Answer:
Vertically opposite angles.
Step-by-step explanation:
A line is a one-dimensional figure having no thickness and extends infinitely in both the directions.
Intersecting lines are the lines which intersect at one point.
Parallel lines which do not intersect at any point.
An angle is formed by two rays meeting at a common end point.
Vertically opposite angles are the angles formed opposite to one another at the intersection of two lines.
Vertically opposite angles are always equal.
Answer:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
In this problem, we have that
90% confidence level
44% with a margin of error of 2%
So:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Answer:
y= -x+4 if x<0
y= x+4 if x≥0
Step-by-step explanation:
When writing a piece-wise function, we simply look at the portion of the graph that covers the given domain and derive an equation.
When looking at the part of the graph when x<0, we can derive the equation:
y= -x+4.
For x-values greater than 0, we can get:
y= x+4.
Answer:
The best way to measure an angle is to use a protractor. To do this, you'll start by lining up one ray along the 0-degree line on the protractor. Then, line up the vertex with the midpoint of the protractor. Follow the second ray to determine the angle's measurement to the nearest degree.
