Answer:
0.75
Step-by-step explanation:
Given that there is a 50% chance that it will rain today and a 50% chance that it will rain tomorrow
We find that these two events are independent
A = rains today and B = rains tomorrow
A and B are independent
So we have
P(AB) =P(A)P(B)
the probability that it rains at least one of the days
= P(A or B) =P(A)+P(B)-P(AB)
=0.5+0.5-0.5(0.5)
=0.75

what can i help u with
Step-by-step explanation:
The graph of x = |y| is as shown in the figure.
When we draw a vertical line, it intersects the graph at two points.
This means for the same value of x , we have two values of y.
Or in other words, for the same pre image, we have two images.
Hence it is not a function.
But for every value of x, we do have a value of y, hence it is a relation.
x = |y| is a relation but it is not a function
Answer:
x = - 2
Step-by-step explanation:
y = 4 is the equation of a horizontal line parallel to the x- axis.
Thus a perpendicular line will be vertical and parallel to the y- axis.
The equation of a vertical line is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (- 2, 1) with x- coordinate - 2, thus
x = - 2 ← equation of perpendicular line
