The Answer is A 1.2 :))))))))))))
Answer: No it isn’t
Step-by-step explanation:
If you multiply the 3 to the 4c - 1 to get 12c - 3
12c - 3 doesn’t equal 12c - 3c
Answer:
x=127°
Step-by-step explanation:
The sum of the interior angles of a polygon is given by:

For a 6- sided polygon, the sum of interior angles is


We add the interior angles and equate them to 720°
x+112°+133°+128°+100°+120°=720°
x+593=720
x=720-593
x=127°
Answer:
.7147
Step-by-step explanation:
Let P be the probability of 55 families having mean more than 17
P { (17-17.2)/ (2.5/√55) }
P(- 0.5933 )
= - .2765 [ From the z table ]
P be the probability of 55 families having mean less than 18
P { (18 -17.2)/ (2.5/√55) }
P( 2.3732 )
= .9912 [ From the z table ]
Probability of mean between 17 and 18
= .9912 - .2765
= .7147
Answer:

Step-by-step explanation:
You just have to subtract 1/3x on both sides of the equation to cancel the 1/3x on the left.
