Answer:
48.3 cm²
Step-by-step explanation:
Let A be the area of the yellow region
A= the area of the square - the area of the quarter square
A= 15²-(15²*π)/4= 48.28≈ 48.3 cm²

Answer:
Step-by-step explanation:
Given: a graph
To find: the average rate of change of the amount of the element over the 10-minute experiment
Solution:
A rate of change of one quantity with respect to another quantity is known as rate of change. If y is the dependent variable and x is the independent variable then average rate of change = change in y /change in x.
From the graph,
change in x (time) = minutes
change in y ( amount of the element) = g
So, average rate of change =
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.
