To find the system of equation, we will put the values given tables in the equation given in the options.
For option (1)
y = 1.75x + 3.5 (For line F)
let's take the point (2,7) and put in the equation,
y = 1.75*2 + 3.5
= 3.5 +0.35
= 7
which is true.
Hence, (2,7) satisfies the equation.
y = -4x-8 (For line G)
lets take the point (-3,4) and put in the equation,
y = (-4)*(3) - 8
= 12 - 8
= 4
which is true.
Hence, (-3,4) satisfies the equation.
Therefore, Equation for line F is y = 1.75x + 3.5 and equation for line G is y = -4x-8.

Last year's freshman class at State University total 5,320 students. Of those 1,262 received a merit scholarship to help offset tuition costs. The amount a student received was N($3,450 , $480). if the cost of a full tuition was $4,050 last year , what percentage of students who received a merit scholarship did not receive enough to cover full tuition ? ( Round to nearest whole percent)Percentage of students ________%
Answer: We need to find the percentage of students that received a scholarship that did not cover their full tuition:
The number of students that received a scholarship was:
[tex]1262[/tex]The amounts that students received were:
[tex]\begin{gathered} 3,450\text{ Dollars} \\ 480\text{ Dollars} \end{gathered}[/tex]But the actual tuition cost was:
[tex]4050\text{ Dollars}[/tex]Therefore, none of the students that received scholarship had received enough to cover the full tuition, because:
[tex]\begin{gathered} 4050>3450 \\ 4050\text{ }>480 \end{gathered}[/tex]So, 100% of the students that received scholarships, did not receive enough to cover their tuition.

[tex]\begin{gathered} \frac{2}{11}\times\frac{1}{2} \\ =\frac{1}{11} \\ =0.909090\ldots \end{gathered}[/tex]The two shorter sides of a right triangle measure 18 ft and 24 ft. What is the measure in feet of the third side?
We have that in a right triangle, the larger side is the hypothenuse since the sum of the others angles must be equal to 90. Thus, we can apply the Pythagorean Theorem to solve this question.
The legs of the triangle are a = 18 ft, b = 24 ft, and c = ?.
Then, applying the Pythagorean Theorem, we have (without using units):
[tex]c^2=a^2+b^2\Rightarrow c^2=(18)^2+(24)^2\Rightarrow c^2=324+576\Rightarrow c^2=900[/tex]Then, taking the square root to both sides of the equation, we have:
[tex]\sqrt[]{c^2}=\sqrt[]{900}\Rightarrow c=30[/tex]Then, the measure of the third side (hypothenuse) is c = 30 ft.

[tex]A=P(1-r)^t[/tex]where,
A: price of the iphone after t years
P: initial price = 1099
r: rate of percetage decrease in decimal for = 0.25

Find an equation for the perpendicular bisector of the line segment whose endpoints are (-2,1) and (-6,5)
Here, we want to find the equation of the perpendicular bisector of th line segment with the given endpoints
We start by calculating the slope of the line segment
Mathematically, we can have that as;
[tex]\begin{gathered} m\text{ = }\frac{y_2-y_1}{x_2-x_1} \\ \\ m\text{ = }\frac{5-1}{-6-(-2)}=\text{ }\frac{4}{-4}\text{ = -1} \end{gathered}[/tex]So, we have the slope of the line as -1
Mathematically, the slopes of two lines which are perpendicular to each other have a product of -1
Thus;
[tex]\begin{gathered} m_2\text{ }\times\text{ (-1) = -1} \\ \\ m_2\text{ = 1} \end{gathered}[/tex]Now, we need the midpoint segment coordinates as it is the point through which the perpendicular bisector will pass through
We can get these coordinates using the mid-point formula
That will be;
[tex]\begin{gathered} (x,y)\text{ = (}\frac{x_2+x_1}{2},\frac{y_2+y_1}{2}) \\ \\ (x,y)\text{ = (}\frac{-2-6}{2},\frac{1+5}{2}) \\ \\ (x,y)\text{ = (-4,3)} \end{gathered}[/tex]So we use the point-slope formula to get the equation
That will be;
[tex]\begin{gathered} y-y_1=m(x-x_1) \\ y-3\text{ = 1(x+4)} \\ y-3\text{ = x + 4} \\ y\text{ = x + 4 + 3} \\ y\text{ = x + 7} \end{gathered}[/tex]Given cos = 0.9528, find .
Given:

