Answer:
A turning point is the highest or lowest point on a quadratic graph.
Step-by-step explanation:
A quadratic graph looks something like the graph below.
The equation of a quadratic graph would normally look like
+/- ax^2 + bx + c
An example might be -16x^2 + 5x + 4
Note the negative symbol in front of the 16. The negative means that the graph will be facing downwards, or that the turning point is the highest point. A positive graph will mean that the graph is facing upwards, or that the turning point is the lowest point.
Essentially, it is the location where a graph has its lowest or highest point and where the y-values (can include x-values in horizontal quadratics) "turn" to the direction they originated.
Answer:
x = 15
m∠1 = 45°
Step-by-step explanation:
2x + 15 + 135 = 180
2x = 180 - 15 - 135
2x = 30
x = 30/2
x = 15
180 - 135 = 45°
Answer:
<h3>The option b) is correct</h3><h3>The width of a confidence interval for one population proportion would decrease, increase, or remain the same as a result is <u>
Increase the value of the sample mean (0.5 point) </u></h3>
Step-by-step explanation:
Given that the width of a confidence interval for one population proportion would decrease, increase, or remains the same.
<h3>
To find the result for the given data :</h3>
By definition we have that "the width for the confidence interval decreases as the sample size increases". The width of the confidence interval increases as same as the standard deviation also increases. The width increases as the confidence level increases between (0.5 towards 0.99999 - stronger).
The width of a confidence interval is affected by 3 measures. they are the value of the multiplier t* , the standard deviation s of the original data, and the sample size of n .
<h3>Therefore the width of a confidence interval for one population proportion would decrease, increase, or remain the same as a result is <u>
Increase the value of the sample mean (0.5 point) </u></h3><h3>Therefore the option b) is correct</h3>
Two planes intersect at one line.
Take two sides of a cube. The sides of the cube meet at one edge. The sides are planes, while the edge is a line.
