If a coin is flipped three times in a row, what is the probability of getting tails on all three flips?

1 answer:

4 0

Probability of getting tails on first flip = 1/2

Probability of getting tails on second flip = 1/2

Probability of getting tails on third flip = 1/2

Probability of getting all 3 tails = 1/2 * 1/2 * 1/2 = 1/8

Suppose that you have a bowl of 500 m&m candies, and each day you eat 1/4 of the candies you have. Is the number of candies

Aleks [24]

Answer:

$500(.75)^{n}$

Step-by-step explanation:

It is changing exponentially because if you are eating a fraction of the left over m & m's, that is a different amount each time so it can't be linear.

500(1-(1/4))^n

$500(.75)^{n}$

A firecracker shoots up from a hill 145 feet high with an initial speed of 80 feet per second. Using the formula H(t) = -16t2 +

kiruha [24]

145 = -16 t² + 80 t +s
s = ?
v = v0 - at
0 = 80 - at
80 = at
s = 80 t - at²/2
s = 80 t - 80t/2
s = 40 t
Finally: 145 = -16 t² + 80 t + 40 t
16 t² - 120 t + 145 = 0
We will solve this quadratic equation:
t = [120 +√ ( (-120)²- 4 · 16 · 145 )] / 32
t = [120 + √ (14400 - 9280) ] / 32
t = (120 + 71.55) / 32 = 5.98 ≈ 6 s
Answer:D) 6 seconds
