Three students are working to find the solution set of this system of equations: y = 3x + 10 2y = 6x – 4
Answer:
hope this helps!
Step-by-step explanation:
The solution set of the given system of equations y = 3x + 10 and 2y = 6x – 4 is empty, indicating that the lines are parallel and do not intersect.
Explanation:To find the solution set of the system of equations y = 3x + 10 and 2y = 6x – 4, we can solve the equations simultaneously by substitution or elimination method.
Using the substitution method:
Step 1: Substitute the value of y from the first equation into the second equation. 2(3x + 10) = 6x – 4.Step 2: Simplify the equation: 6x + 20 = 6x – 4.Step 3: Combine like terms and isolate the variable: 6x - 6x = -4 - 20.Step 4: Simplify further: 0 = -24.Step 5: Since 0 does not equal -24, the system of equations does not have a solution.Therefore, the solution set of the system of equations y = 3x + 10 and 2y = 6x – 4 is empty, indicating that the lines represented by the equations do not intersect and are parallel.

4-13 Students in a management science class have just re- ceived their grades on the first test. The instructor has provided information about the first test grades in some previous classes as well as the final average for the same students. Some of these grades have been sampled and are as follows:STUDENT 1 2 3 4 5 6 7 8 9 1st test grade 98 77 88 80 96 61 66 95 69 Finalaverage 93 78 84 73 84 64 64 95 76 (a) Develop a regression model that could be used to predict the final average in the course based on the first test grade. (b) Predict the final average of a student who made an 83 on the first test. (c) Give the values of r and r2 for this model. Inter- pret the value of r2 in the context of this problem
Answer:
a) y = 0.74x + 18.99; b) 80; c) r = 0.92, r² = 0.85; r² tells us that 85% of the variance in the dependent variable, the final average, is predictable from the independent variable, the first test score.
Step-by-step explanation:
For part a,
We first plot the data using a graphing calculator. We then run a linear regression on the data.
In the form y = ax + b, we get an a value that rounds to 0.74 and a b value that rounds to 18.99. This gives us the equation
y = 0.74x + 18.99.
For part b,
To find the final average of a student who made an 83 on the first test, we substitute 83 in place of x in our regression equation:
y = 0.74(83) + 18.99
y = 61.42 + 18.99 = 80.41
Rounded to the nearest percent, this is 80.
For part c,
The value of r is 0.92. This tells us that the line is a 92% fit for the data.
The value of r² is 0.85. This is the coefficient of determination; it tells us how much of the dependent variable can be predicted from the independent variable.
To predict the final average based on the first test grade, you can use the regression equation Final average = 173.51 + 4.83(First test grade). For a student who scored 83 on the first test, the predicted final average is 179.08. The correlation coefficient, r, is 0.868 and the coefficient of determination, r^2, is 0.752.
Explanation:To develop a regression model to predict the final average based on the first test grade, you can use the least-squares regression line. The equation for the regression line is: Final average = 173.51 + 4.83(First test grade). This equation allows you to predict the final average based on the first test grade.
To predict the final average for a student who scored 83 on the first test, substitute 83 into the equation: Final average = 173.51 + 4.83(83) = 179.08. Therefore, the predicted final average is 179.08 for a student who scored 83 on the first test.
The correlation coefficient, r, measures the strength and direction of the linear relationship between the first test grade and the final average. In this model, the value of r is 0.868. The coefficient of determination, r^2, represents the proportion of the variation in the final average that can be explained by the first test grade. In this model, the value of r^2 is 0.752. This means that 75.2% of the variation in the final average can be explained by the first test grade.

You deposit $300 in an account earning 5% interest compound annually. How much will you have in the account after 10 years
Answer:
450
Step-by-step explanation:
5% of 300 = 15
300+10(15)=450
Using the compound interest formula, if you deposit $300 in an account earning 5% interest compounded annually, you would have approximately $488.85 in the account after 10 years.
Explanation:This problem involves compound interest, which appeal to financial maths. The formula for compound interest is A = P*(1 + r/n)^(nt), where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (in decimal).n is the number of times that interest is compounded per year.t is the time the money is invested for, in years.For this problem, P = $300, r = 5% or 0.05, n = 1 (because it's compounded annually), and t = 10 years. Substituting these values into the formula, you have A = 300*(1 + 0.05/1)^(1*10).
Doing the math, A = $300 * (1.05)^10 ≈ $488.85. So after 10 years, you would have approximately $488.85 in the account.

