Answer:
Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.
Step-by-step explanation:
From given scatter plot, we see that upper quartile of Mrs. Cai's class = 4
lower quartile of Mr. Roland’s class = 4
Both are equal so that means.
That means Mr. Roland’s class was more successful because his class’s lower quartile was the same as Mrs. Cai’s class’s upper quartile.
Hence last choice is correct.
Answer:
To find the average rate of change, we divide the change in the output value by the change in the input value. The Greek letter Δ (delta) signifies the change in a quantity; we read the ratio as “delta-y over delta-x” or “the change in y divided by the change in x”.
The first amount would be the original amount as the answer because you are adding and then subtracting the same number. If the increase was 150% then the answer would be 50% more because 150%-100%=50%.
Answer:
y = 4/7x - 4
Step-by-step explanation:
You first have to put it in y = mx + b form
So, we first subtract 4x from both sides: -7y = -4x + 28
Divide both sides by -7
y = 4/7x - 4
Now to graph you have to start at the starting point which is -4
So we start with our point on -4 then move up 4 times and 7 times to the left. Mark the points then draw your line!
