Answer:
4
Step-by-step explanation:
He should add 4 black blocks because there are a total of 4 other blocks, and in order to have a probability of 50%, the number of black blocks needs to be equal to the total number of the other colored blocks.
I think is the 3rd sorry if I’m wrong
Answer:
2 inches
Step-by-step explanation:
Snail C moves 1 inch every 15 mins. Since half an hour is 30 mins, 30 / 15 = 2.
15 mins + 15 mins = there for your answer is 2 inches in half an hour.
<span>Let t
= travel time at 58</span>
<span>and
(6-t) = travel time at 49
distance at 58 + distance at 49 = 325.5 mi</span>
<span>
58t + 49(6-t) = 325.5
58t + 294 - 49t = 325.5</span>
9t+294
= 325.5
9t
=31.5
T =
31.5/9 = 3.5 hours at 58 mph
6-3.5
= 2.5 hours at 49 mph
<span> Check:</span>
58*3.5
= 203
49*2.5=
122.5
203+122.5
= 325.5
The geometric distribution applies to experiments employing Bernoulli trials (success or failure) to determine the number of trials to obtain the first success.
This distribution may be applied to the given situation, where the probability of success is p.
Let n=number of transmissions required (n ≥ 1)Then
P(n)=(1-p)^(n-1)*p (probability that n transmissions are required)
and the mean number of transmissions required
μ = 1/p
