Answer:
Slope = 1/8
Step-by-step explanation:
(20-18)/11- - 5)
= 2/16
= 1/8
Orthocenter is the point of concurrence of the altitudes of the triangle.
This means Orthcenter is the point where the altitudes intersect.
Here one altitude is x = -1
The other altitude is y = x + 1
Substituting x = -1 in y = x + 1
We get
y = -1-1=0
Hence the point of intersection of the altitudes is (-1,0)
The orthocenter of the triangle whose altitudes are x = -1 & y = x+1 is (-1,0)
(-1,0) which is Option c) or the third option is the right answer.

Answer:
Therefore the probability that 3 or more were involved in an accident last year is 0.376.
Step-by-step explanation:
Binomial distribution:
A discrete random variable X having the set {0,1,2.....,n} as the spectrum, is said to have binomial distribution with parameter n= the number of trial and p = probability of getting successes in one trial if the p.m.f of X is give by
for x=0,1,2,....,n
=0 elsewhere
where
, n is a positive integer and 0<p<1.
Given that,
7% of all drivers were involved in an accident last year that was determined by a car insurance company.
p= 7%=0.07, n=11, x=3
P(X≥3)
= 1-P(X≤2)
= 1- P(X=0)-P(X=1)-P(X=2)


=1-0.624
≈0.376
Therefore the probability that 3 or more were involved in an accident last year is 0.376.
