1) What is the mean of the data set:
The best plot is the dot plot. Sum the values of each dot and divide by the number of dots.
2) What is the median of the data set:
Use the box plot. The median is the value in the middle of the rectangle. That is 8.
3) What is the interquartile range:
Use the box plot. The interquartile range is the length of the rectangle. That is 10 - 6 = 4
4) How many members use the facility 10 days a month:
Use the box plot. The answer count how many dots are over the number 10. That is 2.
Answer:
y = 9x - 5
Step-by-step explanation:
The slope is already given, so we just need to find the y-intercept.
Plug in 9 for m, 1 for x, and 4 for y in the equation y = mx + b.
4 = 9(1) + b
b = -5
Now that we know the y-intercept, we can construct the equation of the line.
y = 9x - 5
Let the number be x.
The product of two and a number is less than twenty is 2x < 20
Step-by-step explanation:
Triangle X with vertices (−2, 4), (2, 4), and (−2, 2)
The solution is 
and 
Step-by-step explanation:
The expression is 
and 
Using substitution method we can solve the expression.
Let us substitute 
in
Expanding and simplifying the expression, we get,
Let us use the quadratic equation formula to solve this equation,
Thus, 
and 
Substituting y-values in the equation , we get the value of x.
For ⇒ 
For ⇒ 
Thus, the solution set is and
