Explain the relationship between the number of painters and sculptors enrolled in the art schools.
1 answer:
The scatter plot shows that there is a positive association or relationship between the number of painters and sculptors enrolled in the art school. This is also known as a positive correlation.
As shown in the attached image, the <em>y-values </em><em>(Number of Painters) </em>change in the same direction as the <em>x-values </em><em>(number of Sculptors). </em>In other words, the number of painters increases as the number of sculptors increase.
<h3>What is a Scatter Plot</h3>A scatter plot is also known as a scatter chart, a scatter graph or scattergram is a type of mathematical diagram which uses Cartesian coordinates to show the relationship between two variables in a given data set.
<h3>Types of scatter Plots</h3><h3></h3>A scatter graph can show:
- Positively correlation
- Negatively correlation or
- Zero correlation

So... let's say the amounts invested were "a" at 6% and "b" at 7.5%.
ok.. hmm what's 6% of a? well, (6/100) * a or 0.06a.
what's 7.5% of b? well, (7.5/100) * b or 0.075b.
now... we know, whatever "a" and "b" are, they total the investment of 5000 bucks, thus a + b = 5000
and the interest yielded was 337.50, thus 0.06a + 0.075b = 337.50
thus
solve for "a", to see how much was invested at 6%.
what about "b"? well, b = 5000 - a.
