Assume that scores on a bone mineral density test are normally distributed with a mean of 0 and a standard deviation of 1.a. Find the z-score that separate the lowest 9% of scores from the highest 91%.b. For a randomly selected subject, find the probability of a score greater than -2.93.c. For a randomly selected subject, find the probability of a score between 0.87 and 1.78.

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.

Complete the conditional statement. if a + 2 < b + 3, then a < b b < a a – b < 1 a < b + 1

Right ∆abc has coordinates a(-7, 3), b( -7, 10), and c(-1, 3). the triangle is reflected over the x - axis and then reflected again over the y - axis to create ∆a'b'c'. which are the coordinates of vertex a'?
