First, arrange the numbers in order.
50, 55, 58, 60, 62, 64, 68, 70, 72, 76, 84, 92
the minimum (or lower-extreme) would be 50, since it is the lowest number.
the lower quartile would be 59, since 58 and 60 are the two middle numbers on the lower side, you would do 58+60 / 2.
the median would be 66, since 64 and 68 are the two middle numbers. you would do 64+68 / 2.
the upper quartile would be 74, since 72 and 76 are the two middle numbers on the upper side, you would do 72+76 / 2.
the maximum (or upper-extreme) would be 92 since it is the largest number.
to graph, put in your numbers at the bottom (i would probably count by twos). then plot your minimum, lower quartile, median, upper quartile, and maximum. next, draw a box around the lower quartile and upper quartile with the median inside the box. lastly, extend two lines from the left and right side of the box connecting to the minimum and maximum.
i hope this makes sense ! this is what goes through my head when i solve these kinds of problems lol
Answer:
Step-by-step explanation:
line given is x-y+1= 0
you can rewrite it in slope intercept y=mx+b where m is the slope, and b is the y-intercept where the line meets the y-axis
x-y+1 =0 subtract x and 1 from both sides of the equation
-y = -x-1 multiply both sides by -1
y = x+1 so the slope of this line is 1 and the y-intercept is 1
If you draw this line you can see that there are actually 2 lines that form 45° angles with y=x+1 and pass through (-1, 2), one is vertical x= -1 and one horizontal y =2
Answer:
The answer is A.
Step-by-step explanation:
I took the test!
All are correct except these 2:
The graph has one x-intercept:
No, the graph does not cut at the x-axis at all, there is no x-intercept.
The graph as a y-intercept at (5,0):
No, the y-intercept is at (0,5)
