Answer:
Independent event
Step-by-step explanation:
Independent event is defined as events that will not influence each other. In this question, the combination lock has three separate wheels. Each wheel has one key out of 10 possible numbers. The key of the first wheel will not influence the number pool of second and third wheels. All of the wheels will have 10 possible numbers regardless. Therefore, the combined number is an independent event.
Answer:
3/25
Step-by-step explanation:
Since it is stated that 12/25÷4
It can also be written as 12/25/4
Which means 12/25×1/4
So let's solve
3/25
The Reason why we get 3/25 is because 12 is being divided by 4
So the final answer to the given question is 3/25

Step-by-step explanation:
Answer:
B
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here the vertex = (- 2, - 3 ) , then
y = a(x - (- 2))² - 3 , that is
y = a(x + 2)² - 3
To find a, substitute any point on the graph into the equation
Using the coordinates of the y- intercept (0, 5 )
5 = a(0 + 2)² - 3 ( add 3 to both sides )
8 = a(2)² = 4a ( divide both sides by 4 )
2 = a
y = 2(x + 2)² - 3 → B
