Answer:
Step-by-step explanation:
Since, the radius of the balloon 4 days ago = 5,
⇒
Now, if the radius is decreased by 0.5 cm each day,
Then the current radius of the balloon = 5 - 4 × 0.5 = 5 - 2 = 3 cm,
⇒
Thus, the ratio of the current volume of the balloon to the volume of the balloon 4 days ago
⇒ Option A is correct.
168,356 = 170,000
168,356 rounded to the nearest 10th thousand is 170,000 you are changing the 2nd digit, (thousand digit).
Answer:
The probability of 4 or fewer unsuccessful plates in one hour is 0.00752.
Step-by-step explanation:
Let <em>X</em> = number of plates that are unsuccessful.
The expected number of unsuccessful plates per hour is, <em>λ</em> = 12.
The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 12.
The probability function of a Poisson distribution is:
Compute the probability of 4 or fewer unsuccessful plates in one hour as follows:
P (X ≤ 4) = P (X = 0) + P (X = 1) + P (X = 2) + P (X = 3) + P (X = 4)
Thus, the probability of 4 or fewer unsuccessful plates in one hour is 0.00752.