Find two positive even consecutive integers such that the square of the smaller integer is 10 more than the larger integer
Answer:
the numbers are [tex]4,6[/tex]
Step-by-step explanation:
Let
x-------> the smaller even consecutive integer
x+2-------> the larger even consecutive integer
we know that
[tex]x^{2}=(x+2)+10[/tex]
solve for x
[tex]x^{2}-x-12=0[/tex]
The formula to solve a quadratic equation of the form [tex]ax^{2} +bx+c=0[/tex] is equal to
[tex]x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}[/tex]
in this problem we have
[tex]x^{2}-x-12=0[/tex]
so
[tex]a=1\\b=-1\\c=-12[/tex]
substitute in the formula
[tex]x=\frac{1(+/-)\sqrt{-1^{2}-4(1)(-12)}} {2(1)}[/tex]
[tex]x=\frac{1(+/-)\sqrt{49}} {2}[/tex]
[tex]x=\frac{1(+/-)7} {2}[/tex]
[tex]x=\frac{1(+)7} {2}=4[/tex] ------> the solution (must be positive)
[tex]x=\frac{1(-)7} {2}=-3[/tex]
therefore
the numbers are [tex]4,6[/tex]
Two positive even consecutive numbers are [tex]4,6[/tex].
Let [tex]x,\;x+2[/tex] are two positive consecutive even number.
According to question,
[tex]x^2=(x+2)+10[/tex]
[tex]x^2-x-12=0[/tex]
Solve the quadratic equation,
[tex]x^2-4x+3x-12=0\\x(x-4)-3(x-4)=0\\(x-4)(x-3)=0\\\; x-4=0\\ \; x-3=0\\[/tex]
So [tex]x=3 , 4[/tex].
Positive even number is the requirement so [tex]3[/tex] is not a even number so eliminate.

For every pizza Eric's family ate, eric ate2 of the 8 pieces. If Eric's family bought 2 pizzas, write the ratio of the total number of pieces Eric ateto the total number of pieces the family ate.
Answer:
4 over sixteen, or 4/16 is your answer.
Step-by-step explanation:
There are 2 pizzas, each of which contain 8 pieces. So, in all, there were 8 pieces. Eric ate two pieces from each pizza. So, 2+2=4. Thus, he ate four out of the 16 pieces. That brings us to our answer, 4/16.
I hope this helps you, have a wonderful day!
Final answer:
The ratio of the total number of pieces Eric ate to the total number of pieces eaten by his family when they bought 2 pizzas, is 1:4, meaning Eric eats 1 out of every 4 pieces.
Explanation:
For every pizza Eric's family ate, Eric ate 2 of the 8 pieces. If Eric's family bought 2 pizzas, to find the ratio of the total number of pieces Eric ate to the total number of pieces the family ate, we start by calculating the total pieces in 2 pizzas and the pieces Eric ate.
Each pizza has 8 pieces, so 2 pizzas have 8 * 2 = 16 pieces in total.
Since Eric eats 2 pieces per pizza, for 2 pizzas, he would eat 2 * 2 = 4 pieces in total.
Therefore, the ratio of the pieces Eric ate to the total pieces is:
4 (pieces Eric ate) : 16 (total pieces), which simplifies to 1:4.
This ratio means that for every piece of pizza Eric eats, there are 4 pieces total, indicating Eric eats 1 out of every 4 pieces.

Step 4 To minimize the product f(x) = x2 + 102x, we must solve 0 = f '(x) = 2x + 102, which means x = -51 Correct: Your answer is correct. seenKey -51 . Step 5 Since f ''(x) = 2 , there must be an absolute minimum at x = −51. Thus, the two numbers are as follows. (smaller number) (larger number)
Answer:
The two numbers would be -51 and 51
Step-by-step explanation:
To find these, first set the equation for the first number as x. You can then set the second number as x + 102. Now, find their product.
x(x + 102) = x^2 + 102x
Now, to find the minimum, find the value of x in the vertex of this equation.
-b/2a = -102/2(1) = -102/2 = -51
So we know -51 is the first number. Now we find the second using the prewritten equation.
x + 102 = -51 + 102 = 51
The two numbers whose difference is 102 and whose product is a minimum are -51 and 51. This is obtained by differentiating and finding the minimum of the function that represents their product.
Explanation:To find two numbers whose difference is 102 and whose product is a minimum, we initially express the two numbers as x and x + 102. The product of these two numbers can be denoted as f(x) = x(x + 102) = x² + 102x. To find the minimum product, we differentiate f(x) to find f'(x) = 2x + 102. Setting this equal to zero gives x = -51. We should note, f''(x) = 2, verifies that there is a minimum at x = -51. Hence, the two numbers are -51 and (-51 + 102) = 51.

are you trying to combine them?
if so, then when you multiply parenthesis stuffs, you should FOIL.
foil stands for first, outside, inside, and last.
when we combine (x -2)(3x-4)
1. we multiply the first parts together x & 3x to get 3x^2.
2. then we multiply the "outsides," x & -4 to get -4x.
3. insides would be -2 & 3x, so -6x.
4. finally last is -2 & -4 to make 8.
putting it all together we get 3x^2 - 4x - 6x + 8.
or simply 3x^2 - 10x + 8 by combing like terms.
for (x + 6)^2 keep in mind that squaring is multiplying something by itself. so (x+6)^2 is the same as (x+6)(x+6).
applying the same foil technique:
1. x * x = x^2
2. x * 6 = 6x
3. 6 * x = 6x
4. 6 * 6 = 36
so we get x^2 + 6x + 6x + 36.
simplified it's x^2 + 12x + 36
keep in mind also that FOILing is only really good for binomials. (something like (x+6)(6x^2+7x+6) wouldnt work).
also also remember that all were really doing is just distributing

