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
Answer:
4π mi²
Step-by-step explanation:
s = (∅/360) * πr²
s = (135/360) * π(4²)
s = (135/360)(16) * π
s = 4π mi²
(x+4), (y-1) because the figure is translated 4 units to the right and 1 down.
Answer:

increases and remained the same.
Step-by-step explanation:
I just took the test and got it correct.
1) use distributive property
3x - 6 + 5x + 4
