Answer:
Adjust the compasses' width to the point Q. The compasses' width is now equal to the length of the line segment PQ.
Step-by-step explanation:
Start with a line segment PQ that we will copy. Mark a point R that will be one endpoint of the new line segment. Set the compasses' point on the point P of the line segment to be copied. Adjust the compasses' width to the point Q. The compasses' width is now equal to the length of the line segment PQ.
we know that
Vertical angles are congruent angles
that means
substitute the given values
(7x – 27)=(3x + 29)
solve for x
7x-3x=29+27
4x=56
x=14
part b)
We know that
Supplementary angles are angles that their sum is equal to 180 degrees
so
A+B=180
substitute the given values
5x+25+x+17=180
solve for x
6x+42=180
6x=180-42
6x=138
x=23
Find the measure of Angle A
Opposite conjugate.
(-1/3) is (3/1)
Answer:
-3
Step-by-step explanation:
Slope of a line is "rise over run". Pick two points on the line. For example, (0,4) and (1,1). As we move from the first point to the second, we move down 3 units and right 1 unit. So the slope is -3/1 = -3.
Here's an algebraic approach. If the two points are (x₁, y₁) and (x₂, y₂), then the slope is:
m = (y₂ − y₁) / (x₂ − x₁)
Plugging in our two points:
m = (1 − 4) / (1 − 0)
m = -3
Answer:
Option C) population
Step-by-step explanation:
We are given the following situation in the question:
A researcher is curious about the average IQ of registered voters in the state of FL.
Sample:
It is a part of a population. It is always smaller than the population.
Statistic:
Any numerical value or any other measure describing a sample of a population is known as statistic.
Population:
It is the universal data set. Every observation belongs to this group which is of interest. Sampling is done within population to obtain small groups of sample.
Parameter:
Any numerical value or any other measure describing the population is known as a parameter.
In this situation, the entire group of registered voters in FL is an example of a population because it contains all the individual for variable of interest.
Variable of interest:
Average IQ of registered voters in the state of FL.
Individual of interest:
Registered voters in the state of FL.
