Hello, there!
There are 365 days in a year.
We already know that one person has a birthday on blank day. We will call this person a. That means that there is a 100% chance that they have that birthday.
Because there are 365 days in a year, the odds of person b having a birthday on a certain day is 1/365
Odds of person A having that birthday: 365/365
Odds of person B having that birthday: 1/365
To find the odds of them having the same birthday, we must multiply these odds.
365/365 * 1/365 = 1/365
1/365 = 0.27%
This means that there is a 0.27% chance that both people share the same birthday.
I hope I helped!
Let me know if you need anything else!

-x + 5y = 4 ⇔ slope 1/5, y-intercept 4/5
5y - x = 15 ⇔ slope: 1/5, y-intercept: 3
2y - 3x = 7 ⇔ slope: 3/2, y-intercept: 7/2
2y = 5x + 7 ⇔ slope: 5/2, y-intercept: 7/2
<u>Explanation</u>
-x + 5y = 4
5y = x + 4
y = (1/5)x + 4/5 slope 1/5, y-intercept 4/5
5y - x = 15
5y = x + 15
y = (1/5)x + 3 slope: 1/5, y-intercept: 3
2y - 3x = 7
2y = 3x + 7
y = (3/2)x + 7/2 slope: 3/2, y-intercept: 7/2
2y = 5x + 7
y = (5/2)x + 7/2 slope: 5/2, y-intercept: 7/2

Answer:
x = 3
Step-by-step explanation:
Tangents to a circle from the same point are the same length.
43 -2x = 12x +1
42 = 14x . . . . . . . add 2x-1
3 = x . . . . . . . divide by 14
It is.
2(x+3)=2x +6
Times 2
2x + 6 =2x+6

Answer:
After division we get the value 4.29310344828
Step-by-step explanation:
let x =1,743 ÷406
x= 1,743 ÷406
we get
x=4.29310344828
