What is the missing step in the given proof?
a.
statement: m∠4 = m∠15
reason: substitution property of equality
b.
statement: m∠4 + m∠8 = 180°
reason: definition of supplementary angles
c.
statement: ∠7 and ∠8 are supplementary.
reason: linear pair theorem
d.
statement: m∠4 = m∠16
reason: transitive property of equality
e.
statement: ∠15 and ∠8 are supplementary.
reason: transitive property of equality

What is a possible solutions of the x> 3?

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
