Peter attempted to use the divide-center method to find the line of best fit on a scatterplot what was his mistake?
a. he had a different number of points to the left of the vertical line than to the right of the vertical line.
b. he had a different number of points above the line of best fit than below the line of best fit.
c. he didn’t approximate the center of the cluster located on the left side of the vertical line and of the cluster located on the right side of the vertical line.
d. he didn’t connect the centers of the clusters on the left side and right side of the vertical line to produce the line of best fit. mark this and return

A.

Explanation:

He had a different number of points to the left of the vertical line than to the right of the vertical line.

The divide-center method requires dividing the data into two equal groups, approximating the center of each group and constructing a line between the two centers.

So the fact that he had different number of points, messed up his efforts to find the line of best fit on the scatterplot.

a. He had a different number of points to the left of the vertical line than to the right of the vertical line.

Explanation:

sorry but your romanian isn't clear could you just translate to english

explanation:

jupiter is mainly composed of hydrogen and helium just like a star. spectral analysis of jupiter has revealed that in addition to hydrogen and helium, the planet is made of water, methane and ammonia. those elements are in trace amounts. the core of the planet is thought to contain some rock and metallic hydrogen. i hope this will give you the answer to your question! : d
