The presense of a midpoint will result in congruent segments.
What are congruent segments?Congruent segments are just equal-length line segments. Congruent means similar. Congruent line segments are typically represented by drawing the same number of little tic lines perpendicular to the segments in the middle of the segments.
A congruent line segment is any line segment with equal measure. Congruent line segments, for example, are the sides of an equilateral triangle since they all have the same length.
When we insert a midpoint to a line segment, it divides the line into two equal portions. Because equal segments are congruent, we can say that congruent segments are generated.

3. In a survey of 1000 eligible voters selected at random, it was found that 8% had a college degree. Additionally it was found that 80% of those who had a college degree voted in the last presidential election. Whereas 55% of the people who did not have a college degree voted in the last presidential election. Assuming that the poll is representative of all eligible voters, find the probability that an eligible voter selected at random voted. Draw a diagram to represent this situation.
a) If you randomly chose an eligible voter from this group, what is that probability that they have a degree and did not vote?
b) If you randomly chose an eligible voter from this group, what is the probability that they voted?
c) If you randomly chose a person who voted in the presidential election, what is the probability that they had a college degree?
hello, i'm sorry but i can't graph the diagram but here are the answers for a-c :)
A. 8%
B. 39.6%
C. 58.4%
step by step:
A. Calculation to determine the probability of The voter had a college degree and voted in the last presidential election.
P = 80/1,000
P=0.08*100
P=8%
Therefore the probability of The voter had a college degree and voted in the last presidential election will be 8%
B. Calculation to determine the probability of The voter did not have a college degree and did not vote in the last presidential election.
P =396/1000
P=0.396*100
P=39.6%
Therefore the probability of The voter did not have a college degree and did not vote in the last presidential election will be 39.6%
C. Calculation to determine the probability if The voter voted in the last presidential election.
P = 584/1,000
P=0.584*100
P=58.4%
Therefore the probability if The voter voted in the last presidential election will be 58.4%
The Tran family and the Campbell family each used their sprinklers last summer. The water output rate for the Tran family's sprinkler was 35 L per hour. The water output rate for the Campbell family's sprinkler was 25 L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 1925 L. How long was each sprinkler used?
The time in hours for the Tran family's sprinkler will be 30 hours.
The time in hours for the Campbell family's sprinkler will be 35 hours.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The water output rate for the Tran family's sprinkler was 35 L per hour.
The water output rate for the Campbell family's sprinkler was 25 L per hour.
And, The families used sprinklers for a combined total of 65 hours, which is resulting in a total water output of 1925 L.
Now,
Let time in hours for the Tran family's sprinkler = t
And, The time in hours for the Campbell family's sprinkler = 65 - t
So, We can formulate by the given condition,
⇒ 35t + 25 (65 - t) = 1925
Solve for t as;
⇒ 35t + 25 (65 - t) = 1925
⇒ 35t + 1625 - 25t = 1925
⇒ 10t + 1625 = 1925
⇒ 10t = 1925 - 1625
⇒ 10t = 300
⇒ t = 30
Thus, The time in hours for the Tran family's sprinkler = t
= 30 hours
And, The time in hours for the Campbell family's sprinkler = 65 - t
= 65 - 30
= 35 hours.
Therefore, we get;
The time in hours for the Tran family's sprinkler will be 30 hours.
The time in hours for the Campbell family's sprinkler will be 35 hours.

new york city is the most expensive city in the united states for lodging. the mean hotel room rate is $204 per night. assume that the room rates are normally distributed with a standard deviation of $55. answers to 3 decimals. what is the probability of more than $225?
The probability of more than $225 is 0.35197.
Here we need to find the probability of more than $225.
We need to calculate the z-score associated with x = $225
Z(score) = 225 - 204 / 55
= 0.381818
z(score) = 0.38
For z = 0.38 the corresponding probability is P(z < 0.38) = 0.64803.
Here we have to find the values greater than this value:
P(z > 0.38) = 1 - P (z < 0.38)
P( z > 0.38) = 0.35197
So the probability that a hotel room costs 225 or more per night is P (x > 225) = 0.35197 and the percentage is 35.197%.
Therefore the probability is 0.35197.

Using probability concepts, we calculated that the likelihood that the person plays the clarinet but not the flute is 0.2743.
What is conditional probability?The possibility of an event or outcome occurring based on the existence of a prior event or outcome is known as conditional probability. It is calculated by dividing the likelihood of the previous event by the likelihood of the subsequent, or contingent, event.
Here,
Finding people who can play the clarinet but not the flute is necessary. There are 172 people who can play the clarinet.
There are 47 people who can play both the clarinet and the flute.
As a result, 172-47=125 represents the number of people who can only play the clarinet and not the flute.
Probability(P),
P=( 125 / 350)
P=0.2743.
Therefore, the probability that a single person chosen at random can play clarinet but not flute is 0.2743.

An isosceles right triangle has a hypotenuse length that can be modeled with the function . the combined length of the legs can be modeled with the function l(x) = 2x. which function, p(x), can be used to find the perimeter of the triangle?
The perimeter of the isosceles triangle will be P(x) = x√2 + 2x.
A polygon with three sides is known as a triangle. The angles of a triangle add up to form 180° and the sum of all sides of a triangle is known as the perimeter. In an isosceles triangle, the two sides are equal and their opposite angle too. In an isosceles triangle, the hypotenuse side of the triangle can be written as h(x) = x√2. The combined length comes out to be L(x) = 2x. Using this information the perimeter of the triangle comes out to be,
P(x) = h(x) + L(x).
P(x) = x√2 + 2x
Hence the perimeter of the triangle comes out to be P(x) = x√2 + 2x

The equation of the linear function represented by the table would be y = 4x - 1.
What is the slope-intercept form of the line?
When you know the slope of the line to be examined and the point given is also the y-intercept, you can use the slope-intercept formula
y = mx + c.
The y value of the y-intercept point is represented by c in the formula.
By using the given table,
for x = 0 , y = -1
so by using the slope-intercept form of the line, we can write
y = mx + c
-1 = m(0) + c
c = -1 ----------(I)
Then for x = 1, y = 3
again by using the slope-intercept form of the line, we can write
y = mx + c
3 = m(1) + (-1) -----from (I)
3 = m - 1
⇒ m = 3 + 1
⇒ m = 4 -----------(II)
Now by using (I) and (II), we can make a linear function by using the slope-intercept form of the line
y = 4x - 1

It is false that " finding a random sample with a mean this low in a population with mean 7 and standard deviation 2 is very unlikely".
What is standard deviation?The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation indicates that the data are grouped around the mean, whereas a high standard deviation shows that the data are more dispersed. The average degree of variability in your data set is represented by the standard deviation. It reveals the average deviation of each score from the mean. The standard deviation gauges how widely the data deviates from the mean. When comparing data sets that may have the same mean but a different range, it is helpful. The mean of the two numbers 15, 15, 15, 14, 16 and 2, 7, 14, 22, 30 for instance, is the same. The second, however, is obviously more dispersed.

The height of the poster is 20 inches.
The original width of the poster was 6 inches. The original height of the poster was 4 inches. The size of the poster is scaled up. This is a transformation of the size of the poster. The width of the scaled-up poster is 30 inches. We need to find out the height of the scaled-up poster.
The scaling transformation preserves the shape of the object. This means the sides must still be in the same proportion. Let the constant of proportionality be represented by the variable "k".
30 = k*6
k = 30/6
k = 5
Hence, the poster is scaled up by a factor of five.
H = k*4
H = 5*4
H = 20
Hence, the height of the scaled-up poster is 20 inches.
