Answer:
we need a picture
Step-by-step explanation:
The solution is, First option and Third option. i.e. they are, "adjacent angles" & complementary angles",
What is an angle?
In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
You can observe in the figure that the angle 1 and the angle 2 have a common vertex and a common side.
These kind of angles are known as "adjacent angles".
You can observe that the intersection of the lines forms four equal anles which are right angles (Angles of 90 degrees).
Therefore, the angles 1 and 2 and also "complementary angles", because the sum of them is 90 degrees.
Then, the answers are the first option and the third option.

Cherries cost $5 for 2 pounds and $7.50 for 3 pounds.
What is the cost per pound?
b. Is it constant?
c. If you were to graph this situation, would you put weight or cost on the x-axis? Which one would you put on the y-axis?
d. Plot the two points described.
e. How much would 5 pounds of cherries cost? What did you do to solve this problem?
Answer:
Cherries cost $2.50 per pound
Yes, it is constant.
Weight would go on the x-axis and the cost would go on the y-axis.
The two points are (2, 5) and (3, 7.5)
5 pounds of cherries would cost $12.50. To solve the problem I multiplied the 5 pounds by 2.5, the cost per pound to find the cost.
Step-by-step explanation:
$5 for 2 pounds and $7.50 for 3 pounds can be turned into the points (2, 5) and (3, 7.5).
To find the cost per pound, input the two points into the slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{7.5-5}{3-2}[/tex]
Solve:
7.5 - 5 = 2.5
3 - 2 = 1
[tex]\frac{2.5}{1}[/tex] = 2.5
The cost of cherries per pound is $2.50. This is our slope.
The equation that represents the cost of cherries for x amount of pounds is:
y = 2.5x
To find how much 5 pounds of cherries would cost, replace x with 5 in the equation:
y = 2.5(5)
y = 12.5
5 pounds of cherries would cost $12.50.

(5, 4) & (2, c) slope is equal to 1/2
Please answer fast
Answer:
c = [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to [tex]\frac{1}{2}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (5, 4) and (x₂, y₂ ) = (2, c)
m = [tex]\frac{c-4}{2-5}[/tex] = [tex]\frac{c-4}{-3}[/tex] , then
[tex]\frac{c-4}{-3}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2(c - 4) = - 3
2c - 8 = - 3 ( add 8 to both sides )
2c = 5 ( divide both sides by 2 )
c = [tex]\frac{5}{2}[/tex]

A walk in interview 12% of Candidates can be selected and 28% of Canada can be put on hold for the next hiring date if 75 candidates are interviewed about how many are expected to be rejected
Answer:
45 candidates are expected to be rejected
Step-by-step explanation:
Here, we want to calculate the number of candidates to be rejected
The number of candidates to be rejected can be calculated from;
100% - (28% + 12%) = 60%
So 60% of the 75 interviewed are to be rejected
Thus, we have
60/100 * 75
= 45
The number of candidate expected to be rejected is 45 if the 12% of candidates can be selected and 28% of Canada can be put on hold for the next hiring date.
What is percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We have:
A walk in interview 12% of Candidates can be selected and 28% of Canada can be put on hold for the next hiring date if 75 candidates are interviewed.
Let's suppose total candidate is 100%
So,
= 100 - (12+28)
= 60%
Number of candidate expected to be rejected:
= 60% of 75
= (60×75)/100
= 45
Thus, the number of candidate expected to be rejected is 45 if the 12% of candidates can be selected and 28% of Canada can be put on hold for the next hiring date.

