If I have 2 blue marbles, 3 red marbles, and 5 yellow marbles, what is the probabilty of selecting 2 red marbles and 3 yellow marbles if I draw 5 times without replacement?
Is there a clear-cut formula for this scenario where there is no replacement?
This question was on the actual 2013 ACT, so the answer cannot be wrong, but I’m so confused. The answer says it’s K.
I tried with the case where m = 2 (like y=2x + 1) and n = 3 (like y=x^2+x+1) and when I multiplied the two functions together, I got y=2x^3+3x^2+3x+1. So a total of 4 terms. But according to K, m*n, so there was to be 6 terms in the multiplied function, not 4??
I have no idea why the answer is A. I can’t seem to find any evidence in the passage that supports this answer... Could anyone help please?
Assume that the gas giant planets and the non-gas-giant planets (terrestrial planets) in another solar system in our galaxy have spatial and size relationships the same as those of the gas-giant planets and the terrestrial planets in our solar system. Given this assumption, in the other solar system, an existing gas giant planet would most likely be:A) located at a greater distance from the star than would any of the terrestrial planets.B) located at a lesser distance from the star than would any of the terrestrial planets.C) the same diameter as the largest terrestrial planet.D) a lesser diameter than any of the terrestrial planets.2 AnswersMathematics3 months ago
Please help me with this question... The answer says it is J. It could not be wrong as it was produced by the makers of the official ACT test.
I get that the vertical asymptote is x=3, but I thought that there was supposed to be no horizontal asymptote because the degree of the numerator function is larger than the degree of the denominator function. I get that they said the horizontal asymptote is y=16, because it is the midline of the vertex of the the two graphs, but midline is not equal to horizontal asymptote??2 AnswersMathematics3 months ago
