There is a relationship between confidence interval and standard deviation:

Where

is the mean,

is standard deviation, and n is number of data points.
Every confidence interval has associated z value. This can be found online.
We need to find the standard deviation first:

When we do all the calculations we find that:

Now we can find confidence intervals:

We can see that as confidence interval increases so does the error margin. Z values accociated with each confidence intreval also get bigger as confidence interval increases.

All three angles on a triangle always equal 180°.
Example: 100°+40°+40°=180°
102+39=141°
180-141=39°
x = 39°
Answer:
Step 1: Simplify both sides of the equation.
−7f=12
Step 2: Divide both sides by -7.
−7f
−7
=
12
−7
f=
−12
7
Step-by-step explanation
sorry for the answer like this i couldnt find the fractions but the answer is f=-12/7 sorry :(
