GMAT Prep : Practice Test 1 2024 with 100% correct answers

WHEN YOU SEE: -An Isocleles Triangle with a hypotenuse that doesn't have the √2 next to it -How do you do that quick equation ex: ISO triangle : Hypotenuse = 16 correct answers-Divide the hypotenuse by 2 and multiple by √2 . ex: 16 = 16/2 = 8*√2 = 8√2 When you see: -An abstract sequence question -such as... ex: if the terms of sequence t1,t2,t3,...tn, what is the value of n? 1. The sum of the n terms is 3,124 2. The average (arithmetic mean) of the n terms is 4 correct answers-Think about what the information they give you in the prompts and try to decode what they are asking for -They give you both the total sum and average -From here you will be able to put them together to find # over terms which would equal n When you see: -you are picking from 4 choices and making 2 picks -asking for probability for picking 1 specific pair ex: If two of the four expressions x+y, x+5y, x-y, and 5x-y are chosen at random, what is the probablity that their product will be the form of x²-(by)² correct answers-Set up probability formula -The bottom will be 4 slots and 2 picks (C:n-4,k-2) which will give you 6
