Answer: 0.22hz
Step-by-step explanation:
Hi to answer this question we have to analyze the information given:
- <em>Period (T) = 4.5 Seconds
</em>
So, to calculate the frequency of the pendulum we have to apply the formula;
Frequency (f)= 1 / period
Replacing with the value given:
f = 1/ 4.5 sec = 0.22 hz

Answer:
The probability of selecting a red or green marble is 0.6923.
Step-by-step explanation:
Let's denote the events as follows:
<em>R</em> = a red marble is chosen
<em>G</em> = a green marble is chosen
The information provided is:
n (R) = 7
n (G) = 5
n (R ∩ G) = 3
Total number of marbles in the bag is, N = 13.
The probability of an event <em>E</em> is:
Compute the probability of selecting a red or green marble as follows:
P (R ∪ G) = P (R) + P (G) - P (R ∩ G)
Thus, the probability of selecting a red or green marble is 0.6923.
