EXPLANATION
The given functions are:
and
The following statements are true;
h(x) is the reflection of g(x) in the x-axis.
g(x) opens upwards while h(x) opens downwards
Both functions have their vertex and intercepts at the origin.
The x-axis is a tangent to both functions at x=0.
g(x) has a minimum point
h(x) has a maximum point.
Answer:
Mean = 497.5
Median = 379.0
First Quartile = 289
Third Quartile = 771.5
Step-by-step explanation:
Mean is used to measure the central tendency of data which represents the whole data in the best way. It can be found as the ratio of the sum of all the observations to the total number of observations.
⇒
⇒ Mean = 497.5
Median is the middle observation of given data. It can be found by following steps:
Arranging data in ascending or descending order.
Taking the average of middle two value if the total number of observation is even, and this average is our median.
or, if we odd number of observation then the most middle value is our median.
Here, number of observation is 11.
So the middle value is (11+1)÷2 = 6th term
⇒ Median = 379
The mode is the observation which has a high number of repetitions (frequency).
Here frequency of all observation is same. So, it is multi- modal data.
First Quartile is the middle value between Minimum value and Median of data after arranging data in ascending order.
First Quartile (Q₁) = 289
The third Quartile is the middle value between Median and Maximum Value of data after arranging data in ascending order.
Third Quartile (Q₃) = 771.5
