Answer:

11+2x= 52 , $20.50 equal one pass

Step-by-step explanation:52 is the total and $11 is included in that total. So you have part of your equation : 11 + something = 52. In order to find that " something " you have to set up a variable : 2x , 2 because that is the amount of passes bought and X because you don't know the cost of the passes yet. You now have your equation : 11+2x=52. Next you isolate the "2x" by subtracting eleven from itself and what you do to one side of the equation you have to do to the other, so you subtract 11 from 52 and are left with 41 . You then have the simplified equation : 2x=41 . Now you're going to isolate the variable by dividing 2x by 2 and doing the same to 41. You're then left with X= 20.50 , the cost of one ticket

Vilka [71]

Answer:

Program C allows students to earn a Mathematics degree (B.A. or B.S.) by combining courses in the Department of Mathematics with courses from one other department.  In most areas of specializations, mathematical and/or quantitative courses in other departments are part of the math degree program.  All Program C students take a minimum of five core math courses:  Calculus I, Calculus II, Calculus III, Introduction to Linear Algebra, and a proofs course, usually either Introduction to Abstract Algebra or Fundamental Properties of Spaces and Functions I.

Find the probability that the mean annual preciptiation will be between 32 and 34 inches. variable is normally distributed
liq [111]
Supposing, for the sake of illustration, that the mean is 31.2 and the std. dev. is 1.9.

This probability can be calculated by finding z-scores and their corresponding areas under the std. normal curve.  
                                                                     34 in - 31.2 in
The area under this curve to the left of z = -------------------- = 1.47 (for 34 in)
                                                                           1.9
                                                                      32 in - 31.2 in
and that to the left of 32 in   is               z = ---------------------- = 0.421
                                                                             1.9

Know how to use a table of z-scores to find these two areas?  If not, let me know and I'll go over that with you.


My TI-83 calculator provided the following result:

normalcdf(32, 34, 31.2, 1.9) = 0.267  (answer to this sample problem)
