Hello!
What is the exact circumference of the circle?
A.
10π feet
B.
20π feet
C.
40π feet
D.
60π feet
Solving: Using the data (Circle with center A and diameter of 20 feet labeled).
diameter = 2*radius
Formula: (Circle length)
Now, replace in the circumference length formula:
Answer:
B. 20π feet

To determine the probability that both people chosen are females, we will use the rule of multiplication.
Let event A = the event that the first person chosen is female; and let B = the event that the second person is female.
To start, it is given that there are 10 students, 5 of them are females. Therefore, P(A) = 5/10
After the first selection, there are 9 students, 4 of them are females. Therefore, P(A|B) = 4/9
Based on the rule of multiplication:
P(A∩B) = P(A) * P(A|B)
P(A∩B) = (5/10) (4/9)
P(A∩B) = 20/90
P(A∩B) = 2/9
The probability that both people chosen are females is 2/9.
In general, the probability of a disjunction is
In this case, A and B are mutually exclusive, so 
This simplifies the formula to
Check the graph and observe where x = 2.
And check where it cuts across the line of the graph.
If you trace the graph carefully, when x = 2, y = -2
So the value of the function is -2.
I hope this helps.
A.)
Z = kx/y where k is a constant.
32 = 16k/4
k = 128/16
k = 8
z = 8x/y
b.)
Z = 8(21)/6
Z = 28
c.)
4 = 8x/48
x = 192/8
x = 24
