What is the solution to the system of equations y =- 3x 2 5x 2y 15?
Answers
The solution of the given system of equation is (-19, 55).
In the given question we have to find the solution to the system of equations:
y = -3x-2 and 5x + 2y = 15
We can solve the system of equation using the substitution method.
In substitution method we have to put the the value of one variable from one equation to the other equation.
We have to equations:
y = -3x-2...................................(1)
5x + 2y = 15.............................(2)
Now putting the value of y from the equation 1 in equation 2
5x + 2(-3x-2) = 15
Now solving the equation using the distribution method.
5x - 6x - 4 = 15
Simplifying
-x - 4 = 15
Add 4 on both side we get
-x = 19
Now the value of x is -19.
Now putting the value of x in equation 1
y = (-3)*(-19)-2
y = 57-2
y = 55
Hence, the solution of the given system of equation is (-19, 55).

There are 14 dogs in a particular class at a dog show. blue, red, yellow, and white ribbons will be awarded to the first through fourth place finishers, respectively. in how many different ways can the ribbons be awarded?
a. 1,001
b. 6,006
c. 24,024
d. 38,416
Answers
As per the combination method, the number of ways can the ribbons be awarded is 24,024
The general formula to calculate the combination is written as,
nCr = n!/r! (n - r)!
where n refers the set or population and r refers subset of n or sample set
Here we have given that there are 14 dogs in a particular class at a dog show. blue, red, yellow, and white ribbons will be awarded to the first through fourth place finishers,
Here we need to find the number of different ways can the ribbons be awarded.
While we looking into the given question, the following details are given in it,
Total number of dogs = 14
Number of ribbons = 5
Which means that the value on n = 14 and the value of r = 5.
As per the given question we know that,
There are 14 possibilities for blue one
And then there are 14 - 1 = 13 possibilities for red ribbon.
And for the next yellow one has 12 possibilities
Then the white one has 11 possibilities.
Therefore, the total number of ways is
=> 14 x 13 x 12 x 11
=> 24024
Therefore, option (c) is correct.

What is the nature of roots of 2x² 3x 5 0?
Answers
The nature of the roots of 2x² 3x 5 0 are imaginary, as it is not possible to solve for real numbers.
To solve this equation, we first factor out the coefficients (2 and 5). Factoring out 2 gives us x² + 1.5x + 5 = 0. After that, we solve for x using the quadratic formula:
x
= -1.5 ± √(-1.5² - 4(1)(5)) / 2(1). This is reduced to x = -1.5 9.5 / 2, an imaginary number that cannot be solved using real values. This indicates that the equation's roots are fictitious.

Answers
Population parameters are used to estimate sample statistics, and this is true.
Population parameters are used to describe the characteristics of a population, such as the mean, median, and standard deviation, and are used to make inferences about a population. Sample statistics, on the other hand, are used to describe the characteristics of a sample of a population. For example, a sample statistic could be the mean of a sample of people's heights.
To estimate sample statistics, population parameters must first be known. For example, the sample mean can be estimated using the population mean. If the population means are unknown, then the sample means can be estimated using the sample mean.
In conclusion, population parameters are used to estimate sample statistics, and this is true. Population parameters provide useful information about a population that can be used to make inferences about a sample. Knowing the population parameters allows researchers to make more accurate estimates of sample statistics, which in turn can be used to make more reliable inferences about a population.

How do you know if its discontinuous?
Answers
Discontinuity can be determined by looking for sudden changes in values or jumps in the graph of the function. If there is a break or gap in the graph, the function is discontinuous.
Discontinuity occurs when a function fails to be defined at a certain point within its domain, resulting in a sudden change in the graph of the function. Discontinuity can be determined by plotting the graph and looking for sudden changes in values or jumps in the graph. If the graph shows a break or gap, then the function is discontinuous. Discontinuity can also be determined by examining the behavior of the function at a certain point. If the function values diverge as the point is approached from either side, then the function is discontinuous at that point. Additionally, a function can be discontinuous at a point if it does not obey the rule of continuity, which is that the function's value must be equal to the limit of the function as the point is approached from both sides. If the limit does not exist at a point, then the function is discontinuous at that point.

Find the simple interest on $6000 from 16 may 2010 to 9 october 2010 at 10% per annum.
Answers
The simple interest is $6,240.00.
The term simple interest refers the interest that is only calculated on the initial sum borrowed or deposited.
Here we need to find the simple interest on $6000 from 16 may 2010 to 9 October 2010 at 10% per annum.
While we looking into the given question, we know te following values,
Principal amount = $6000
Time period = 16 may 2010 to 9 October 2010
The number of days between 16 may 2010 to 9 October 2010 is
=> 146 days.
Here we have the interest for 1 year,
So, the time period is written as,
And then we have to put time into years for simplicity,
146 days / 365 days/year = 0.4 years.
And the interest rate = 10%
Here we have to convert R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year.
Now, we have to apply the values on the formula, then we get by solving our equation:
A = 6000(1 + (0.1 × 0.4)) = 6240
A = $6,240.00
Therefore, the total amount accrued, principal plus interest, from simple interest on a principal of $6,000.00 at a rate of 10% per year for 0.4 years (146 days) is $6,240.00.

Answers
The median of 4 and 7 is 5.5.
The median is the middle point in a dataset—half of the data points are smaller than the median and half of the data points are larger.
The data set's median is the value in the center. Put all the numbers in ascending or descending order, and then choose the middle number to determine the median. There will only be one middle integer if the number of data points is odd. If the number of data points is even, you must choose the middle two numbers, add them together, and divide by two. Your median will be that value.
The mean of these middle values is (4+7)/2 = 11/2= 5.5

In other words, if the lengths of the sides of two triangles are the same, then the triangles must be the same shape and size.
For example, consider two triangles ABC and DEF. If we know that
AB = DE, BC = EF, and AC = DF,we can use the SSS theorem to conclude that triangle ABC is congruent to triangle DEF.
It is important to note that the SSS theorem is only applicable if the three sides of each triangle are equal in length. If the sides are not equal, the theorem does not apply and we cannot use it to prove the congruence of the triangles.

In substitution method we have to put the the value of one variable from one equation to the other equation.
We have to equations:
y = -4x + 10...................................(1)
y = -2x - 6.............................(2)
Now putting the value of y from the equation 1 in equation 2
-4x + 10 = -2x - 6
Add 6 on both side we get
-4x + 16 = -2x
Add 4x on both side, we get
2x = 16
Divide by 2 on both side, we get
x = 8
Now the value of x is 8.
Now putting the value of x in equation 1

Answers
The total distance traveled by the cows are 3.58 meters. To calculate that we need to calculate fourth area before.
It sounds like you are trying to solve a problem involving two cows grazing in a field and the area that they graze. Here is a possible solution:
First, draw a diagram to represent the situation. Let O be the point where the rope is fixed, and let A and B be the points where Gauri moves between. Similarly, let C and D be the points where Bindiya moves between. Draw the lines connecting these points to form four sides of a quadrilateral.Next, measure the lengths of the sides of the quadrilateral. Since the total area of the quadrilateral is 10 square meters, and the length of the rope is 12 cm.We can use the formula for the area of a quadrilateral to solve for the fourth side:
Area = (1/2) x (12 cm) x (fourth side)
Solving for the fourth side, we get:
Fourth side = (20 cm)/(12 cm) = 1.67 meters
Finally, add up the lengths of the four sides to find the total distance traveled by the cows:
Total distance = (1.67 meters) + (12 cm) + (1.67 meters) + (12 cm) = 3.58 meters
