Answer: 11.2x -9.6
Step-by-step explanation:
7.2(x + 3) + 4(x - 3) - 12 - 7.2* (x + 3) + + 4*(x - 3) then
7.2x + 21.6 + 4x - 12 - Combining like terms 7.2x+ 4x and numbers + 21.6- 12
7.2x + 4x +21.6 -12 Then we have
11.2x -9.6
Y=5-2x
x^2 + (5-2x)^2 = 25
x^2 + 25-20x+4x^2 = 25
x^2 +4x^2-20x+25=25
5x^2 -20x=0
x=0 and y=5

Answer:

Step-by-step explanation:
The experimental probability can be defined as the ratio of the number of times any particular event has occurred to the total number of times that event has taken place.
Experimental probability = P = No. of event occurrences / total number of occurrences.
In our question statement,
No of naturally occurring triplets are = 3375
Total number of births = 5 million = 5,000,000
Putting values in equation.