1 Lola collects blood donations at a clinic. 7/16 of the donations are of Type 0, 3/8 are of Type A, and 1/16 are Type AB. The remaining are Type B. What part of the blood donations are Type B?
Answer:
n=1/8
Explanation:
From the diagram, if we sum up all the parts, we have:
[tex]\frac{7}{16}+\frac{3}{8}+\frac{1}{16}+n=1[/tex]We solve the equation above for n.
The lowest common multiple of 16 and 8 = 16
Therefore:
[tex]\frac{7+6+1}{16}+n=1[/tex]Therefore:
[tex]\begin{gathered} \frac{14}{16}+n=1 \\ n=1-\frac{14}{16} \\ n=\frac{16-14}{16} \\ n=\frac{2}{16} \\ n=\frac{1}{8} \end{gathered}[/tex]The value of n is 1/8.
Order from Greatest to Least -2.30 , -13/4,-3 1/8,-14/5
According to the given data we have the following numbers:
-2.30 , -13/4,-31/8,-14/5
To order from Greatest to Least the above numbers first we would have to divide the numerator by the denominator of each of the fractions so we can get the decimal number and so it would be easier to order the numbers.
So:
-13/4=-3.25
-31/8=-3.875
-14/5=-2.8
Therefore, the Order from Greatest to Least of the numbers would be:
-2.30,-14/5,-13/4,-31/8

The slope of a graph is ratio of the change in the y - variable to the change in the x - variable True or false
ANSWER
True
EXPLANATION
We want to understand the meaning of slope.
The slope of a graph is known as the rate of change of the dependent variable with the independent variable.
It is the rate of change of the graph.
This means that it tells us how the y values of the graph vary with the x values.
Therefore, the slope of a graph is ratio of the change in the y - variable to the change in the x - variable.

Your statistics class has 26 students in it - 14 girls and 12 boys. Your teacher uses a calculator to select two students at random to solve a problem on the board. Given that the second student chosen is a girl, what is the probability that the first student was also a girl?
The probability that the first student was also a girl is 0.175.
What is probability?Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true.
The fraction of choosing a girl will be:
= Number of girls / Number of students
= 14 / 26
= 7/13
Therefore, the probability of having both girls will be:

Exercise #1: We would like to find the distance between points A and B if they have coordinates A(2,3) and B(14, 12). B (a) Sketch the right triangle below that could be used to calculate the length of AB and find its length using the Pythagorean Theorem. (b) How could we calculate the lengths of the legs of the right triangle in (a) from the coordinates of points A and B.
Answer
Check Explanation
Explanation
We've been asked to find the length of the distance between points A (2, 3) and B (14, 12).
a) First of, we've been asked to sketch the right angle triangle that coulb be used to calculate the distance AB
The sketch will be shown below
So, the figure above represents the right angle triangle that can be used to calculate the distance AB
Distance AB = hyp = ?
Distance between the x-coordinates of points A and B = x = 14 - 2 = 12
Distance between the y-coordinates of points A and B = y = 12 - 3 = 9
The Pythagoras Theorem is used for right angled triangle, that is, triangles that have one of their angles equal to 90 degrees.
The side of the triangle that is directly opposite the right angle or 90 degrees is called the hypotenuse. It is normally the longest side of the right angle triangle.
The Pythagoras theorem thus states that the sum of the squares of each of the respective other sides of a right angled triangle is equal to the square of the hypotenuse. In mathematical terms, if the two other sides are x and y respectively,
x² + y² = (hyp)²
For this question,
x = 12 units
y = 9 units
hyp = AB = ?
x² + y² = (hyp)²
12² + 9² = AB²
144 + 81 = AB²
225 = AB²
We can rewrite this as
AB² = 225
Take the square root of both sides
√(AB²) = √(225)
AB = 15 units
b) The second part of the question asks how we calculated the legs of the right angle triangle that we used to solve this distance between AB.
Since both points lie on given x and y axis levels in the coordinate system, the length of the legs of this right angle triangle is obtained simply by taking the difference between respective x and y coordinates.
For the base of the triangle,
Distance between the x-coordinates of points A and B
= x
= 14 - 2
= 12 units
For the height of the triangle,
Distance between the y-coordinates of points A and B
= y
= 12 - 3
= 9 units
Hope this Helps!!!
