Answer:
The graph in the attached figure
Step-by-step explanation:
Graph the solution of the inequality
we know that
The solution is the interval ---> (-∞,-4]
All real numbers less than or equal to -4
In a number line the solution is the shaded area at left of t=-4 (closed circle, because the number -4 is included in the solution))

Answer:
Second class have higher marks and greater spread.
Step-by-step explanation:
First box plot represents class first. From the first box plot, we get
Second box plot represents class second. From the second box plot, we get
First class has greater minimum value, first quartile of both classes are same, second class has greater median, first class has greater third quartile and first class has greater maximum value. It means second class have higher marks but class first have less variation.
Second class has greater range and greater inter quartile range. It means data of second class has greater spread.
Therefore, second class have higher marks and greater spread.
Answer:
The inverse function is to calculate the number of rides; given the amount paid
Step-by-step explanation:
Given
per ride
Required
Explain the inverse function
First, we calculate the function
Let x represents the number of rides
So:
For the inverse function, we have:
Swap x and y
Make 3y the subject
Make y the subject
Replace y with the inverse function
The above is to calculate the number of rides; given the amount paid
