Answer:



Step-by-step explanation:
Given


Solving (a): The mean
Mean is calculated as:

This gives:



Solving (b): The median
Sort the data in ascending order:


The median is:



The 8th item on the sorted dataset is 7; So:

Solving (c): The mode

Because it has a frequency of 3 (more than any other element of the dataset).
First we need to find Mia's speed (v) in km/min
v = distance travelled/ time
v = 3 km/20 minutes
v = 0.15 km /min
in order to convert the speed into mile/min, we need to use the conversion factor given in which for every kilometer, there is 0.6 miles.
v = 0.15 km/min *(0.6 miles/ km)
v =0.09 miles/min
therefore the speed in miles/min is 0.09 miles/min
Answer:
8
Step-by-step explanation:
Let x be the number of people
12.5x + 13 < 125
x < 8.96
Max number of x is 8
Answer:
MN = LK because of the definition of a 'parallelogram'.
Step-by-step explanation:
We are given a parallelogram KLMN.
We know that a 'parallelogram' is a quadrilateral which have two opposite sides parallel and equal in length.
Therefore, from parallelogram KLMN, we get,
MN║LK and ML║NK
MN = LK and ML = LK.
Hence, we that MN = LK because of the definition of a 'parallelogram'.
