Answer: Option 'B' is correct.
Step-by-step explanation:
Since we have given that
P(A) = 0.5
P(B) = 0.5
P(C) = 0.15
P(D) = 0.7
P(E) = 0.15
We need to find the independent events.
When we consider,
P(A∩D) = P(Event A and Event D) = 0.35
and
P(A) × P(D) = 0.7 × 0.5 = 0.35
We get that
P(A∩D)= P(A) × P(D) = 0.35
All other options are not satisfying the conditions of "Independent events".
Hence, Option 'B' is correct.
Linear combination method just means to add the equations so that one variable with cancel. In this case the a values are already set up so that they will cancel.
2a + 3b = 1
-2a + b = 11
4b = 12
b = 3
now put 3 back into either of the original equations and solve for a.
2a + 3(3) = 1
2a + 9 = 1
2a = -8
a = -4
(-4,3)
<h3><u>
Answer:</u></h3>
- The equation is y = -x/2 - 3
<h3><u>
Step-by-step explanation:</u></h3>
<u>We know the equation.</u>
<u>We also know the y-intercept, which is -3.</u>
<u>All we need to find is the slope. Once the slope is found, our equation is set.</u>
- => Slope = Rise/Run
- => -1/2 = Slope
<h3><u>Conclusion:</u></h3>
<u>Since the slope has been found, </u><u>the equation is y = -x/2 - 3.</u>
Hoped this helped.
The three angles of a triangle always add to 180, do the 2 congruent angles must measure 180-120=60. this number must be divided in two since the angles are congruent, so 60/2=30.
[email protected], as needed. so the equation to find x, the size of the congruent angles, would be
x=(180-120)/2
