Answer:
47.6m.
Step by step solution:
Perimeter of a triangle = base + 2 . length____(1)
Area of a triangle = 1/2 . base . diagonal
108 = 1/2 . base . 15
multiplying both sides by 2:
216 = 15 . base
dividing both sides by 15:
base = 14.4m
But the diagonal divides the triangle into two
right angle triangles each with the same length (hypotenuse),base and diagonal(height).
Taking one right angle triangle:
And using pythagoras theorem;
length² = base² + diagonal ²
length² = 7.2² + 15²
Note: Base of each right angle triangle is 7.2 which would sum up to be 14.4 the base of the full triangle.
length² = 276.84
taking the square root of both sides:
length = 16.6m
Putting the values of the base and length into equation (1).
Perimeter of the triangle = 14.4 + 2 . 16.6
Note: We are dealing with the whole triangle
now hence the base is 14.4m.
Perimeter of the triangle = 14.4 + 33.2 = 47.6m.
The mean absolute deviation is 30
The probability of randomly drawing a chip number that is smaller than 201 is 0.541
<h3>What is the probability of randomly drawing a chip number that is smaller than 201?</h3>
The given parameters are
Plastic chips = 1 to 370
This means that
Chips = 370
There are 200 sections that are smaller than 201
This means that the probability is
P = 200/370
Evaluate
P = 0.541
Hence, the probability of randomly drawing a chip number that is smaller than 201 is 0.541
