two lines intersect and one of the angles formed has a measure of 67, which of the following statements are true? explain your answers.*
more than one answer may be correct; select all correct answers.
vertical angles are congruent; therefore another angle must equal 67°.
the lines form linear pairs.
the lines form complementary angles.
one of the angles formed measures 23
two of the angles formed measure 113
two of the angles formed will have a sum of 180°
none of the above.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

it would be 3 ÷by 6 because the number on each side

add them

step-by-step explanation:

idk you did not give the options or numbers so you cant solve it

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
