Answer:
Step-by-step explanation:
The equation of a circle has the following format:
In which r is the radius(half the diameter) and the centre is the point
Centered at the origin
This means that
Passing through the point(0,10)
The radius is the distance of any point in which the circle passes to the centre.
Using the formula for the distance between two points.
So
Answer:
Step-by-step explanation:
Given that taxi Fares are normally distributed with a mean fare of $22.27 and a standard deviation of $2.20.
For a random single taxi std deviation is 2.20
But for a sample of size 10, std deviation would be
This would be less than the 2.20
Because std devition is less for sample we get a big z score for the sample than the single.
As positive values of z increase we find that probability would decrease since normal curve is bell shaped.
So single taxi fare would have higher probability than sample.
B) Here >24.
By the same argument we have z value less for single taxi hence the probability for more than that would be less than that of sample size 10
