Let the difference between consecutive terms be D. If the middle term is 30, then the term before it is 30-D, and the term after it is 30+D. So the sum of these three terms would be (30-D) + 30 + (30+D) = 3*30.
Extending this sum to include all 11 terms centered around 30, we see that any addition of D is canceled by a balanced subtraction, leaving you with 11 copies of 30. So the value of the sum is 11*30 = 330.
Answer:
The average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).
Step-by-step explanation:
The service rate was given as $11, $84, $94 and $103.
The average service rate = 
= 
= 
= 73
Their average service rate is $73.
But comparing the average service rate to their given service rates, the average service rate ($73) is far greater than the least service rate ($11), and far less than the highest service rate ($103).
It means that when both sides of an equation have the same number subtracted from them the remaining expressions are equal. ( ......Hope that I helped you...... )
I believe that the answer is 4.4
Answer:
Option (4)
Step-by-step explanation:
m(∠PZR) = 
Radius of the circle = 8
Since, length of an arc = 
Here, θ = Central angle in radians
From the given formula,
m(arc PR) = 
= 
= 
Therefore, Option (4) will be the correct option.
