<u>Answer:</u>
The equation is y = 2x - 5
<u>Solution:</u>
Here, x= 3; y= 1
We know the slope of an equation is given by y = mx+c
The value of m which is equal to 3 is given in the question.
Putting the value of m in the slope intercept form we get,
y = 2x+c
To find the The value of c, we substitute the value of x and y from any two given point. Lets take x = 3 and y = 1
Therefore, the slope intercept equation becomes y = 2x - 5
Answer:
0.405 or 40.5%
Step-by-step explanation:
Let event A=having a periodontal disease
event B=having a heart attack
we are given
P(A)=P(having a periodontal disease)=0.30
P(B)=P(having a heart attack)=0.15
P(A/B)=P(have a periodontal disease/have a heart attack)=0.81
P(B/A)=P(have a heart attack/have a periodontal disease)=?
P(A/B)=P(A∩B)/P(B)
P(A∩B)=P(B)*P(A/B)=0.15*0.81=0.1215
P(B/A)=P(A∩B)/P(A)=0.1215/0.3=0.405
There is 40.5% probability that if someone has periodontal disease will have a heart attack.
Answer:
Each one of the ten people has to shake hands with all the $20$ other people they don’t know. So $10\cdot20 = 200$. From there, we calculate how many handshakes occurred between the people who don’t know each other. This is simply counting how many ways to choose two people to shake hands from $10$, or $\binom{10}{2} = 45$. Thus the answer is $200 + 45 = \boxed{\textbf{(B)}\ 245}$.

Answer:
dunno
Step-by-step explanation:
Slope is (y2-y1)/(x2-x1)
(10-4)/(7-5)
6/2 = 3
The slope is 3
