Answer:
The 95% confidence interval for the population proportion is (0.778, 0.884).
Step-by-step explanation:
We have to calculate a 95% confidence interval for the proportion.
The sample proportion is p=0.831.
The standard error of the proportion is:
The critical z-value for a 95% confidence interval is z=1.96.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 95% confidence interval for the population proportion is (0.778, 0.884).
Hi there! The answer is C.
We can see a reflection across the x-axis. The x-axis in this figure is an axis of symmetry. When we would measure the distance from a certain point in both of the triangles (the same point in the two triangles), this distance would be the same. Therefore this figure is reflected across the x-axis.
Answer:
do you have a picture of the graph?
Answer:
x=30
Explanation:
The sum of the exterior angles of a quadrilateral is always equal to 360 degrees. Knowing this, we can write the following equation:
5x+5x+x+x=360
12x=360
Divide both sides by 12
12x/12=360/12
x=30
I hope this helps!
