Since there are 4 numbers greater than 2 you can say that you have a 4 out of 6 chance
Process average or mean
is computed by dividing the total of the measurements made on the process by the number of measurements used to compute the total approximates. For example a coach wants to know if football players
who warm up before a game will score more points than those who don't warm up.
He will break the team up into two groups and make sure each player gets equal
time on the field. He will then count how many points each player makes during
the game. After counting them, add the scores of the group that he divided and
then divided it by the number of player in that group to get an average score
on teams that warm up or do not warm up before the game.
You are not going to be able to find a numerical value of this triangle because you do not know the type of triangle or the other side length. You can represent the perimeter using algebra though.
To find the perimeter you add the lengths of all 3 sides.
To show this as an algebraic expression, you would put 1 dm + 3 dm + x.
This will simplify to x + 4 dm, where x is the length of the missing side (in decimeter).
Given:
A square base pyramid with base length 6 cm and the slant height is 4 cm.
To find:
The lateral surface area of the given square pyramid.
Solution:
The lateral surface area of the given square pyramid is equal to the areas of 4 congruent triangles with base 6 cm and height 4 cm.
Area of a triangle is:
So, the area of one triangle or one side of the given pyramid is:
Now, the lateral surface area of the given square pyramid is 4 times the area of one triangle.
Therefore, the lateral surface area of the given square pyramid is 48 cm².
