For a Standard Normal Distribution
Serggg [28]
In your question where ask to find the Standard Normal Distribution of the following:

give probabilities for 0<Z<infinity. For these ranges, you can read directly, for example, P(Z<1.96)=0.975. So for #1, you read directly on the line 1.3 and column 0.03. For #2, we note that the distribution is symmetrical about Z=0, so P(Z<-2.33) is the same as P(Z>2.33) which again is the same as 1-P(Z<2.33) because we know that the area under a probability distribution function adds up to 1. For the remaining questions, work is similar to #2.

What is the solution of 3x + y = 9 and 3x − 5y = 15?
erma4kov [3.2K]

Answer:

Multiply the first equation by five to yield, 15x + 5y = 45. Add this equation to the second equation from the given,

                                      15x + 5y = 45

                            +         3x - 5y = 15

The answer would be 18x = 60. The value of x is 10/3. Therefore, the answer to this item is letter A.
