in a sample of 159,949 first year college students, the national survey of student engagement reported that 39% participated in community service or volunteer work.find the margin of error for 99% confidence. ...idk what formula to use.
Solve the system Y=3x-2 6x-2y=30
Solve the system X=2y+3 3x+4y=59
thanks. so how would u see if f is undefined? how do you get f from f'?
The derivative of a function f is f'(x) = x^2 - 8/x: Then at x = 2, f has A. an infection point B. a relative maximum C. a vertical tangent D. a discontinuity E. a relative minimum how do you test for all of these?
thanks! i forgot to add the 4 to the .5xy
A display case is in the shape of a rectangular box with a square base. Suppose the volume is 21 cubic ft and it costs $1 per square ft. to build the glass top and $0.50 per sq. ft. to build the sides and base. If x is the length of one side of the base, what value should x ha...
Find an equation for the tangent line to the curve x2y + xy3 = 2 at the point (1, 1).
oh sorry i see now. thanks!
x is suppose to be the number of trees planted per acre,
