Answer:
D
Step-by-step explanation:
Two events are said to be independent if the occurence of one event does not affect the occurence of the other.
Note:
A. there sum cannot be equal to 1
B. Mutually exclusive events are events with posibility of happening at thesame time
C. When intersection is zero, it means the set is empty, because intersection of an empty set is equal to an empty set
Thus, option D feels most appropriate
First collect the like terms together= -228+-189+384
then work out=-228+-189+384
=-417+384
=-33
the answer is -33

For this case we have the following multiplication:
We can rewrite this operation to facilitate the calculation.
We have then:
From here, we apply the distributive property.
We have then:
Rewriting we have:
Finally adding all the numbers we have:
Answer:
The value of 6 * 298 is 1788 and the calculations can be provided as follows:
Answer:
(-1, 4)
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
10x + 6y = 14
-x - 6y = -23
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Add 2 equations together: 9x = -9
- Divide 9 on both sides: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: -x - 6y = -23
- Substitute in <em>x</em>: -(-1) - 6y = -23
- Multiply: 1 - 6y = -23
- Subtract 1 on both sides: -6y = -24
- Divide -6 on both sides: y = 4
