The mean score for freshmen on an aptitude test at a certain college is 540, with astandard deviation of 50. assume the means to be measured to any degree ofaccuracy. what is the probability that two groups selected at random, consisting of32 and 50 students, respectively, will differ in their mean scores by (a) more than20 points

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
