for 7
Yes it is right cuz 16 is the double of 8 and even the price if doubled up so the price is right
for 8
Apply the formula





the diameter is 14
Hope this helps :)
Answer:
10 + 10 i
so a the 1 one
Step-by-step explanation:
Answer: 0.1359
Step-by-step explanation:
mean = $400
Standard deviation = $50
Since the wages is normally distributed , the first thing is to find the z - score.
z = 
finding the z - value for 300 and 350 , we have
z =
z = 
2 = -2
also
z = 
z = 
z = -1
The next thing is to check the calculated value on z - table.
From z - table :
P (z
-2 ) = 0.0228
P ( z
) = 0.1587
combining the two
P ( -2
z
-1 ) = 0.1587 - 0.0228
P ( -2
z
-1 ) = 0.1359
Therefore , the the probability that a worker
selected at random makes between
$300 and $350 = 0.1359
360 - 120 - 150 = 90
Interior Angle 1 = 180 - 120 = 60°
Interior Angle 2 = 180 - 150 = 30°
Interior Angle 3 = 180 - 90 = 90°
