Suppose a normal distribution has a mean of nine and a standard deviation of 1.75. What is the z-score of x

Lines p and q intersect. find the value of b. show your work. cite any theorems you use.

Match each expression with its simplified form.

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
