The probability that demand is greater than 1800 gallons over a 2 hour period is : 0.5
<u>Given data :</u>
Mean value of gasoline per hour = 875 gallons
Standard deviation = 55 gallons
<h3>Determine the probability of demand being greater than 1800 gallons over 2 hours </h3>
Demand for gas in 1 hour = X₁
Demand for gas in 2 hours = X₁ + X₂
Therefore ; ( X₁ + X₂) ~ N ( u₁+u₂, sd₁² + sd₂² )
In order to calculate probabilities for normals apply the equation below
Z = ( X- u ) / sd
where : u = 1800, sd = √ ( 55² + 55² ) = 77.78
using the z-table
P( Y > 1800) = P( Z > ( 1800 - 1800 ) / 77.78)
= P( Z>0 ) = 0.5
Hence we can conclude that The probability that demand is greater than 1800 gallons over a 2 hour period is : 0.5.

Answer:
i) $21 billion
ii) $0
iii) $0
Explanation:
GIVEN DATA : ( two countries )
At the end of year 2
net exports = $20 billion for Japan
Interest earned from assets = $1 billion for Japan
i) The balances for the current account for Japan
export value + interest earned from assets
= $20 billion + $1 billion = $21 billion
ii) Financial account for Japan
Financial account for Japan will be zero because there is no increase or decrease in number of its assets within the given period
iii) capital account for Japan
Capital account of Japan will will have a zero balance. this is because Capital account is used to record foreign investments, local investment and the reserve account as well. and there was no investment captured within the given time that was made by Japan
Answer:
$367,500
Explanation:
Estimation of the family’s life insurance needs
Using the easy method
Based on the information given we were told that Mark gross salary is $75,000 while is wife
Parveen is a stay-at-home mom this means that we would be using the easy method to estimate the family’s life insurance needs based on Mark gross salary of $75,000 because he is the only one that earn on a monthly basis.
Insurance need =$75,000 x 7 years x 70%
Insurance need = $367,500
Therefore the family’s life insurance needs will be $367,500
Answer: a. Computer-aided manufacturing
Explanation: A computer-aided manufacturing would help the robot manufacturing company in this regard since it can provide the required software to control the machine tools and processes needed in the manufacture of the multi-utility robots.
Computer-aided manufacturing (CAM) is defined as the use of software and computer-controlled machinery to automate a manufacturing process and is composed entirely of software that tells a machine how to make a product through the generation of toolpaths; a machinery that can turn raw material into a finished product and a post processing unit that converts toolpaths into machine languages. Computer-aided manufacturing thus provides high–speed machine tool paths that greatly minimize cycle times, reduce tool and machine wear and general improvement in quality and accuracy of cutting.
Individuals, corporations, and economies specialize because the opportunity cost of producing goods and services differs from country to country, business to business, and individual to individual.
Persons, Corporations, and Economies are bound to specialize in the production of goods and or services in which they hold a stronger comparative advantage than their competition.
<h3>What is comparative advantage?</h3>
This is defined as the ability of an individual, corporate entity, or national to perform an economic activity more efficiently or at a lower (opportunity cost) than the other.
Examples of economic activities are:
- Resource management
- production of services and goods
- distribution of services and goods
- consumption of services and goods
