- Any quality, amount, or number that can be gauged or tallied qualifies as a variable. A data item is another name for a variable.
- A sample is a subset of units chosen to represent all the individuals in a population. Because just a portion of the population was counted, it is only a partial enumeration. To estimate the characteristics of the total population of interest, data from the sampled units is used.
- A statistic is a numerical representation of a sample, whereas a parameter is a numerical representation of the entire population.

Hello :
an equation is : y-5 = 0( x+7)...(the slope =0 '<span> horizontal line ' )</span> y=5
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 :)
Congruent since all angles are equivalent to each other.
