Answer:
A. P(EC) = 0.4
B. P(E∪E) = 0.75
C. P(EC ∩ FC) = 0.25
Step-by-step explanation:
Let us calculate -:
we are given with - P(E) = 60 and P(F) =.15,
Thus , (a)
(b) P(E∪F) = P(E) + P(F)
= 0.60 + 0.15
= 0.75
(c) ∩
∪
=
Hence , the answers are -A. P(EC) = 0.4 , B. P(E∪E) = 0.75 , C. P(EC ∩ FC) = 0.25.
Step-by-step explanation: Here, we're asked to reflect ΔQRS over
the x-axis so we begin by reflecting point Q over the x-axis.
Since point Q is 2 units below the x-axis, point Q will reflect
over the x-axis to a position 2 units above the x-axis.
We label this point as Q' which is the ordered pair (1, 2).
Next we reflect point R over the x-axis.
Since point R is 2 units below the x-axis, point R will reflect
over the x-axis to a position 2 units above the x-axis.
We label this point as R' which is the ordered pair (3, 2).
Now connect the points to get our reflection.
Next we reflect point S over the x-axis.
Since point S is 6 units below the x-axis, point S will reflect
over the x-axis to a position 6 units above the x-axis.
We label this point as S' which is the ordered pair (1, 6).
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
we know that
The solution of the inequality is the shaded area above the solid line
The slope of the solid line is negative m=-2/3
The x-intercept of the solid line is (3,0) (value of x when the value of y is equal to zero)
The y-intercept of the solid line is (0,2) (value of y when the value of x is equal to zero)
using a graphing tool
see the attached figure
The solution is the shaded area
