Therefore
Hello!
This is a problem about relating circle theorems to line lengths.
We can first see that both line segment MK and CM are secants within the circle that come from a common point K.
This means that the Intersecting Secant Theorem applies here.
The Intersecting Secant Theorem states that if two secants are formed from a common point outside the circle, the length of each secant multiplied by the length of its corresponding external secant are equivalent.
We can set up the following equation.
Using this value, we can find the length of line segment MK.
Hope this helps!
Answer:
The correct options are:
- Four families said they ate out twice the previous week.
- One family said they ate out 5 times the previous week.
- The median best represents the data set.
Step-by-step explanation:
We are given a data set as:
4, 2, 2, 0, 1, 6, 3, 2, 5, 1, 2, 4, 0, 1
On arranging this data set in the frequency table we get:
Number of times they went for dinner Number of families
0 2
1 3
2 4
3 1
4 2
5 1
6 1
- Hence, the range of the number line is between 0 to 6.
- Also there are 4 dots above 2.
Hence, Four families said they ate out twice the previous week.
- Also there is one dot above 5.
Hence, One family said they ate out 5 times the previous week.
- The data set is not symmetrical since the median is 2 and the data points to the left and to the right do not have symmetry.
Hence, the data set is not symmetrical.
- Also we know that the median of the data is the central tendency of the data and always best represents the data.
Hence, The median best represents the data set.
