Answer:
the answer will be 28
Step-by-step explanation:
180-47-31=102
since vertical angles have the same value the top angles for both triangles will be 102 degrees
102+50=152
180-152=x
28=x
Answer: The margin of error is 0.041.
Step-by-step explanation:
Since we have given that
n = 1010
x = 515
So, it becomes
At 99% level of confidence ,
z = 2.58
So, Margin of error would be
Hence, the margin of error is 0.041.
Answer:I believe it's 30.
Step-by-step explanation: 12*5=60 For a triangle you divide by two when you find the product. So
60/2=30 .
Answer:
p - 4
Step-by-step explanation:
Prime number is a number that only has 2 factors, 1 and the number itself. Therefore, multiplying p by 2 or 7 means giving the number more than 2 factors, which would make the number no longer prime. Squaring the prime number itself does the same.
Let p = 7.
2p = 2*7 = 14 14 = 1*2*7*14
7p = 7*7 = 49 49 = 1*7*49
p - 4 = 7 - 4 = 3 3 = 1*3
p^2 = 7^2 = 49 49 = 1*7*49
Step-by-step explanation:
<AOF and <COD are vertical angles.
m<AOF = m<COD = 80°
Angle Addition Postulate m<BOF - m<AOF = m<AOB
m<AOB = 135° - 80° = 55°
