Vika [28.1K]

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.

What is 5a(-3b)(2a^2b^3) simplified?
Anna007 [38]

Simplifying 5a(-3b)(2a^2b^3) we get =-30a^3b^4

Step-by-step explanation:

We need to simplify 5a(-3b)(2a^2b^3)

Basically, we need to find the product of all terms.

Finding product:

Using exponent rule: a^b(a^c)=a^{b+c}

5a(-3b)(2a^2b^3)

=-15ab(2a^2b^3)

=-30a^3b^4

So, simplifying 5a(-3b)(2a^2b^3) we get =-30a^3b^4
