The township of Middleton sets the speed limit on its roads by conducting a traffic study and determining the speed (to the nearest 5 miles per hour) at which 80% of the drivers travel at or below. A study was done on Brown's Dock Road that indicated drivers' speeds follow a normal distribution with a mean of 36.25 miles per hour and a variance of 6.25. Fill in Multiple Blanks Do calculations in Excel. Do not round intermediate calculations. Round your final answer to the required precision. You can use the "Format Cells..." option in Excel to show the required number of decimal places (Excel will automatically round the number up or down). What should the speed limit (to the nearest 5 miles per hour) be? Blank 1 In your answer, show the whole number. Do not show any digits to the right of the decimal point. Apply the appropriate rounding rule if necessary. What percent of the drivers travel below the speed limit you indicated in part (a)? Blank 2 In your answer, show one (1) digit to the right of the decimal point, for example, 1.0, 1.2. Apply the appropriate rounding rule if necessary. Do not show the % sign.
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.
