<em>Write the equation of a line perpendicular to y=-12x+2 going </em>
<em> through (0, -1)</em>
<em />
<em> </em>
First, let's take a look at our provided information:-
- A line
- A point (0, -1)
- The line
is perpendicular to the line that goes through (0, -1)
If two lines are perpendicular to each other, their slopes are opposite reciprocals of each other.
So we take the slope of the given line, which is -12, change its sign from minus to plus:-
And now, We flip the number over:-
Now that we've found the slope of the line, let's find its equation.
The first step is to write it in point-slope form as follows:-
Replace letters with numbers,

Answer:
a)P=0.42
b)
Step-by-step explanation:
We have a binomial distribution, since the result of each experiment admits only two categories (success and failure) and the value of both possibilities is constant in all experiments. The probability of getting k successes in n trials is given by:
a) we have k=2, n=10 and p=0.01:
b) We have, , Here P is the probability that at least one particle will penetrate the shield, this probabity has to be equal or greater than 0.95. Therefore, this will be equal to subtract from the total probability, the probability that the particles do not penetrate raised to the total number of particles.
