Use the GCF of the terms to write the expression as the product of two factors with integer coefficients.
-2x3 - 4x2 + 4x
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.
If you're doing probabilities, there is a 1:6 chance on both (im guessing dont trust me i did probabilities a long time ago)
x + 17 ≥ -3
Isolate the x. Subtract 17 from both sides
x + 17 (-17) ≥ - 3 (-17)
x ≥ -3 - 17
x ≥ -20
----------------------------------------------------------------------------------------------------------------
x ≥ -20 is your answer
----------------------------------------------------------------------------------------------------------------
hope this helps
