Answer:
The amount of saving is Rs.1000.
Step-by-step explanation:
Solution :
Let the,
>> Expenditure = 3x>> Saving = 2xSo, solving for x.
\({\dashrightarrow{\tt{Expenditure + Saving = 2500}}}\)
\({\dashrightarrow{\tt{3x + 2x = 2500}}}\)
\({\dashrightarrow{\tt{5x = 2500}}}\)
\({\dashrightarrow{\tt{x = 2500 \div 5}}}\)
\({\dashrightarrow{\tt{x = \dfrac{2500}{5}}}}\)
\({\dashrightarrow{\tt{x = \cancel{\dfrac{2500}{5}}}}}\)
\({\dashrightarrow{\tt{x =500}}}\)
\({\star{\underline{\boxed{\tt{\red{x =500}}}}}}\)
Hence, the value of x is 500.
Thus,
>> Expenditure = 3 × 500 = Rs.1500>> Saving = 2 × 500 = Rs.1000\( \rule{300}{1.5}\)
Find the solution of the system of equations. -4x - y = -28
x+y=4
The solutions of the system of equations are 8 and -4.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 9 is an equation.
We have,
-4x - y = -28 _____(1)
x + y = 4 _____(2)
x = 4 - y _____(3)
Substituting (3) in (1) we get,
-4(4 - y) - y = -28
-16 + 4y - y = -28
-16 + 3y = -28
3y = -28 + 16
3y = -12
y = -4
Substituting y = -4 in (3) we get,
x = 4 - (-4)
x = 4 + 4
x = 8
Thus,
The value of x is 8.

Correlation is a measure of the extent to which two factors Group of answer choices vary together. are random samples. influence each other. are dependent variables.
Correlation is a measure of the extent to which two factors vary together. Correlation denotes the relationship between two variables. Correlation analysis determines the strength and direction of the linear relationship between two variables. Correlation can be positive, negative, or neutral.
Positive correlation denotes that the variables move together in the same direction, whereas negative correlation denotes that the variables move in opposite directions. Neutral correlation denotes that there is no relationship between the variables. Correlation is a technique that is used in statistics to identify the strength of the relationship between two variables. Correlation can be used to identify the strength of the linear relationship between two variables. Correlation measures the degree to which two variables vary together, in other words, it measures how much the variables are associated with one another. Correlation is used to identify the relationship between two variables. If there is a strong correlation between two variables, it indicates that there is a strong relationship between the variables. Correlation analysis helps in determining the strength and direction of the relationship between the variables. The correlation coefficient is used to measure the strength of the relationship. The correlation coefficient ranges from -1 to +1. The correlation coefficient of +1 indicates a perfect positive correlation, and the correlation coefficient of -1 indicates a perfect negative correlation. The correlation coefficient of 0 indicates that there is no correlation between the variables.

To understand how observational evidence is used to test the nebular theory.
Introduction. Our modern theory of the formation of our solar system, called the nebular theory, successfully explains all the major features of our solar system. In this tutorial, you will consider how this theory should apply to other solar systems.
Part A
Sort the following hypothetical discoveries into the appropriate bins as follows:
Consistent with theory: The statement describes a discovery that we could reasonably expect to find if the nebular theory is correct.
Not consistent with theory: The statement describes a discovery that would force us to modify or discard the nebular theory.
According to the nebular theory, the solar system was formed by the gravitational collapse of a giant molecular cloud, which eventually formed the sun and the planets. This theory has been widely accepted by astronomers as it explains several observed phenomena in the solar system, such as the similar orbital planes and the direction of rotation of the planets, and the composition of asteroids and comets.
However, there are some observations that would be inconsistent with the nebular theory, and that would require modifications or a complete rejection of the theory. One example of such an observation is the discovery of a planet orbiting a star in a retrograde direction.
According to the nebular theory, all planets should orbit their star in the same direction as the star's rotation, as the planets formed from the same spinning disk of gas and dust as the star. Therefore, the discovery of a planet with a retrograde orbit would require a modification of the nebular theory.Another example of an observation that is not consistent with the nebular theory is the presence of hot Jupiters, which are giant gas planets orbiting very close to their star.
According to the nebular theory, gas giants should form far from their star, where the temperature is low enough for ice to condense and form planetesimals. These planetesimals would then grow by accretion to form gas giants. However, hot Jupiters cannot form in the inner regions of a protoplanetary disk, as the temperatures are too high for ice to condense. Therefore, the presence of hot Jupiters requires a modification of the nebular theory.There are also other theories that could explain the formation of the solar system, such as the disk instability theory and the capture theory. These theories have their own strengths and weaknesses, and they are still being studied and debated by astronomers.

