What is the slope of a line parallel to the line whose equation is y - x = 5?
2 answers:
Answer:
Slope of new line is 1.
Step-by-step explanation:
We know that,
The general equation of a line is , where m = slope and b = y-intercept.
Now, the equation of the given line is,
On comparing, the slope of the given line is 1.
<em>Since, 'The slopes of two parallel line is always equal'.</em>
<h3>Thus, the line parallel to the given line is also 1.</h3>You might be interested in
Answer:
a) P(2)=0.270
b) P(X>3)=0.605
c) P=0.410
Step-by-step explanation:
We know that customers arrive at a grocery store at an average of 2.1 per minute. We use the Poisson distribution:
a) In this case:
Therefore, the probability is P(2)=0.270.
b) In this case:
Therefore, the probability is P(X>3)=0.605.
c) We know that two customers came in in the first minute. That is why we calculate the probability of at least 5 customers entering the other 2 minutes.
In this case:
Therefore, the probability is P=0.410.
