Answer:
72 units
Step-by-step explanation:
A circle has a circumference of 452.16
The formula for circumference of circle =
Where r is the radius of circle
The approximate value of pi = 3.14
Given circumference C= 452.16
Divide both sides by 6.28
r = 72
So radius of the circle 72 units
Answer: The required probability is 0.004.
Step-by-step explanation:
Since we have given that
Number of pieces = 50
Number of defective pieces = 5
So, we need to draw 2 defective pieces.
So, the probability of drawing 2 defective pieces one after the other on the first and second samples would be
Hence, the required probability is 0.004.
Answer:
ii. Yes, a solution always exists.
iii. There is only one congruent solution to the problem.
Step-by-step explanation:
Two or more lines are said to be congruent is they have the same length. These lines could be at certain angles to each other, which can be constructed to produce a triangle.
Given line segments, constructing a triangle with sides congruent to the line would produce only one triangle.
See the attachment for an example of the construction.
