Answer:

f(10x-8)=-20x+22

f(g(x))

possibly

g(-2x+6)=-20x+52

g(f(x))

If needing a different answer math-way can possibly help you as it helped me.

Which point is Not on a circle with a center of (0,0) and a radius of 10?
Burka [1]
It is A because the radius is 10 which means that if x=0 then y must equal 10. (0,5) would be inside of the circle. If this doesn't make sense graph the circle and the points and you'll see what I mean.

Determine the point estimate of the population proportion and the margin of error for the following confidence interval.Lower bo
Kamila [148]

Answer: The point estimate of the population proportion is . 485.​

The margin of error is 0.273.​

Step-by-step explanation:

Confidence interval for population proportion(p):

sample proportion ± Margin of error

Given:  Lower bound of confidence interval  = 0.212

Upper bound = 0.758

⇒sample proportion - Margin of error=0.212  (i)

sample proportion + Margin of error= 0.758  (ii)

Adding (i) and (ii) , we get

2(sample proportion) =0.970

⇒ sample proportion = 0.970÷2= 0.485

Since sample proportion is the point estimate of the population proportion.

So, the point estimate of the population proportion=  0.485

Now put sample proportion =0.485 in (ii), we get

0.485+ Margin of error= 0.758

⇒  Margin of error= 0.758 - 0.485 =0.273

i.e. The margin of error is 0.273.​

What is the answer to 2.2=z/57
NeTakaya
It would be 125.4 . Find this by isolation the variable on the right side by using the multiplication property of equality. Multiply both sides by 57 so it would leave you with (125.4 = z). Hope this helps! :)
