The number of cases of a new disease can be modeled by the quadratic regression equation y = -2x^2 + 36x + 6, where x represents
the year.

Answer:
mean = 78.4
median = 77.5
mode = 75
This is Right - skewed (positive skewness) distribution
Step-by-step explanation:
<u>Mean:-</u>
The mean (average) is found by adding all of the numbers together and dividing by the number of items and it is denoted by x⁻
mean =
mean (x⁻ ) = 78.4
The mean of the given data = 78.4
<u>Median:</u>
The median is found by ordering the set from lowest to highest and finding the exact middle.
64 ,75, 80, 98
The middle term of the given data set =
<u>Mode :</u>
The mode is the most common repeated number in a data set.
64 ,75, 75, 80, 98
in data the most common number = 75
<u>Conclusion</u>:-
mean = 78.4
median = 77.5
mode = 75
This is Right - skewed (positive skewness) distribution
Answer:
Step-by-step explanation:
The Slope-intercept form of the equation of the line is:
m: is the slope.
b: the intersection of the line with the y-axis.
The equation of the line has:
If both lines are parallel, then their slopes are equal. So the slope of the other line is:
To find "b", substitute the given point and the slope into and solve for "b":
Then the equation of this line is:
