Answer:
There will be 3472 cats in 10 years
Step-by-step explanation:
There were 3500 cats
The number of dogs in a city is declining at a rate of about 0.08% each year.
We are supposed to find the no. of cats in 10 years
Formula :
Where N(t) = Remaining cats after t days
= Initial population
r = rate of depreciation
t=time
So, No. of cats remained after 10 years =
Hence There will be 3472 cats in 10 years
The standard deviation of quiz scores is 0.
<h3>What is the standard deviation?</h3>- The standard deviation in statistics is a measure of the amount of variation or dispersion in a set of values.
- A low standard deviation indicates that the values of the set tend to be close to the mean (also known as the expected value), whereas a high standard deviation indicates that the values are spread out over a larger range.
To find the standard deviation:
- Let, the number of students = n
- x = 100
- Mean = n×x/n=x
- Variance =
- Variance = (x₁ - x)² + (x₂ - x)² + (x₃ - x)²/n
- V = 0
- Standard variance = √0
Therefore, the standard deviation of quiz scores is 0.
