The median will stay the same but the mean will increase
a) 470 is still the smallest number in the sequence, so it doesn't have any effect
b) Mean is the same thing as average. By increasing the number from 454 to 470, you're increasing the mean by a value of 16/8 or 2 because you have 8 terms and the total value increased by 16.
8n-4n = 4n
4n+ 2 = 4n
Subtract 4n from both sides
2= 0

Isn't there no resistance between a light bulb that uses 15 watts of power when it is placed across a 15-volt battery?
Answer:
At x = 4 ⇒ g(x) = f(2)
Step-by-step explanation:
* In the functions f(x) = 3x - 1 and g(x) = 2x - 3, the domain is
the values of x and the range is the values of y
∵ g(x) = f(2)
* Then you will use the range of f(x) at x = 2 to find the domain of g(x)
∵ The domain of f(x) = 2
∵ f(x) = 3x - 1
∴ f(2) = 3(2) - 1 = 6 - 1 = 5
* The range of f(x) = 5
∵ f(2) = g(x)
∴ 5 = g(x)
∵ g(x) = 2x - 3
∴ 2x - 3 = 5 ⇒ add 3 to both sides
∴ 2x = 8 ⇒ divide both sides by 2
∴ x = 4
* At x = 4 ⇒ g(x) = f(2)
66+10 would equal 77. 77 subtracted by 4 equals73 73 squared equals 5329. 5329 divided by 6 is 888.166667
