So first you need to see how much the numbers are going up in each time. From 6 to 11, it's going up 5, and from 11 to 16, it's going up 5, which means the first part of the expression will be 5n. Now, imagine the 5 multiplication table alongside the sequence, and see how to get from those values to the current values. So, from 5 to 6 you add 1, and from 10 to 11 you also add 1. This means your final answer is
5n + 1. I hope this helps!

The bar chart shows the percent of times each color marble was drawn from a bag after 1000 draws with replacement after each dra
DiKsa [7]

Answer:

Following are the solution to this question:

Step-by-step explanation:

In this question, the graph file is missing so, its solution can be defined as follows:

When the bag includes 20 marbles, each will be drawn 5% of the time on average.  

The bar chart shows that nearly 50% of the workforce red marbles are drawn, and about 25% of the time blue and white marbles are drawn. so, the equation is:

\to \frac{50\%}{5\%}= \frac{50 \times 100}{5\times 100}=\frac{50}{5} = 10 \ red \ marbles\\\\\to \frac{25\%}{5\%}= \frac{25 \times 100}{5\times 100}=\frac{25}{5} = 5\  blue \ marbles

\to 5 white marbles are available in the bag.
