Pythagorean theorem is the equation set up/formula for solving equations for right triangles. I’m sure your familiar with
a squared plus b squared equals c squared. ( a^+b^=c^ )
That’s the simplified version!
The more you start to learn about it like in Geometry and in collage, the more complex it gets. Such as...
Finding the hypotenuse on the triangle
Hypotenuse=c^ in the simplified equation. The hypotenuse is always the longer side of the right triangle. Then from there, since all right triangles have 90 degree angles, after finding the 90 degree angle on the triangle, across from the degree, is the leg that we would label O for opposite. Leaving us with one last leg which we would label adjacent
Answer:
The mean is 2.75.
The margin of error is 0.62.
Step-by-step explanation:
In this case, we know the 95% confidence interval, and we want to know the mean and the margin of error.
The mean can be calculated as the average between the upper limit and lower limit:

The margin of error is the difference between the upper (or lower limit) and the mean. It equals the product between the z-value and the standard deviation divided by the square of the sample size.
It can also be calculated as half the difference of the limits of the confidence interval.
We only have the limits of the confidence interval to calculate the margin of error:

Answer:
C
Step-by-step explanation:
Since the graph hits 0 at x = 0, your y intercept is 0.
The graph is decreasing which means you have a negative slope.
They gave you a coordinate so use it to find the slope.

That's your slope.
C is the correct answer.
