When 6.25% is compounded quarterly to get $18,000 in 13 years, the total amount is $22,478.16 in compound interest.

Divide the total by the yield curve, the length of time, and other factors to arrive the simple interest. Simple return = money + return + hours is the marketing formula. This method allows it easiest to calculating interest. The most typical technique to figure approximately interest is as a portion of the principal sum. He will only pay his share of the 100% extra, for example, if he borrows $100 from a neighbor and agrees to pay it back with 5% interest. $100 (0.05) = $5. When you borrow, you must pay interest, and when you give it out, you must charge interest. Interest is often determined like an indicator of the overall of both the loan total.

given

Amount = Principal (1 + rate of interest) number of years

= $1,200 (1 + 0.032) 8

= $1,200 1.286582318

= $22,478.16 is the amount in compound interest.

The remaining amount is $40,478.16.

Answer:

Step-by-step explanation:

A) The equation for the perimeter of a rectangle is given by 2 * (length + width), so we can write the equation for this rectangle as:

2 * (30 + w) = 108

B) To find the width of the rectangle, we can solve for w:

60 + 2w = 108

2w = 48

w = 24

So, the width of the rectangle is 24 cm.

The function f(x) is linear and equation is y = 4x + 6 where x=0,1,2,3,4

A function is defined as a relationship between a group of inputs that each have one output. A function is a connection between inputs in which each input is associated to exactly one output. Every function has a domain and a co-domain, as well as a range. In general, a function is denoted as f(x), where x represents the input. A function's generic representation is y = f(x).

In mathematics, there are several types of functions. Some examples include:

When there is a mapping for a range for each domain between two sets, this is referred to be an injective function or a one to one function.

Surjective functions, also known as Onto functions, are used when more than one element is transferred from domain to range.

Polynomial function: A function made up of polynomials.

Inverse Functions: A function that may be used to inverse another function.

Now,

For function f(x)=6,10,14,18,22, g(x)=8,10,12,16,22 for x=0,1,2,3,4

f is a function because y increases 4 for each increase of 1 in x

slope = 4

intercept = f(0) =6

Hence Equation is y = 4x + 6 where x=0,1,2,3,4

The limit of the sum (6xi-3)/n as n approaches infinity is 9, which means that as the number of subintervals in the interval [0,3] becomes larger and larger, the sum of the values (6xi-3)/n approaches 9.

The limit is a concept in mathematics that helps us understand what happens as a function or a sequence approaches a certain value.

In this particular problem, we are looking at the limit of a sum of values as the number of subintervals in the interval [0,3] approaches infinity.

The interval [0,3] is divided into n equal subintervals and a number xi is chosen arbitrarily in the ith subinterval. We then look at the sum of the values (6xi-3)/n for all n subintervals.

Mathematically, we can write this sum as:

S = (6xi-3)/n for i = 1, 2, ..., n

And the limit of S as n approaches infinity can be written as:

lim n -> infinity S = lim n -> infinity (6xi-3)/n

Now, we use the concept of a Riemann Sum to evaluate the limit of this sum. A Riemann Sum is a way of approximating the area under a curve by breaking it down into rectangles and summing their areas.

In our case, we can think of the sum S as a Riemann Sum for the function f(x) = 6x-3 over the interval [0,3]. As n approaches infinity, the width of the subintervals approaches 0, and the sum S approaches the definite integral of f(x) over [0,3].

Using the fundamental theorem of calculus, we can find the definite integral of f(x) over [0,3] as:

∫f(x)dx = 6x^2/2 - 3x evaluated from 0 to 3

And this value is 9, so the limit of S as n approaches infinity is 9.

Answer:

Step-by-step explanation:

Find the probability that X is less than 92:

We can use the cumulative distribution function (CDF) of a normal distribution to find the probability that X is less than 92. The CDF of a normal distribution with mean μ and standard deviation σ is given by:

F(x) = (1/2) * [1 + erf((x-μ)/(σ * sqrt(2)))]

Where erf is the error function.

So, the probability that X is less than 92 can be calculated as:

P(X < 92) = F(92) = (1/2) * [1 + erf((92-108)/(17 * sqrt(2)))]

This value can be calculated using a calculator or statistical software.

Find the probability that X is between 92 and 126:

We can use the CDF to find the probability that X is between 92 and 126. The probability that X is between 92 and 126 is equal to the difference between the CDF values at 126 and 92:

P(92 < X < 126) = F(126) - F(92)

This value can also be calculated using a calculator or statistical software.

Find the IQ of an individual that is in the top 10% of the population:

To find the IQ of an individual that is in the top 10% of the population, we need to find the value of X that corresponds to a cumulative probability of 0.9. This can be done by solving for X in the CDF equation:

F(X) = 0.9

X = μ + σ * inverse_CDF(0.9)

Where inverse_CDF is the inverse cumulative distribution function and can be calculated using a calculator or statistical software. The value of X that corresponds to a cumulative probability of 0.9 is the IQ of an individual that is in the top 10% of the population.
