Two parallel lines are crossed by a transversal.
2 answers:
<u>Part a) What is the value of a?</u>
we know that
m∠a= -------> by corresponding angles
therefore
<u>the answer part a) is </u>
m∠a=
<u>Part b) What is the value of h?</u>
we know that
m∠h+ ---> by consecutive interior angles (supplementary angles)
m∠h=
m∠h=
therefore
<u>the answer part b) is</u>
m∠h=
<u>Part c) What is the value of b?</u>
we know that
m∠b= -------> by alternate interior angles
therefore
<u>the answer part c) is </u>
m∠b=

Answer:
Step-by-step explanation:
p = .3
n = 150
p(bar ) = 1 - p = .7
=.037
b )
P ( .2 <p<.4 ) = P [ (.2 - .3) / .037 < z < ( .4 - .3 ) / .037 ]
= P [ (-2.7 < z < +2.7 ]
= .9965-.0035
= .993
c )
P ( .25 <p<.35 ) = P [ (.25 - .3) / .037 < z < ( .35 - .3 ) / .037 ]
= P [ (-1.35 < z < +1.35 ]
= .9115 - .0885
= .823
