Determine whether the relationship between the circumfrance of a circle and its diameter is a direct variation. If so, identify
1 answer:
Answer:
The relationship between the circumference of a circle and its diameter represent a direct variation and the constant of proportionality is equal to the constant
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
where K is the constant of proportionality
In this problem we know that
The circumference of a circle is equal to
therefore
the relationship between the circumference of a circle and its diameter is a direct variation and the constant of proportionality is equal to the constant

Step-by-step explanation:
The expected value is the sum of the value of each outcome times the chance that it happens. In this case, there are two outcomes:
- Win $31 million
- Win $0
Then our expected value can be calculated as:
The number of muffin can yield is 18.
Step-by-step explanation:
Given:
The recipe needs cup chopped apple.
To find:
Umber of muffins when 1 cup chopped apple is given.
Solution:
1 ÷
= 1.5
1 cup apple is 1.5 times of
cup of apple
So, the number of muffins will be = 12 × 1.5
= 18
Thus 18 muffins can be yielded from a batch that contains 1 1/8 cups of chopped apple
