Answer:
The correct answer is a) Mean =13173.6; median is 12765 no mode ; The median is the best choice because it is not skewed by the high outlier.
Step-by-step explanation:
Step 1
Arrange the data starting from the smallest to the biggest value. The arranged values are listed here as 11850, 12700,12765,13075,15478.
Step 2
Read the median and determine the mode in this data set.
The median is the value in the center which is 12765. Since every value only appears once, there is no mode for this data set.
Step 3
Calculate the mean of this data set. The mean is calculated by adding up all the values and dividing by the number of distance data available. In this case the data has 5 values, we will divide by 5. This calculation is shown below,
The mean for the data set is 13173.6
Step 4
The best measure of central tendency for this data is the median because it is not skewed by the high outlier. The mean is bigger than 4 of the data points and is skewed by the biggest distance.

Answer:
q=6
Step-by-step explanation:
q/2 - -5 =8
q/2 = 8-5
q/2 = 3
we do cross multiplication
q=3×2
q=6
Answer:
The length of segment QM' = 6
Step-by-step explanation:
Given:
Q is the center of dilation
Pre-image (original image) = segment LM
New image = segment L'M'
The length of LQ = 4
The length of QM = 3
The length of LL' = 4
The original image was dilated with scale factor = 2
QM' = ?
To determine segment QM', first we would draw the diagram obtained from the given information.
Find attached the diagram
When a figure is dilated, we would have similar shape in thus cars similar triangles.
Segment L'M' = scale factor × length of LM
Let LM = x
L'M' = 2x
Using similar triangles theorem, ratio of their corresponding sides are equal.
QM/LM = QM'/L'M'
3/x = QM'/2x
6x = QM' × x
Q'M' = 6
The length of segment QM' = 6
