Dear math , you write a great column, and i hope you stay around for years to come. i run a small boarding school. we are going to begin using test scores to determine admissions eligibility. the scores for the test i have in mind are normally distributed with a mean of 300 and a standard deviation of 12.5. can you show me how to determine the cutoff score if we should use to only accept only applicants who score in the top 10% on the test? what cutoff score includes the top 15%? in advance. regards, the student selector

Drag and drop the answers into the boxes to complete this informal argument explaining how to derive the formula for the volume of a cone. since the volume of a cone is part of the volume of a cylinder with the same base and height, find the volume of a cylinder first. the base of a cylinder is a circle. the area of the base of a cylinder is , where r represents the radius. the volume of a cylinder can be described as slices of the base stacked upon each other. so, the volume of the cylinder can be found by multiplying the area of the circle by the height h of the cylinder. the volume of a cone is of the volume of a cylinder. therefore, the formula for the volume of a cone is 1/3 1/2 1/3πr^2h 1/2πr^2h πr^2h πr^2

Is each relation a function? if so, state whether it is one-to-one or many-to-one. 3. (-4,7), (-3,5), (1,4), (3,-8), (5,-11) 4. (-4,8), (-2,4), (0,1), (2,4), (4,8) 5. (-2, 1), (-2,3), (0,-3), (1,4), (3,1)

What are “like terms”? why can we only add like terms?
