Is sequence a set?

In contrast to a set, the same items might appear more than once in a sequence at various points, and unlike a set, the order is important. A sequence can be described formally as a function from natural numbers (the positions of the sequence's elements) to the items at each of those positions.

A sequence is a list of elements that has been arranged in a certain way. For instance, the sequence 3, 7, 11, 15,... is a sequence because it follows a pattern where each term is created by adding 4 to the term before it.

If$2500was invested 6 years ago, andtheinterestwascompoundedquar-terly,whatwastheinterestrateifthecurrentvalueis$3425?

Answers

Answer:

The interest rate was 5.24%.

Step-by-step explanation:

You can use the following formula to calculate the interest rate:

i=n*((A/P)^1/nt-1), where:

i= interest rate

n= number of times interest is compounded= 4

A=value of investment= 3425

P= principal= 2500

t=time= 6

Now, you can replace the values on the formula:

i=4*((3425/2500)^1/4*6-1)

i=4*(1.37^1/24-1)

i=4*0.0131

i=0.0524

According to this, the answer is that the interest rate was 5.24%.

What meant by mathematical expression ?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

An expression that uses numbers, variables, or both is a mathematical expression. The equal symbol is never used in expressions. Here are a few phrases as examples. A mathematical statement stating the equality of two expressions is known as an equation.

Given,

5 boys tell yes and total boys and girls tell yes is 30 by simplifying

no of girls tell yes =30 - 5= 25

no of girls tell no =20

overall total boys tell no = 15-5=10

The no of boys tell no =10

So total no of boys and girls tell no = 20+10=30

total no of girls tell yes and no =60-15=45

Solve the system
x+2y=-11
3y=x+1

Answers

Answer:

x=-13, y=-4

Step-by-step explanation:

Answer: x=-7    y=-2

Step-by-step explanation:

x+2y=-11

3y=x+1

x=-2y-11    (1)

3y=x+1      (2)

Substitute the value of x of equation (1) into equation (2):

3y=-2y-11+1

3y=-2y-10

3y+2y=-2y-10+2y

5y=-10

Divide both parts of the equation by 5:

y=-2

Substitute the value of y=-2 into equation (1):

x=-2(-2)-11

x=4-11

x=-7

Thus, (-7,-2)

What is fraction multiply?

Multiplying fractions is defined as the product of a fraction with a fraction or with an integer or with the variables. The procedure to multiply the fractions are: Multiply the numerator with numerator. Multiply the denominator with the denominator. Simplify the fractions, if required.

Given:

Total coins : 549 coins

one third(1/3) of the coins are £1 coins

164 of the coins are 50p coins

rest of the coins are 20p coins

one third of 549 = 549/3 = 183

Thus ,  

£1 coins = 183

50p coins =  164

20p coins = 549 - (183 + 164) = 202

value of the 549 coins in pounds (£) is given by

[tex]= 549 * \frac{1}{3} * 1 + 164* 0.5 + (549 *\frac{2}{3} - 164)*0.2\\\\= 183 + 82 +40.4\\\\= 305.4[/tex]

What is the median of 50?

Answers

The median of the first 50 whole numbers is 24.5.

The midway value in a given set of figures or data is referred to as the median. To get the average value for a given group of integers, three distinct metrics are employed in mathematics.

Non-negative numbers, which can be expressed without fractions, are known as whole numbers.

The first fifty whole numbers are 0,1,2,3,4,5................49

The number of terms in the data, n=50.

Let [tex]n^{th}[/tex] term be denoted by [tex]t_{n}[/tex]

As the number of terms is even, thus the median will be [tex]\frac{t_{\frac{n}{2} } +t_{\frac{n}{2} }+1}{2}[/tex]

Substitute n with 50.

Median = [tex]\frac{t_{\frac{50}{2} } +t_{\frac{50}{2} }+1}{2}= t_{25}+t_{26} /2[/tex]

The 25th term of the sequence is 24.

The 26th term of the sequence is 25.

Thus, median = 24+25/2 = 49/2 = 24.5

a number has three distinct digits, the sum of the digits equals the products of the digits. how many three digit numbers satisfy this condition?

Answers

Only one three digits number 111 would satisfy this condition.

Let the three digits be x, y and z. Since the sum of the digits is equal to the product of the digits, we can write x + y + z = xyz

Simplifying the equation, we get x + y + z - xyz = 0

This is a quadratic equation in the form ax2 + bx + c = 0 where a = 1, b = 1 and c = -xyz

To solve this equation, we use the quadratic formula: x = [-b ± √(b2 - 4ac)]/2a

In this case, x = [-1 ± √(1 - (-4 * 1 * (-xyz))]/2

Since xyz must be a positive integer, the only solution is when the square root of 1 - (-4 * -xyz) is 0

This means xyz must be 1, so x + y + z = 1 + y + z = 3

Since x, y and z are all distinct digits, the only possible solution is when x = 1, y = 1 and z = 1, giving the solution 111.

In the given question we have to explain how we can solve for x and y using substitution.

In the Substitution method we find the value of one variable in term of other variable from the one equation then we put the value of that variable in other equation. After putting the value of that variable in other equation, equation converts into the similar variable. Then after solving we can easily find the value of one variable. After finding the value of one variable we put the value of that variable in first equation. By this we can find the value of both variable.

The average degree of variability in the dataset is represented by the standard deviation. It reveals the average deviation of each statistic from the mean.

Explain the term standard deviation?

Empirical principle

If your frequency distribution follows a normal distribution, the standard deviation and mean combined might help you determine where the majority of the values are located.

The 68-95-99.7 rule, often known as the empirical rule, reveals your values to you:

Nearly 68% of scores are within one deviation of the mean, nearly 95% are within two standard deviations, and nearly 99.7% are within three standard deviations.

Thus, the standard deviation is a less trustworthy indicator of variability for non-normal distributions and should be combined with other metrics like range or interquartile range.

The number of servings that can be made from 3 / 4 cups, the number of cups of flour needed for 10 servings is 1/4 cups.

Given :

First the number of servings that can be made per cup :

= Number of servings / Number of cups

= 30 / 3/4

= 30 * 4 / 3

= 120 / 3

= 40 servings

To get 10 servings therefore, you would need:

Why is it called linear function?

Answers

A linear function is a type of function that can be expressed in the form of a linear equation with one or more variables.

The equation is written as y = mx + b, where m is the slope and b is the y-intercept. The slope is the rate at which the line rises or falls and the y-intercept is the point where the line crosses the y-axis. The slope and y-intercept of a linear function are constants, meaning that the line does not curve or change direction. This is why it is called a linear function.

When calculating linear functions, the equation is used to identify the slope and the y-intercept. The slope and y-intercept are then used to plot the points on a graph. A linear equation has the form y = mx + b, where m is the slope and b is the y-intercept. The slope indicates the rate of change of the function and the y-intercept indicates the point where the line crosses the y-axis. To find the slope of a linear function, the equation is solved for m, which is the rise over run. To find the y-intercept, the equation is solved for b, which is the y-value when x = 0. Once the slope and y-intercept are determined, the points can be plotted on a graph and the linear equation can be written.

In summary, a linear function is a type of function that can be expressed in the form of a linear equation. The equation of the linear function is used to identify the slope and y-intercept, which are then used to plot the points on a graph. Linear functions can be used to model many real-world situations and to solve for x and y values for any given point.
