For an in-class demonstration, a teacher flips a fair coin 5 times, and each of the 5 times it lands on heads. A student argues

that it's more likely to land on tails on the next flip. What, if anything, is incorrect about the student's logic?
A.
The student's logic is incorrect; since a coin being flipped 5 times is 5 independent events, the probability of the next flip landing on heads is still 1/2.
B.
The student's logic is incorrect; since a coin being flipped 5 times is 5 dependent events, the probability of the next flip landing on heads is still 1/2
C.
There is nothing wrong with the student's logic; because a coin being flipped 5 times is 5 independent events, the probability the next flip will land on heads is affected by the previous outcomes.
D.
There is nothing wrong with the student's logic; because a coin being flipped 5 times is 5 dependent events, the probability the next flip will land on heads is affected by the previous outcomes.

Roman55 [17]

Answer:

number of yellow marbles=62.

Step-by-step explanation:

It is given that in a bag there are yellow marbles and blue marbles and the total number of marbles=73.

Let the number of Blue marbles=x, then according to the question, number of yellow marbles will be =5x+7.

Now, Total number of marbles= number of yellow marbles+number of blue marbles.

⇒73=x+5x+7

⇒73-7=6x

⇒66=6x

⇒x=11

Therefore, numberof blue marbles=x=11 and

number of yellow marbles=5x+7=5(11)+7=55+7=62.

If $3,000,000 is invested at 6% interest compounded continuously, how much
g100num [7]

Answer:

  $24,498,509.74

Step-by-step explanation:

The formula for the value as a function of time is ...

  V(t) = P·e^(rt)

Filling in the numbers and doing the arithmetic, we have ...

  V(35) = 3,000,000·e^(0.06·35) ≈ 24,498,509.74

Compounded continuously for 35 years, the investment will be worth $24,498,509.74.

What’s the answer to f(a)
S_A_V [24]

Answer:

The answer to this is fa

Step-by-step explanation:

This is because you as the solver doesn't know what the variables f or a is so you put them together as multiplication until you do understand what f and a are so you can multiply them.

If you were to graph this it would be a horizontal line going infinite in both directions. That means no slope or y axis.
