If m<13=m<15=m<7, what conclusions can you make about lines a, b, c, and d?
1 answer:
Answer:
option D
Lines a and b are parallel and lines c and d are parallel.
Step-by-step explanation:
Given in the question four lines a , b, c, d.
<h3>Prove one</h3>If two parallel lines (a,b) are cut by a transversal(d), then corresponding angles m<7 and m<15 are congruent.
They are know as corresponding angles.
Hence lines a and b are parallel.
<h3>Prove two</h3>If two parallel lines (c,d) are cut by a transversal(d), then corresponding angles m<13 and m<13 are congruent.
They are know as corresponding angles
Hence lines c and d are parallel

Answer:
0.71%
Step-by-step explanation:
Given that a normally distributed set of data has a mean of 102 and a standard deviation of 20.
Let X be the random variable
Then X is N(102, 20)
We can convert this into standard Z score by
We are to find the probability and after wards percentage of scores in the data set expected to be below a score of 151.
First let us find out probability using std normal table
P(X<151) =
We can convert this into percent as muliplying by 100
percent of scores in the data set expected to be below a score of 151.
=0.71%
