The scores of high school seniors on the ACT college entrance examination in a recent year had a mean of 19.2 and a standard deviation of 5.1. The distribution of scores is not exactly Normal (ACT score is clearly not a continuous variable) but the Normal curve is a close approximation. (I will show an example in class.)
What is the approximate probability that a single student randomly chosen from all those taking the test scores 27 or higher?

The approximate probability is .

Valentino starts with a population of 1,500 amoebas that increases 35% in size every hour for a number of hours, h. the expression 1,500(1+0.35)h finds the number of amoebas after h hours. which statement about this expression is true? a. it is the initial population raised to the growth factor after h hours. b. it is the sum of the initial population and the percent increase. c. it is the sum of the initial population and the growth factor after h hours. d. it is the product of the initial population and the growth factor after h hours.

5. which description does not guarantee that a quadrilateral is a squar ajo is a parallelogram with perpendicular diagonals 0% has all sides congruent and all angles congruent o has all right angles and has all sides congruent 10% is both a rectangle and a rhombus 30%

Which graph has figures that can undergo a similarity transformation to justify that they are similar? (obviously not the third one)