A cardboard box without a top is to have volume 62500 cubic cm. find the dimensions which minimize the amount of material used.
The dimensions of the box that minimize the amount of material used are approximately 39 cm by 39 cm by 39 cm.
To minimize the amount of material used, we need to minimize the surface area of the box.
Let's denote the dimensions of the box as x,y, and z, where x and y are the dimensions of the base (length and width), and z is the height.
The volume V of the box is given by:
[tex]\[ V = xyz \][/tex]
We're given that V = 62500 cubic cm.
The surface area A of the box (excluding the top) is given by:
[tex]\[ A = xy + 2xz + 2yz \][/tex]
To minimize the amount of material used, we need to minimize A subject to the constraint V = 62500 .
We can solve this problem using the method of Lagrange multipliers. First, let's define the Lagrangian function L as follows:
[tex]\[ L(x, y, z, \lambda) = xy + 2xz + 2yz + \lambda(62500 - xyz) \][/tex]
Now, we take partial derivatives of L with respect to x,y,z, and [tex]\( \lambda \),[/tex] and set them equal to zero:
[tex]\[ \frac{\partial L}{\partial x} = y + 2z - \lambda yz = 0 \]\[ \frac{\partial L}{\partial y} = x + 2z - \lambda xz = 0 \]\[ \frac{\partial L}{\partial z} = 2x + 2y - \lambda xy = 0 \]\[ \frac{\partial L}{\partial \lambda} = 62500 - xyz = 0 \][/tex]
Solving these equations will give us the dimensions that minimize the amount of material used.
However, this system of equations is quite complex to solve manually. Let's simplify the problem by recognizing that the dimensions that minimize the amount of material used will likely be those where the box is as close to a cube as possible. This means x=y to minimize the perimeter, and x=y=z to minimize the surface area.
So, let's find the cube root of 62500 :
[tex]\[ \sqrt[3]{62500} \approx 38.99 \][/tex]
Since [tex]\( 38^3 = 54872 \)[/tex] and [tex]\( 39^3 = 59319 \)[/tex], the closest perfect cube to 62500 is [tex]\( 39^3 \)[/tex]. Therefore, the dimensions of the box that minimize the amount of material used are approximately 39 cm by 39 cm by 39 cm.

What is Addition?
Addition (usually denoted by a plus sign +) is one of the four basic arithmetic operations, the other three being subtraction, multiplication, and division. Adding two integers gives the sum or sum of their values. The example in the adjacent image shows a combination of three apples and two apples, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" (ie "3 plus 2 equals 5").
In addition to counting items, addition can also be defined and performed without reference to specific objects, using instead abstractions called numbers, such as integers, real numbers, and complex numbers. Addition belongs to arithmetic, a branch of mathematics. In algebra, another branch of mathematics, addition can also be performed on abstract objects such as vectors, matrices, subspaces, and subgroups.
Addition has several important properties. It is commutative, which means that the order of the operands does not matter, and it is associative, which means that if you add more than two numbers, the order of addition does not matter (see Addition). Repeated addition of 1 is the same as counting (see successor function). Adding 0 does not change the number. Addition also follows predictable rules for related operations like subtraction and multiplication.
Here given,Susie has 8 pieces of string and 3 pieces are 7.8 inches long ,and 5 pieces are 9.2 inches long.

Which equation listed below, when solved, shows how to find the circumference of a circle if the diameter is 6 inches? Use 3.14 for pi
Answer:
C = π(6)
C = 6π
C = 18.84
Step-by-step explanation:
The circumference is the distance around the circle. It relates the number of times the diameter will encircle the circumference as 3.14 or π. As a result, the formulas for the circumference of a circle are C = 2πr or C = πd. The information given is the diameter so use C = πd by substituting d = 6.
C = π(6)
C = 6π
C = 18.84

A pyramid has a cross-sectional shapes, taken parallel to its base, that are _____ to one another
Answer: similar
Step-by-step explanation: apex
Answer:
The fill in the blank is the word similar.
Step-by-step explanation:
A pyramid has a cross-sectional shapes, taken parallel to its base, that are similar to one another.
When we do the cross-section of a pyramid parallel to its base, the cross-section formed will be in the same shape like the base.
Whenever a cross section is done parallel to the base of any pyramid, the resulting shape will be same like the base. As we move up in the pyramid and cross section it, the shape formed will be like the base but with smaller dimensions. But the shape will be the same as the base.
