Answer:
231cm²
Step-by-step explanation:
find the area of the rectangle. 12 x 11=132
find the area of the triangle. 9 x 11=99
add the two areas together. 99 + 132=231
9x-y = 45
Move 9x to the other side. Sign changes from +9x to -9x.
9x-9x-y=45-9x
-y=45-9x
Multiply both sides by -1
(-1)(-y)=y
(-1)(45)=-45
(-1)(-9x)
y=-45+9x or y=9x-45
Answer: y=-45+9x or y=9x-45
Answer:
P(A|B) = 0.30
Step-by-step explanation:
P(A) = 0.30
P(B) = 0.60
To Find:
P(A|B) = ?
P(A|B) means probability of occurring of event A when event B has occurred.
P(A|B) = P(A∩B)/P(B)
We know that for independent events;
P(A∩B) = P(A).P(B)
So, we have:
P(A|B) = P(A).P(B)/P(B)
P(A|B) = P(A)
So, probability of occurrence of an independent event does not depend on the probability of a different event.
Answer:
E
Step-by-step explanation:
The equation of proportion is
y = kx ← k is the constant of proportionality and
k = 
Substitute the values from the table into the equation for k, that is
k =
