggest number subtracted by the smallest number
