The table you drew under the question is exactly the right way to start.
-- Make a second column, next to the 6 and 7. This column will be
the actual number of each thing.
-- You know that there are 42 marbles, so write '42' in the box
next to the 6, on the 'Marbles' line.
Now you need to figure out what to write in the 'Stones' line, next to the 7.
-- Look at the 'Marbles' line. There's a 6 and then a 42.
Ask yourself: " Self ! What does the 6 have to be multiplied with to get 42 ?"
-- Whatever the answer is, drop down to the 'Stones' line,
and multiply the 7 by the same number.
The product is the total number of stones, and it goes in the box.

(The mystery number is 7. There are 49 stones.)
Answer: 138
Step-by-step explanation:
Answer: Choice A) An economic theory that is shared by the discipline of Psychology
Through the research I've found so far, the articles mention that economic choices have a psychological link. This is because economics is basically the study of human psychology (more or less) in terms of how to allocate resources and how best to use them. The law of diminishing marginal utility is basically the idea where the concept "more is always better" is simply not true. An example would be that you are at a restaurant and there's an endless buffet. The food isn't infinite and neither is the capacity of your stomach. After a certain point, you'll find that eating another burger isn't as satisfying as eating the first few burgers. You can think of it as a graph where the curve may start with a sharp increase, but eventually it levels off.
Side note: The term "affective habituation" may be used in psychology textbooks as something very similar to the law of diminishing marginal utility.
Explanation
Part A
We can use the formula below to find the mean.
We will then have;
Mean = 6.2632
Part B
Since the data set is odd.
Answer: From the column of cumulative frequency cf, the median is 7
That is true because factors of 40 are 10,5
