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.
Lateral Area = PI * radius * slant height
Lateral Area = 3.14159 * 1.5 * 5

Answer:
The probability is 
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation is 
The sample size is n = 25
The combined resistance is 
Generally the sample mean is mathematically represented as
=> 
=> 
Generally the standard error of the mean is mathematically represented as
=> 
=> 
Generally the probability that a random sample of 25 of these resistors will have a combined resistance of less than 1010 ohms is mathematically represented as
From the z table the area under the normal curve to the left corresponding to 1 is
First divide 32 by 8
32/8
=4
