Answer:

A good rule is to change 10 to 15 percent of the water each week. If your tank is heavily stocked, bump that up to 20 percent each week. A lightly stocked aquarium can maybe get by for two to four weeks, but this should be the maximum length of time between water changes.

Answer:

2/10

Step-by-step explanation:

If you are trying to find out the probability of a number just know that the whole number is always going to be the denominator. In this problem, the denominator is <em>10</em> because that is the whole number of pieces of paper.

Then we look at the second part of the problem where it is asking us to figure out the probability of pulling out a number that is less than 3 which would only leave us  with <em>1-2 </em>

This means that the probabilaty of pulling out a number less than 3 is <u><em>2/10</em></u>

(need some help!!) explain why the lowest possible domain value for a linear model of this data must begin at x = 6
ra1l [238]

Hello!

To first understand this question, we have to know what a domain is, and what it means to be linear.

The domain is all the possible x values.

Currently, in this graph, it starts at 0, and goes to some point further on.

To be linear means that you have linear growth, which this does not.  This has a bend in it, which is not linear.  

So, you must restrict the domain such that you only have a linear section.

If you look at the graph as a whole, it makes a bend. But, if you only look at x value 6 and up, it seems quite straight.

So, this makes sense!

Hope this helps, feel free to ask questions in comments.
