Answer:
I believe it would be the 3rd answer.
Step-by-step explanation:
That answer is the only one where not only do one of the systems have that point but they both do. That is where they intercept. Plus when you fit in the x and y points in the equations they match up. Hope that helps!
120
for
to be equal to ![\frac{15}{?}](https://tex.z-dn.net/?f=%5Cfrac%7B15%7D%7B%3F%7D)
consider the numerators 8 × 8 = 64, the numerator of the second fraction
We must therefore multiply the denominator by 8
15 × 8 = 120
thus
= ![\frac{64}{120}](https://tex.z-dn.net/?f=%5Cfrac%7B64%7D%7B120%7D)
I wanna say the answer is A
PART A:
The data is plotted in the graph below. The line best fit is drawn to show the trend of the data. Since the plots form a cluster that follows the line best fit and there are no outliers, the most likely coefficient is 0.94 which is a strong positive correlation.
PART B:
The value of slope between x = 5 and x = 10 is
Slope = (3-1) ÷ (10-5) = 2/5
The slope represents the rate of change of the radius, which is 2/5 for every 5 days
PART C:
The data in the table represents correlation, that the algae grow longer as the days increase. It might not be necessary a causation because the growth of algae doesn't necessarily depend on the number of days.
