Before 1918, approximately 60% of the wolves in a region were male, and 40% were female. However, cattled rachers in the area have made a determined effort to exterminate wolves. From 1918 present, approximately 65% of the wolves in the region are male, and 35% are female. Biologists suspect that male wolves are more likely than female to return to the area where the population have been greatly reduced. Round three decimals: a) Before 1918, in a ramdon sample 11 wolves spotted in the region, what is the probability that 8 or more were males? - what is the probability 8 or more were females? - what is the probability fewer than 5 were females? d) From the period 1918 to present in a ramdon sample 11wolves spotted in the region, what is the probability that 8 or more were males? -what is the probability 8 or more were females? -what is the probability fewer than 5 were females?
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.
