(x-h)^2+(y-k)^2=r^2
r=radius
(x-3)^2+(y+4)^2=14
(x-3)^2+(y+4)^2=(√14)^2
answer is 2nd option
r=√14
A right angled triangle is a traingle with equal sides and the same size angles acute angles are normally in iscoceles triangle and are less than 90 degrees obtuse normally can be on a line or in a scalene triangle it’s more than 90 degrees but no more than 180 degrees
Answer: About 99.7% of the population wait between 5 minutes and 35 minutes.
Step-by-step explanation:
According to the Empirical rule,
If a population is normally distributed, then
About 99.7% of the population lies within 3 standard deviations from the mean.
Here, Population is normally distributed with Mean = 20 minutes , standard deviation = 5 minutes
By empirical rule,
About 99.7% of the population wait between (20-3(5)) minutes and (20+3(5)) minutes.
About 99.7% of the population wait between 5 minutes and 35 minutes.
