A warehouse with a value of $200,000 is insured for $140,000 under an 80% coinsurance policy. A fire loss of $80,000 occurs. How much of the loss will the insurance company pay for? PLEASE SHOW WORK
The amount of loss that the insurance company will pay is $70000
How do you calculate coinsurance and deductibles?Deductible plus the amount of coinsurance equals the out-of-pocket maximum.
Determine the $1,000 deductible that the insured is required to pay.
Calculate the coinsurance payment due from the insured: 20% of $5,000 equals $1,000.
What is the formula for coinsurance?The coinsurance penalty is calculated using the straightforward formula: the loss multiplied by the amount of insurance that should have been in place, less any deductible, equals the amount that was actually paid.
The following covered losses are subject to the coinsurance provision: Property value: $200,000; policy limit: $140,000; coinsurance: 80%; loss: $100,000; deductible: $250; all other numbers: $200,000; etc.
The insured only had $140,000 when they should have had $160,000 (200,000 x.80).
The coverage will cover the deductible plus $87,500. (140,000/160,000
=.875; $100,000 x .875
= $87,500; $87,500 - $250

How to do graph representation?
Graph representation is a way of visualizing data as a graph or chart. It is used to easily identify relationships between data points and to illustrate trends in the data. Graphs can be used to present data in a variety of ways, such as bar graphs, line graphs, pie charts, scatter plots and more. Graphs are especially useful when trying to compare two or more sets of data and to highlight any patterns or trends that may exist. Additionally, graphs are often used to represent numerical data in a more visually appealing way. By using graphs, it is easier to identify relationships, trends and outliers in the data. Graphs also help to make data easier to interpret and understand.

Answer:
10.5
Step-by-step explanation:
These numbers are off by a little more than one power of ten:
[tex]1.2\times 10^6 \rightarrow 1.26 \times 10^7[/tex]
[tex]10^7 \div 10^6 = 10[/tex] ← one power of ten
[tex]1.26 \div 1.2 = 1.05[/tex] ← a little more

Best subset regression is an exploratory model building regression analysis. It compares all possible models that can be created based upon an identified set of predictors.
The goal of attribute subset selection is to find a minimum set of attributes such that dropping of those irrelevant attributes does not much affect the utility of data and the cost of data analysis could be reduced. Mining on a reduced data set also makes the discovers pattern easier to understand.

The probability that the product of the numbers on the top faces of all four dice is a prime number is [tex]\frac{1}{108}[/tex] .
We have given that,
six-sided dice are rolled 4 times
i.e. probability of this event is [tex]6^{4}[/tex] = 1296.
The condition is product of the numbers on the top faces of all four dice is a prime number.
The only way to get a prime number by multiplication is to have three of the numbers equal to one and the fourth number equal a prime.
The prime less than 6 are 2,3,5.
Each prime number will come on the all four dices top faces.
Therefore outcomes are,
{1,1,1,2}, {1,1,2,1, {1,2,1,1}, {2,1,1,1}, {1,1,1,3}, {1,1,3,1}, {1,3,1,1}, {3,1,1,1}, {1,1,1,5}, {1,1,5,1}, {1,5,1,1}, {5,1,1,1}.

The population of a city decreases by 3.3% per year. If this year's population is 72,000, what will next year's population be, to the nearest individual?
Using the given information, the city's next year population will be 69,840
Determining the population of a cityFrom the question, we are to determine what the population of the city will be the following year
From the given information,
"The population of a city decreases by 3.3% per year"
and
This year's population is 72,000
Thus,
The population of the following year will be
72000 - 3% of 72000
Next year population = 72000 - 3% of 72000
Next year population = 72000 - 3% × 72000
Next year population = 72000 - 0.03 × 72000
Next year population = 72000 - 2160
Next year population = 69,840

Simplify
Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
Power
In mathematical relationships, power is referred to the number of times a number is multiplied by itself meaning the number you get raising a number to an exponent whereas an exponent can be defined as the number of times the number is used in a multiplication. Exponents are often known as powers or indices.
Exponents
Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner. For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as 34, where 4 is the exponent and 3 is the base. The whole expression 34 is said to be power.
Rewrite [tex]i^{100}[/tex] as [tex](i^{4} )^{25}[/tex]
One to any power is one.

From the fact that [tex]i^{2}[/tex] = −1,

Step-by-step explanation:
8 numbers summed and divided by 8 = 41
8numberssummed / 8 = 41
8numberssummed = 41 * 8 = 328
now taking out two numbers whose mean is 29 is the same as taking out two 29's from the sum ....so now there are SIX numbers
6numberssummed = 8numberssummed - 29 -29
= 328 -29 -29 = 270
so to find the mean of the remaining six numbers:
6numberssummed / 6 is 270/6 = 45
Answer:
mean = 45
Step-by-step explanation:
mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
given the mean of 8 numbers is 41 , then
[tex]\frac{sum_{8} }{8}[/tex] = 41 ( multiply both sides by 8 )
sum₈ = 328
given the mean of 2 of the numbers is 29 , then
[tex]\frac{sum_{2} }{2}[/tex] = 29 ( multiply both sides by 2 )
sum₂ = 58
Then
sum₆ = sum₈ - sum₂ = 328 - 58 = 270
then the mean of the other six numbers is
mean = [tex]\frac{sum_{6} }{6}[/tex] = [tex]\frac{270}{6}[/tex] = 45

Step-by-step explanation:
We can solve this a super simple way.
The midpoint is (-6,-3/2) and the coordinate B is (-1,3)
We notice that we change y by positive 5 and we change our x by negative 3/2, from M to B. So to get to A from M, we change y by -5 and change our x by positive 3/2...
So we have:
(-6-5,-3/2+3/2)

Find the best predicted value of ModifyingAbove y with caret given that the twin born first has an IQ of 104? Use a significance level of 0.05.
The best-predicted value of Modifying Above y with caret given that the twin born first has an IQ of 104 is 106.2.
The dependent variable's predicted value in basic linear regression is given by the equation = b0 + b1x.
In order to minimize the total sum of squared errors, the values of b0 and b1 are derived from the data using the equation line = b0 + b1X. (the error is the difference between the predicted value and the actual value of y).
Use regression equation
ŷ=14.68+0.88x
