Answer:
∠AOB = 139°
Step-by-step explanation:
The 2 angles form a straight angle and sum to 180°, that is
∠AOB + ∠BOC = 180 ← substitute values
8x + 51 + 6x - 25 = 180, that is
14x + 26 = 180 ( subtract 26 from both sides )
14x = 154 ( divide both sides by 14 )
x = 11
Hence
∠AOB = 8x + 51 = (8 × 11) + 51 = 88 + 51 = 139°
Answer:
-2+8n
Step-by-step explanation:
we can distribute the -2 inside the parentheses to find an equivalent expression.
-2(1-4n)
(-2)(1)+(-2)(-4n)
-2+8n
there's your answer!
Draw a perpendicular line at the 4.5 kg to connect it to the line labeled with pounds and you would see that the 4.5 kg would be at the 10 pound mark.
The answer is 10 pounds.

Answer: 
or 0.5826
Step-by-step explanation:
Given : The total number of teachers in at a college = 318
In sample of n= 115 teachers from this college, the number of teachers with doctorates : x=67
Then, the sample proportion of teachers at this college with doctorates
Since the sample proportion is the best estimate of the population proportion.
Therefore , the estimated the population proportion of teachers at this college with doctorates =
