Answer:
90 degrees
Step-by-step explanation:
the square in the corner of ∠CGD means 90 degrees and the ∠AGB is parallel to ∠CGD which means they have the same measure
I hope this helps and if correct may I please have brainliest.

Answer:
Let X the random variable that represent the variable of interest of a population, and for this case we know the distribution for X is given by:
Where and
And for this case we select a sample size of n= 81. Since the distribution for X is normal then we know that the distribution for the sample mean is given by:
And the standard error of the mean would be:
4.1.5
Step-by-step explanation:
Previous concepts
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".
Solution to the problem

Hey there!
Your equation will be f(x) = (5x + 1) / 2. Now, you'll need to find the inverse.
In the equation, replace f(x) with y, then switch x and y. Now, solve for y in the new equation. What equals y will be your inverse equation.
f(x) = (5x + 1) / 2
x = (5y + 1) / 2
(x)*2 = (5y + 1 / 2)*2
2x = 5y + 1
–1 –1
(2x – 1) / 5 = (5y) / 5
(2x – 1) / 5 = y
Your inverse function is f–1(x) = (2x – 1) / 5. Now, just plug in 8 for x and solve for the answer.
f–1(x) = (2x – 1) / 5
f–1(8) = (2(8) – 1) / 5
f–1(8) = (16 – 1) / 5
f–1(8) = 15 / 5
f–1(8) = 3
Your final answer will be 3. Hope this helped you out! :-)
