Teddy buys a new television that was orignally priced $399 and on sale for %15 off. How much money did he save? What was the new
1 answer:
Answer:
Teddy saved $
The new price of the tv is $
Step-by-step explanation:
To find out how much the new price of the tv is you need to do as follows:
We know that it was 15% off meaning it keeps 85% of its value. Knowing this we do
This gives us
To find out how much he saves, we find the difference:

Answer:
Step-by-step explanation:
Given that;
the following procedure for accomplishing our task are:
1. Flip the coin.
2. Flip the coin again.
From here will know that the coin is first flipped twice
3. If both flips land on heads or both land on tails, it implies that we return to step 1 to start again. this makes the flip to be insignificant since both flips land on heads or both land on tails
But if the outcomes of the two flip are different i.e they did not land on both heads or both did not land on tails , then we will consider such an outcome.
Let the probability of head = p
so P(head) = p
the probability of tail be = (1 - p)
This kind of probability follows a conditional distribution and the probability of getting heads is :
Thus; the probability of getting heads is which typically implies that the coin is fair
(b) Could we use a simpler procedure that continues to flip the coin until the last two flips are different and then lets the result be the outcome of the final flip?
For a fair coin (0<p<1) , it's certain that both heads and tails at the end of the flip.
The procedure that is talked about in (b) illustrates that the procedure gives head if and only if the first flip comes out tail with probability 1 - p.
Likewise , the procedure gives tail if and and only if the first flip comes out head with probability of p.
In essence, NO, procedure (b) does not give a fair coin flip outcome.
The above equation is applicable for each and every value of a,
So, Correct option is A. True
