Answer: $140
Step-by-step explanation:
1/4 × 560 to buy a coat
= 0 25 x 560 = $140
Remaining balance after purchase of coat will be $560 - $140 = $420
Next, he uses 2/3 of $420 for present
2/3 × 420
0.667 x 420
= $280 for present
Alice's balance will be remaining balance after purchase of coat - money for present
= $420 - $280
=$140

Answer:
Pr(opposite face is tail) = 1/4. = Option (a)
Step-by-step explanation:
From the illustration,
=> 1st coin has head both side
=> 2nd coin has tail both side
=> 3rd coin has head and tail.
If we toss a coin at random and head comes up; it implies that it can never have been the 2nd coin.
Consequently, we are left with only two coins (the 1st and the 3rd coin). Now, total number of coin that remain in the sample = 2.
Meanwhile,
=> the probability of tail from the 1st coin is ZERO
=> the probability of tail from the 3rd coin is 1/2.
Therefore, the probability of opposite face is tail is:
Pr(opposite face is tail) = (0+ 1/2)/2 = 1/4
Answer:
x = 10
Step-by-step explanation:
2 (x - 5) = 10
2x - 10 = 10
2x = 10 + 10
2x = 20
x = 20/2
x = 10
The solution to this system is the line x + y = 5. Since the first
equation states that the quantity of (x+y) is greater than or equal to
5, while the second states that the same quantity of (x+y) is lesser
than or equal to 5, therefore the greater and less than parts are
contradictory, and the only possibly solution is that x + y = 5.
