Answer:
The number of minutes in a month must be equal to 50 minutes
Step-by-step explanation:
Let
x ---> the number of minutes
we have
<em>Cost Plan A</em>
<em>Cost Plan B</em>
we know that
In order for plan A cost the same than plan B, the following equation must hold true.
cost of plan A = cost of plan B
substitute
solve for x
therefore
The number of minutes in a month must be equal to 50 minutes

The time taken by the first and the second train is 1 hour 40 minutes and 1 hour 25 minutes. Then the time when the second train at Niles junction is 5:55 p.m.
<h3>What is speed?</h3>The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
A train leaves Thorn junction at 1:25 p.m. and arrives in Niles at 3:05 p.m. the train makes two stops along the route for a total of 15 minutes.
A second train leaves Thorn junction at 4:30 p.m. and heads to Niles.
This train does not make any stops.
Let the speed of both trains be equal.
Then the time taken by the first train will be
t₁ = 3:05 p.m. - 1:25 p.m.
t₁ = 1 hour 40 minutes
Then the time taken by the second train will be
t₂ = 1:40 - 00:15
t₂ = 1:25 = 1 hour 25 minutes
The time when the second train is at Niles junction will be
→ 4:30 p.m. + 1:25
→ 5:55 p.m.

Answer:
The outlier on the the scatter plot is point L(6,2).
Step-by-step explanation:
M(3,3)
P(5,5)
N(5,7)
L(6,2)
Other points are : (1,3), (2,3), (2,4), (3,4), (3,5), (4,5), (4,6), (5,6)
Now, To find the outliers on the scatter plot we plot all the given points on the graph.
The resultant graph is attached below :
An outlier is a value in a data set that is very different from the other values. That is, outliers are values which are usually far from the middle.
As we can see the graph the point L(6,2) is the most unusual or the farthest point on the scatter plot as compared with all the other points on the scatter plot.
Hence, The outlier on the the scatter plot is point L(6,2).
