A doctor works at a hospital estimate when to leave for work from his apartment; he decided to measure how long it takes him to go to the hospital every day. For one week, he records the time it gets him to drive from his apartment to the hospital, including searching for parking and reaching to his office. The data are as follows: M Eighty-one Min T Fifty-four Min W Seventy Min R Fifty-two Min F Forty-three Min 1- Will you recognize these times as a sample or a population? and way 2- Obtain the mean and the standard deviation for the time it requires him to go to his office at the hospital. 3- Lets say his roommate, who is working with him at the same hospital and same office, takes the train to the hospital. She records the time it takes her to get to the office during the exact week and was that her mean was Sixty-two minutes, and the standard deviation was Five. Based on these measurements, it is convenient to drive or ride the train to the hospital? and why.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
