Among 120 visitors to Disneyland, 74 stayed for at least 3 hours, 86 spent at least $20, 64 went on the Mat-terhorn ride, 60 stayed for at least 3 hours and spent atleast $20, 52 stayed for at least 3 hours and went on theMatterhorn ride, 54 spent at least $20 and went on theMatterhorn ride, and 48 stayed for at least 3 hours, spentat least $20, and went on the Matterhorn ride. Drawing aVenn diagram with three circles (like that of Figure 4) andfilling in the numbers associated with the various regions,find how many of the 120 visitors to Disneyland(a) stayed for at least 3 hours, spent at least $20, but didnot go on the Matterhorn ride;(b) went on the Matterhorn ride, but stayed less than 3hours and spent less than $20;(c) stayed less than 3 hours, spent at least $20, but did notgo on the Matterhorn ride.
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.
terhorn ride, 60 stayed for at least 3 hours and spent atleast $20, 52 stayed for at least 3 hours and went on the
Matterhorn ride, 54 spent at least $20 and went on the
Matterhorn ride, and 48 stayed for at least 3 hours, spent
at least $20, and went on the Matterhorn ride. Drawing a
Venn diagram with three circles (like that of Figure 4) and
filling in the numbers associated with the various regions,
find how many of the 120 visitors to Disneyland
(a) stayed for at least 3 hours, spent at least $20, but did
not go on the Matterhorn ride;
(b) went on the Matterhorn ride, but stayed less than 3
hours and spent less than $20;
(c) stayed less than 3 hours, spent at least $20, but did not
go on the Matterhorn ride.
