Answer:
53
Step-by-step explanation:
1) Take the area of the rectangle from origin to Point B. We see that it is 8 * 11 = 88 units of area
2) We subtract all the triangles in the rectangle that are not covered by the shape.
So
- Triangle FAPoint(0,-8) area = 1/2 * 2 * 5 = 5
- Triangle FEPoint(0,-3) area = 1/2 * 3 * 4 = 6
- Rectangle P(0,0) P(0,-3) P(6,-3) P(6,0) area = 6 * 3 = 18
- Triangle DP(6,0)P(11,0) area = 1/2 * 5 * 3 = 7.5
Take the area of the big imaginary rectangle and subtract the area of all the smaller triangles and the smaller rectangle
88 - 5 - 6 - 7.5 - 18 = 51.5
Done!
Answer:
at least 5
Step-by-step explanation:
<u><em>If the question was similar to the one given below </em></u>
A researcher plans to identify each participant in a certain medical experiment with a code consisting of either a single letter or a pair of distinct letters written in alphabetical order. What is the least number of letters that can be used if there are 12 participants, and each participant is to receive a different code?
<em><u>The answer would be as follows</u></em>
If we use 3 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
4C2= 6 ways to use these letters and the comma
If we use 4 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
5C2= 10 ways to use these letters and the comma
If we use 5 letters or any distinct letter as a comma such that 2 are in alphabetical order then we would get
6C2= 15 ways to use these letters and the comma
We need the least number of the alphabets to assign codes to 12 participants.
So the least number of alphabets is 5 because it can give codes to at least to 12 people .
Pair of alphabets + distinct letter ≥ 12
5 + 1 ≥ 12
6c2 ≥ 12
15 ≥ 12
Answer:
1/27
Step-by-step explanation:
The outcomes when rolling a die are 1,2,3,4,5,6
getting less than 3 = 1,2
P( less than 3) = outcomes of less than 3 / total
= 2/6 = 1/3
Since the events are independent we can multiply the probabilities
P( less than 3, less than 3, less than 3) = 1/3 * 1/3*1/3 = 1/27
Answer:
it means it is less than one
Answer:
t=20n
Step-by-step explanation:
The answer would be t=20n or something similar because 20n stands for $20 per lawn, which equals t, the total.
