The IQR or interquartile range is the difference between Q1 and Q3, also know as the upper and lower quartiles.
Answer:
- The second graph, top right
Step-by-step explanation:
#1, top left
- Has repeating x- values at x = -2, not a function
#2, top right
- No repeat, input or outputs, is a function
#3, bottom left
- Has repeating x- values at x = 0, not a function
#4, bottom right
- Has repeating x- values at x = -1, not a function
Answer:
The driver was traveling at approximately 68.2 miles per hour
Step-by-step explanation:
Recall that one km equals approximately 0.62 miles, therefore, in order to find the speed of the driver in miles per hour, we just need to convert the 110 km into miles.
if one km equals 0.62 miles, then 110 km will equal the product of 110 times 0.62 miles. That is:
110 * 0.62 = 68.2 miles
Then the speed will translate into :
110 km/h = 68.2 mi/h
Answer:
Option D.
Step-by-step explanation:
We need to find the solution to the system graphed below.
If a system of equation have 2 linear equation then the intersection point of both lines lines is the solution of the system of equations.
In the given graph two straight lines intersect each other at (-1,-1).
Point of intersection = (-1,-1)
So, by using the given graph we can conclude that the solution of given system of equations is (-1,-1).
Therefore, the correct option is D.
