Greater than 50:
2 x (8 + 20 - 12 / 8) is 52
Less than 10:
2 x (8 +(20 - 12)) ÷ 6 is 5.33
Given probabilities P(A) AND P(B) are independent, the probability that both events to occur is given by:
P(A)∩P(B)
thus from the example, independent events will be:
P(blue)=70%, P(green)=30%, P(blue and green)=21%
Because:
P(blue)∩P(green)=0.7×0.3=0.21=21%
Answer:
x=0 or x=−5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x^2+15x=0
Step 2: Factor left side of equation.
3x(x+5)=0
Step 3: Set factors equal to 0.
3x=0 or x+5=0
x=0 or x=−5
Perimeter = 72m
length = x
width = x - 4
P = 2l + 2w
72 = 2x + 2(x - 4)
72 = 2x + 2x - 8
72 = 4x - 8
72 + 8 = 4x
80 = 4x
80/4 = x
x = 20
Therefore, the length = 20m and width = 16m
