Answer:
16%
Step-by-step explanation:
Given the total number of students in a school = 675
Number of students at a squirrel during flu season = 108
Squirrels are known for transmitting flu disease, therefore if 108 students are at the squirrels during a particular day, there is possibility that this ones have contacted flu.
Percentage of those that have flu = number of students at the squirrels/Total number of students × 100%
= 108/675 × 100
= 10800/675
= 16%
This means that 16% of the students have flu
Answer:
For a flag with 2 different colours, there are 8 possible colours for the first colour to be chosen from and 7 possible colours (excluding the first colour already chosen) for the second colour to be chosen from, given that colours are different. Hence there are a total of 8 x 7 = 56 possible flags to be created.
Step-by-step explanation:
When a finite number of samples are drawn from a larger population, the sample mean of that sample, while usually close to the population mean, is not the same thing. A population mean, on the other hand, is a description of pretty much ALL of whatever is being examined.
Example of population: Everyone in the USA
Example of a sample: One person, chosen at random, from each of the 50 states
