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:

Bob bought a $800 TV on sale for $650. What is the percent he saved?
Answers
Answer:
18.75%
Step-by-step explanation:
Since you want to know what percent he saved, first you have to figure out how much he saved.
800 - 650 = 150
Then to find the percent, find how much 150 is of 800.
[tex]\frac{150}{800} = 0.1875[/tex]
Since we're finding a percentage, multiply by a 100.
0.1875 × 100 = 18.75%
If it said to round, the answer would be 19%, but it doesn't, so keep it at 18.75%.
The scatter plot shows the number of hours worked, x, and the amount of money spent on entertainment, y, by each of 25 students.Use the equation of the line of best fit, =y+1.82x11.36, to answer the questions below.Give exact answers, not rounded approximations. (a) For an increase of one hour in time worked, what is the predicted increase in the amount of money spent on entertainment?$(b) What is the predicted amount of money spent on entertainment for a student who doesn't work any hours?$(c) What is the predicted amount of money spent on entertainment for a student who works 8 hours?$
Answers
Solution:
Given the scatterplot below:
where the equation of the line of best fit is expressed as
[tex]y=1.82x+11.36[/tex]A) Predicted increase in the amount of money spent on entertainment, for an increase of one hour in time worked.
Recall that the line equation is expressed as
[tex]\begin{gathered} y=mx+c \\ where \\ m=slope \\ slope=\frac{increase\text{ in y}}{increase\text{ in x}} \end{gathered}[/tex]By comparison with the equation of line of best fit, we see that
[tex]\begin{gathered} slope=1.82 \\ where \\ slope=\frac{increase\text{ in amout of money spent}}{increase\text{ in the number of hours worked}} \end{gathered}[/tex]Thus, we have
[tex]\begin{gathered} 1.82=\frac{increase\text{ in amount of money spent}}{1} \\ \Rightarrow predicted\text{ increase in amount of money spent on entertainment = \$1.82} \end{gathered}[/tex]B) Predicted amount of money spent on entertainment for a student with no number of hours worked
This implies that from the equation of the line of best fit, the value of x is zero.
By substitution, we have
[tex]\begin{gathered} y=1.82(0)+11.36 \\ =0+11.36 \\ \Rightarrow y=\$11.36 \end{gathered}[/tex]C) Predicted amount of money spent on entertainment for a student with8 hours of work.
Thus, we have the value of x to be 8 from the equation of the line of best fit.
By substitution, we have
[tex]\begin{gathered} y=1.82\left(8\right)+11.36 \\ =14.56+11.36 \\ \Rightarrow y=\$25.92 \end{gathered}[/tex]А.

Marisol wants to buy a backpack from the Gucci store. Gucci ishaving a sale of 45% off the regular price. If the regular price of aGucci backpack is $1375.23, then what will the new sale price beafter the discount of 45% is applied?
Answers
Regular price = $1375.23
Discount = 45% of Regular price
The discount = 45% of $1375.23
= 45/100 x $1375.23
= 0.45 x $1375.23
Discount = $ 618.85
But Sale price = Regular price - Discount
Sale price = $1375.23 - $618.85
Sale price = $756.38
Hence, the new sale price after the discount of 45% is applied is $756.38

Answers
The system of equation that represents lines F and G is (1) y = 1.75x + 3.5, y = -4x-8
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.

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?
Answers
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:

5 2/5 × 0.8A. 4.32B. 5.76C.7.80D.2.75
Answers
Answer:
A. 4.32
Explanation:
First, we need to transform the mixed number 5 2/5 into a decimal number as:
[tex]5\frac{2}{5}=5+\frac{2}{5}=5+0.4=5.4[/tex]Then, we can multiply 5.4 by 0.8, so:
[tex]5\frac{2}{5}\times0.8=5.4\times0.8=4.32[/tex]To multiply 5.4 by 0.8, we can multiply the numbers normally without taking into account the decimal points. So 54 times 08 is equal to:
Then, 5.4 has one digit after the decimal point and 0.8 has one digit after the decimal point. So, in total, we have two digits after the decimal point. It means that the result is equal to 4.32 because we need two digits after the decimal point.
Therefore, the answer is 4.32
The two shorter sides of a right triangle measure 18 ft and 24 ft. What is the measure in feet of the third side?
Answers
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.

5|2x + 1| – 3 ≤ 7
Find
Solve the inequality
Explanation
[tex]\begin{gathered} 5|2x+1|-3\leq7 \\ 5|2x+1|\leq7+3 \\ 5\lvert2x+1\rvert\leq10 \\ |2x+1|\leq\frac{10}{5} \\ \\ |2x+1|\leq2 \end{gathered}[/tex]we know that
[tex]2x+1\leq2\text{ }and\text{ }2x+1>-2[/tex]so ,
[tex]\begin{gathered} 2x+1\leq2 \\ 2x\leq1 \\ x\leq\frac{1}{2} \\ \\ and \\ \\ 2x+1\ge-2 \\ 2x\ge-2-1 \\ 2x\ge-3 \\ x\ge-\frac{3}{2} \end{gathered}[/tex]so ,
[tex]-\frac{3}{2}\leq x\leq\frac{1}{2}[/tex]Final Answer
Hence , the correct option is
[tex]-\frac{3}{2}\leq x\leq\frac{1}{2}[/tex]Jeremiah can drink 64 fluid ounces of coffee in 4 days. How many Quarts of coffee can he drink in 1 hour.help explain please:)
Answers
1 quart = 32 fluid ounces
Therefore, 64 fluid ounces = 2 quarts
Jeremiah can drink these 2 quarts in 4 days meaning he drinks
[tex]2\frac{\text{quarts}}{4\text{days }}=0.5\frac{\text{quarts}}{\text{days}}[/tex]Now, there are 24 hours in a day; therefore, the number of quarts Jeremiah drinks in 1 hour is
[tex]\frac{0.5\text{quarts}}{24\text{hours}}=\frac{1}{48}\frac{\text{quarts}}{\text{days}}[/tex]or in decimal form, this is 0.021 quarts in an hour.
Solve the following exponential equation. Express irrational solutions in exact form and as a decimal rounded to three decimal places. 4^-x=2.6What is the exact answer? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.A. The solution set { } (simplify your answer. type an exact answer)B. There is no solution

Given:
[tex]4^{-x}=2.6[/tex]To solve for x:
Taking log on both sides
[tex]\begin{gathered} \log 4^{-x}=\log 2.6 \\ -x\log 4=\log 2.6 \\ -x=\frac{\log 2.6}{\log 4} \\ -x=0.689255811 \\ x=-0.689255811 \\ x\approx-0.689 \end{gathered}[/tex]Hence, the value of x is -0.689 (rounded to three decimal places).

Answers
Given that R(x, y) = (-y, x)
This is a transformation.
We want to find R(Q)
The point Q is given as:
Q = (1, 0)
This means that x = 1 and y = 0
Therefore, for R(Q):
-y = -0 = 0
x = 1
Therefore:
R(Q) = (-y, x) = (0, 1)
