What is the chance that a person randomly selected off the street was born in May

Mathematics

EastWind [94]3 years ago
8 0

Answer: Eight percent.

Step-by-step explanation: In order to find this, we have to use the probability formula, which is:

The Event We Are Looking For/All of the Events.

In this case, plugging the numbers into the formula we get

May(1)/All the months in the year, including May (12).

Diving this, our answer will be 0.08333..., or rounded up to 0.8

However, since we are only looking for one specific event, we can take the number 100, and divide it by all the events. 12/100 is 8.333..., or rounded to 8.

Write the equation of a circle with center (6,4) that passes through the coordinate (2,1). In your final answer, include all of
Elodia [21]
All points along the circle with be the distance of the radius from the center...so the radius can be found using the Pythagorean Theorem..

r^2=(4-1)^2+(6-2)^2

r^2=9+16

r^2=25

r=5

The equation of the circle can be expressed as:

r^2=(x-h)^2+(y-k)^2 where (h,k) correspond to the center of the circle, (2,1) in this case.

(x-2)^2+(y-1)^2=25

if you wanted it in a more standard form...

(y-1)^2=25-(x-2)^2

(y-1)^2=25-x^2+4x-4

(y-1)^2=-x^2+4x+21

y-1=(-x^2+4x+21)^(1/2)

y=1(+/-)(-x^2+4x+21)^(1/2)