what is the shape, center, and variability of the total time required for the entire operation of positioning and attaching a randomly selected part?
For the entire operation of positioning and attaching a randomly selected part, there are no changes in the shape and variability of the total time distribution of the entire operation whereas the center of the normal distribution enlarges each operation performed.
We know that -
A time and motion study is used to determine the time needed by an assembly line worker to carry out different repetitive tasks.
For such an operation of positioning and attaching a randomly selected part, we can define shape, center, and variability as below -
(a) Shape -
For a randomly selected part of different repetitive tasks, there exists a normal distribution function.
So, if there are several repetitive task such as positioning and attaching are added up one after another, there is a certain constant being added up to every particular operation.
We know that, in a normal distribution function, any addition of constant doesn't affect the shape of the total time distribution. So, there won't be any change in the shape of the total time required for the entire operation.
(b) Center
We have already determined that the entire operation of positioning and attaching represents a normal distribution function where certain repetitive tasks equal to the addition of constant to this function.
So, for this type of normal distribution function, addition of constant to a specific operation (or, data value) will lead to increase in the center of normal distribution.
Thus, the center of the total time distribution will be magnified for the entire operation.
(c) Variability
For the normal distribution function that represents the entire operation of positioning and attaching a randomly selected part, there is always a constant being added to the distribution.
For each of the constant added to the operations (or, data value), there won't be any change in the variability of the normal distribution.
Therefore, for the entire operation of positioning and attaching a randomly selected part, there are no changes in the shape and variability of the total time distribution of the entire operation whereas the center the distribution enlarges each operation performed.

1. (100 points) Consider a utility function given by
u(ct)=ln(ct)+βln(ct+1) where β=1/1+rho
and the constraints are given by yt=ct+st
yt+1+(1+r)st=ct+1
(a) (10 points) Combine the two constraints by eliminating st
(b) (10 points) Solve the constraint for ct+1
(c) (10 points) Plug the constraint into ct+1 in the utility function.
(d) (20 points) Differentiate the utility function with respect to ct
(e) (20 points) Derive the Euler Equation.
(f) (20 points) What is the intuitive interpretation of the Euler Equation?
(g) (10 points) Suppose rho=0.05 and the real interest rate is 3%. Which is larger; ct ct+1? Why?
(a) The value of st from the second constraint into the first constraint is yt = ct + (ct+1 - ct) = 2ct + ct+1, (b) The constraint for ct+1 is yt - 2ct, (c) u(ct) = ln(ct) + βln(yt - 2ct), (d) u'(ct) = 1/ct - 2β/(yt - 2ct), (e) 1/ct = 2β/(yt - 2ct), (f) The intuitive interpretation of the Euler Equation is that it represents the optimal intertemporal consumption choice, (g) β = 0.9524.
(a) To combine the two constraints, we can substitute the value of st from the second constraint into the first constraint:
yt = ct + st
yt = ct + (ct+1 - ct) = 2ct + ct+1
(b) Solving the constraint for ct+1, we get:
yt = 2ct + ct+1
ct+1 = yt - 2ct
(c) Plugging the constraint into ct+1 in the utility function, we have:
u(ct) = ln(ct) + βln(yt - 2ct)
(d) Differentiating the utility function with respect to ct, we get:
u'(ct) = 1/ct - 2β/(yt - 2ct)
(e) To derive the Euler Equation, we set the derivative of the utility function with respect to ct equal to 0:
0 = 1/ct - 2β/(yt - 2ct)
Simplifying, we have:
1/ct = 2β/(yt - 2ct)
(f) The intuitive interpretation of the Euler Equation is that it represents the optimal intertemporal consumption choice. It states that the marginal benefit of consuming one additional unit today (1/ct) is equal to the discounted marginal benefit of consuming one additional unit tomorrow (2β/(yt - 2ct)).
(g) If rho=0.05 and the real interest rate is 3%, we can calculate the value of β:
β = 1/(1+rho)
= 1/(1+0.05)
= 0.9524
To determine whether ct or ct+1 is larger, we need more information.

A limo is rented at a fixed cost for an evening. It is rented by 12 people, the average cost for each person will be $2 less than if it is rented by 10 people. How much does the limo cost for the evening?
Answer:
$120
Step-by-step explanation:
According to the information in the statement and taking into account that the price for renting the limo is fixed, you can say that the cost of renting the limo for 12 people is equal to the cost of renting it for ten. Then, the cost for 12 people is 12 for the cost per person which is equal to 10 for the cost per person and you can express it as follow:
x is the cost per person when the limo is rented by 10 people.
12*(x-2)=10*x
You can solve for x:
12x-24=10x
12x-10x=24
2x=24
x=24/2
x=12
Now that you have the cost per person when the limo is rented by 10 people, you can multiply this value for 10 to find the cost of renting the limo for the evening:
12*10=120
The answer is that the limo cost $120 for the evening.
