<span>-2x+3=5
Subtract 3 from both sides
-2x=2
Divide both sides by -2 so that the only thing remaining on one side is the variable x
Final Answer: x= -1</span>
Answer:
Yes, it is possible if the sweaters on sale are $7.40 each.
Step-by-step explanation:
The sweaters each cost $37. To purchase all four (for herself and 3 sisters) without a sale would be 4(37)= $148.
40% off the regular price would be 0.40(148)= $59.20 savings. She would spend 148-59.2= $88.80.
Is it possible to buy two regular price sweaters and two on sale for $88.80?
2(37)=$74. If we subtract from the sales total, 88.80-74=14.80. This means the two sweaters on sale must each be $7.40. It is possible to save 40%.
Answer:
75
Step-by-step explanation:
1 - P(no tails)
1 - (½)²
1 - ¼
¾ × 100 = 75%
Answer:
60.6%
0.0003%
Step-by-step explanation:
Because they are independent events, the final probability will be the multiplication of each event, that is, 0.92 multiplied 6 times, in other words:
0.92 ^ 6 = 0.606
that is to say that the probability that the 6 men survive is 60.6%
Now, to calculate that at least one survives, it means that 5 died, the probability that one dies is 1 - 0.92 = 0.08, and how they are 5 would be:
0.08 ^ 5 = 0.0000032768
Then multiplied by 0.92, which is that one survives, we are left with:
0.0000032768 * 0.92 = 0.00000301465
Which means that the probability of one surviving is 0.0003%, it is a very low probability because the probability of surviving is really high.
