Two events are independent if whether an event occurs or not doesn't affect the possibility of whether the other event occurs or not.
<span>"A bag contains red marbles and blue marbles. A red marble is selected followed by a blue marble, at random, without replacement": Since the selection is without replacement, the events are dependent.
"</span><span>A coin is flipped twice": Independent
</span>
<span>"A bag contains nickels and dimes. A nickel is selected followed by a dime, at random, with replacement.": Since the selection is with replacement, the events are independent.
</span><span>"A spinner contains 4 equal sectors. Each sector is labeled A, B, C, and D. The spinner is spun twice.": Independent</span>
Answer:
Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:
--- Twice as much Alice means 2 times Alice's earnings
--- 2 less than her friend
Required
Determine the total amount
Substitute for A in
Substitute for F in
The total amount is calculated by adding the earnings of Alice, her friend and you
<em>Hence, the total earnings is 5d - 2</em>
<u>Statement </u> <u>Reason</u>
<u> </u> Given
Subtract 9 from both the sides
<u></u><u> </u> Subtracting same number will not affect equation
Simplification
Multiplying by 5 both the sides
x= 10 By simplifying both the sides
Thus we solved the equation and got x =10 as answer.
Answer:
Step-by-step explanation:
Total distance to a temple = 2 miles