Find the slope of each line.
1)
(-1, 1), (-1, 4)
Answer:
The slope is undefined
Step-by-step explanation:
The equation of the line is x=-1 and this equation’s slope is undefined because it’s a vertical line.
Hope this helps and answers your question :)
Answer:
The line presented has an undefined slope.
Step-by-step explanation:
We are given two points of a line: (-1, 1) and (-1, 4).
Coordinate pairs in mathematics are labeled as (x₁, y₁) and (x₂, y₂).
The x-coordinate is the point at which if a straight, vertical line were drawn from the x-axis, it would meet that line.The y-coordinate is the point at which if a straight, horizontal line were drawn from the y-axis, it would meet that line.Therefore, we know that the first coordinate pair can be labeled as (x₁, y₁), so, we can assign these variables these "names" as shown below:
x₁ = -1y₁ = 1We also can use the same naming system to assign these values to the second coordinate pair, (-1, 4):
x₂ = -1y₂ = 4We also need to note the rules about slope. There are different instances in which a slope can either be defined or it cannot be defined.
Circumstance 1: As long as the slope is not equal to zero, there can be a
positive slope, [tex]\frac{1}{3}[/tex]negative slope, [tex]-\frac{5}{6}[/tex]Circumstance 2: If the slope is completely vertical (there is not a "run" associated with the line), there is an undefined slope. This is the slope of a vertical line. An example would be a vertical line (the slope is still zero).
Circumstance 3: If the line is a horizontal line (the line does not "rise" at all), then the slope of the line is zero.
Therefore, a slope can be positive, negative, zero, or undefined.
Now, we need to solve for the line we are given.
The slope of a line is determined from the slope-intercept form of an equation, which is represented as [tex]\text{y = mx + b}[/tex].
The slope is equivalent to the variable m. In this equation, y and x are constant variables (they are always represented as y and x) and b is the y-intercept of the line.
We can do this by using the coordinates of the point and the slope formula given two coordinate points of a line: [tex]m=\frac{y_2-y_1}{x_2-x_1}.[/tex]
Therefore, because we defined our values earlier, we can substitute these into the equation and solve for m.
Our values were:
x₁ = -1y₁ = 1x₂ = -1y₂ = 4Therefore, we can substitute these values above and solve the equation.
[tex]\displaystyle{m = \frac{4 - 1}{-1 - -1}}\\\\m = \frac{3}{0}\\\\m = 0[/tex]
Therefore, we get a slope of zero, so we need to determine if this is a vertical line or a horizontal line. Therefore, we need to check to see if the x-coordinates are the same or if the y-coordinates are the same. We can easily check this.
x₁ = -1
x₂ = -1
y₁ = 1
y₂ = 4
If our y-coordinates are the same, the line is horizontal.
If our x-coordinates are the same, the line is vertical.
We see that our x-coordinates are the same, so we can determine that our line is a vertical line.
Therefore, finding that our slope is vertical, using our rules above, we can determine that our slope is undefined.

Answer:
1=35 find angle 2 80+65-180=35
2= 65 vertical angles are congruent ex 115-180
3=29 ex. 90+65-180=29
4= 115 vertical angle congruent
5=65 vertical angles are congruent ex 115-180
6=65 35+80-180=65
7=144
Answer:
∠1 = 35 ; ∠2 = 65 ; ∠3 = 29 ; ∠4 = 115
∠5 = 65 ; ∠6 = 36 ; ∠7 = 144
Step-by-step explanation:
∠4 = 115 {Vertically opposite angles}
∠5 + 115 = 180 {linear pair}
∠5 = 180 - 115
∠5 = 65
∠2 = ∠5 {Vertically opposite angles}
∠2 = 65
∠1 + 80 +∠2 = 180 {Angle sum property of triangle}
∠1 + 80 + 65=180
∠1 + 145 = 180
∠1 = 180 - 145
∠1 = 35
∠5 + ∠7 + 90 + 61 = 360 {angle sum property of quadrilateral}
65 + ∠ 7 + 90 + 61 = 360
∠7 + 216 = 360
∠7 = 360 - 216
∠7 = 144
∠6 + ∠ 7 = 180 {linear pair}
∠6 + 144 = 180
∠6 = 180 - 144
∠6 = 36
∠3 + ∠4 +∠ 6 = 180 {angle sum property of triangle}
∠3 + 115 + 36 = 180
∠3 + 151 = 180
∠3 = 180 - 151
∠3 = 29

Directional selection is occurring because the graph favors an extreme.
Stabilizing selection is occurring because the average is favored.
Disruptive selection is occurring because the two extremes are favored.
Biodiversity variation is occurring because there is an increase in trait variation.
Stabilizing selection is occurring because the average is favored.
If its the same graph im thinking of.
The correct statement is a valid claim that could be made using the data in the graph is,
B) Stabilizing selection is occurring because the average is favored.
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.
Now, On this graph we can observe the workings of the stabilizing selection.
Since, Stabilizing selection tends to favor the average phenotype and eliminate the extremes.
Essentially, this means that the natural selection is selecting the mean value of a trait as optimal.
Hence, In our case, the mean weight of newborns is selected as optimal, because newborns born with less weight can be too weak to survive and the ones that have too much weight (are too big) can hurt the mother during birth.
Thus, The correct statement is a valid claim that could be made using the data in the graph is,
B) Stabilizing selection is occurring because the average is favored.
