The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:
Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:
From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%
Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism

The answer is C. (1,-3)
Answer:
12. b/y = c/b = ~ Polygon Similarity Postulate
13. b^2 = cy ~ Cross Multiply and Simplify
14. a^2 + b^2 = cx +cy ~ Addition Property of Equality
15. (CB)^2 + (CA)^2 = (AB)(DB + BA) ~ Distributive Property
16. x + y = c ~ Segment Addition Postulate
17. a^2 + b^2 = c^2 ~ Substitution Property
