A confidence interval is simply the range of estimates for an unknown parameter, which is defined as an interval with a lower bound and an upper bound.

<h3>What is a confidence interval?</h3>

Your information is incomplete as the data is not given. Therefore, an overview of the confidence interval will be given.

A 90% confidence interval means that the researcher is 90% confident that the values of the results will simply fall between the upper and lower limits if the procedure is repeated again.

You can find a confidence level for data by simply taking half of the size of the confidence interval, then multiplying it by the square root of the sample size, and then dividing by the sample standard deviation.

Finally, look up the resulting ​Z​ or ​t​ score in a table in order to find the level.

For which independent value do the equations generate the same dependent value? y1=6x-16 , y2=3x-10
Nikitich [7]
The question asks which x-value gives the same y-value for both equations, so if you need the ys to be equal, you can set both equations equal to each other, giving you 6x-16=3x-10. Now, solve for x. 6x-16=3x-10, subtract 3x and add 16, 3x=6, divide 3, x=2. Your answer is x=2.

If the perimeters of each shape are equal, which equation can be used to find the value of x?
Brums [2.3K]

Answer:

(x+2) + x + (x+4) = 2(1/2) + 2(x+3)

Step-by-step explanation:

They are equal to each other and the rectangle has 2x more perimeter

The triangle would be divided in half from that rectangle.

Sorry If this is confusing I am not very good at explaining things.
