what is the simple interest on 30000 naira for 4 years at 8% rate
Answer:
Step-by-step explanation:
- Hint: In this question we asked to find the Simple interest. Here, we will calculate simple interest for 4 years at 8% per annum by using the formula of simple interest (SI) =PRN100 .
Complete step-by-step solution -
To find the simple interest first we will know about simple interest.
Simple interest is based on principal amount for a fixed period of time. The amount which we deposit or take loan from the bank is known as principal amount. The period of time for which the money is lent is known as time on interest.
Now, we will calculate here simple interest,
SI =PRN100
Where P (principal amount) = Rs. 3000
R (Rate of interest) = 8%
N (number of period) = 4 years
So, finding simple interest by putting all the value, we get
=3000×8×4100
=30×8×4
=960 Rs.
our tendency to believe we can predict the outcome of random events is the ____________.
A person's tendency to believe he/she can predict the outcome of random events is known as the Hindsight bias
What are outcomes and events in math?An event is the total number of results from a random experiment. Trial results are the outcome. The outcome of an event is the totality of all potential outcomes. To better understand this, let's use an example. Example: Chances of rolling a die and getting the desired number
What are the three types of outcomes?The three types of outcomes are Organizational outcomes, Team outcomes, and Personal or Individual outcomes.
A psychological phenomenon called hindsight bias enables people to persuade themselves after an occurrence that they correctly predicted it before it occurred. People may get the conclusion that they can foresee subsequent occurrences with accuracy as a result.

simple interest on a $198,562 mortgage at 3.99%?
The simple interest on the amount $198,562 mortgage at 3.99% will be $7922.62.
What is simple interest?Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific duration of time.
Unlike compound interest, which adds the interest from the principal of prior years to determine the interest of the following year, the principal amount in simple interest remains constant.
As per the given,
Principle amount P = $198,562
Rate = 3.99%
Interest amount = 3.99% of $198,562
⇒ (3.99/100)198562 = $7922.62
Hence "The simple interest on the amount of $198,562 mortgage at 3.99% will be $7922.62".

What are the Permutation and Combination?
Permutations and combinations are the various ways in which objects from a set can be selected to form subsets, generally without replacement. When the order of selection is a factor, this selection of subsets is called a permutation; when it is not, it is called a combination.
Consider each team playing with the other team once

The equation for the line of best fit to predict the salary for an employee with 6 years of experience is $58,587.
What is meant by slope?The letter m is frequently used to represent slope; the reason for this is unclear, although it is first used in English by O'Brien in 1844, who wrote the equation for a straight line as "y = mx + b," and by Todhunter in 1888, who wrote it as "y = mx + c."
Finding the ratio of "vertical change" to "horizontal change" between any two unique locations on a line yields the slope. When the ratio is stated as a quotient ("rise over run"), the result is the same for each
We have to take any two points in the given information and find the value of slope.
Let the two points are (0, 52000), (1, 53,150)
m=(53150-52000)/(1-0)
m=1150
Therefore, slope=1150
Now, the equation of the line is y=mx+b
52000=1150(0)+c
c=52000
Therefore, y=1150x+52000
For 6 years experience,
Take x=6 then,
y=1150(6)+52000
y=6900+5200
y=58,900
y=$58,900≈58,587

The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given information in the question,
Let me be n inches tall, while my sister is m inches tall.
I'm my sister's tallest by over $2 inches.
So, the equation obtained is,
n = 2 + m (1)
However, if we treble her height, it would be more than 51 inches taller than I am.
So, the equation will be,
3m = 51 + 2n (2)
We need to find the value of m.
In the equation, n should be replaced with the aforementioned value (2)

The Excel file Automobile Options provides data on options ordered together for a particular model of automobile. By examining the correlation matrix, suggest some associations.
You must count the instances of each rule and the instances of each item in each rule separately using the data in the Excel file in order to determine the support, confidence, and lift of a rule.
Open the Excel file and look for the information on the options ordered for the specific model of car. This information will probably be presented as a table or a group of columns, where each row represents a distinct order and each column a different choice.
You must count the instances of the rule's components occurring together in the data in order to calculate the support for a rule. You would need to track how frequently the fastest engine choice and the traction control option are selected together, for instance, if the rule is "If the quickest engine, then traction control." This can be accomplished by counting the number of cells in a range that satisfy a specific condition using Excel's COUNTIF function.
The confidence in a rule is calculated by dividing the total number of times the items in the premise (the "if" component of the rule) occur by the total number of times the items in the rule. The number of times the fastest engine and traction control options are selected together must be divided by the total number of times the fastest engine option is ordered, for instance, if the rule is "If the fastest engine, then traction control."
You must divide the rule's confidence by the support of the item in the rule's conclusion to determine the lift of a rule (the "then" part of the rule). You would need to divide the rule's confidence by the support for the traction control option, for instance, if the rule is "If the quickest engine, then traction control."
To calculate the support, confidence, and lift for each of the rules, you can use the Excel formulas indicated above together with any other Excel functions or tools you are familiar with.
It is crucial to keep in mind that the precise formulas and processes you will need to follow will depend on the exact data and rules you are working with, so you might need to modify the following instructions to suit your personal needs.

If the data is distributed normally, a z test can be used to determine whether the means of two populations differ from one another. The z test statistic's value must be determined, together with the null hypothesis and alternative hypothesis setups, for this reason. On the z critical value, the decision criterion is based. The distribution graph is divided into acceptance and rejection zones during hypothesis testing by the z critical value. The null hypothesis can be rejected if the test statistic lies inside the rejection region; otherwise, it cannot.

First, subtract 3 from both sides of the equation:
2x + 3 = 17
2x + 3 (-3) = 17 (-3)
2x = 17 - 3
2x = 14

b) Find the probability the next eruption occurs between 25 and 50 years. (6 points) (Round your answer to 4 decimal places)
(a) The probability that there will be exactly 3 eruptions in the next 200 years is 0.1404
(b) The probability the next eruption occurs between 25 and 50 years is 0.2488
Let X be the random variable denoting the volcanic eruptions as follows
Poisson distribution with parameters λ.
the average of the eruption is λ=2.5 per year.
Also for 200 eruptions the average of the eruptions is λ=2.5 per year.
Also, for 200 eruptions, the average of the eruptions is λ=5 per year.
The probability is:
P(X=3) = e⁻³(5)³/3!
= 0.0067×125/3×2×1
= 0.8422/6
= 0.1404
(b) Let X be the random variable denoting the volcanic eruptions as follows
Poisson distribution with parameters λ and also let 2.5 eruptions in 100 years is same as waiting time of:
100/2.5
= 40 years per eruption
therefore, X ~ Exp(β=40)
the probability density function of X is:
f(x) = { 1/40 e⁻¹/⁴⁰ , x>0
0 , otherwise}
And cumulative distribution function is:
P(X≤x) = 1 - e, x>0
the probability is:
P(25<X<50) = P(X<50)-P(X<25)
P(25<X<50) = e²⁵/⁴⁰ - e⁵⁰/⁴⁰
= e⁻°·°²⁵ - e⁻¹·²⁵
