PLEASE NEED HELP URGENTLY! Raul tried to find the midpoint between 5 & 3i and 12 + 7i. Check his work below.

Sum=(5+(-3))+(12+7)i

=2+19i

so the midpoint is 1+ 19over2 i

What mistake did Raul make?

AHe subtracted the values instead of adding them.

BHe did not add the corresponding parts of the complex numbers.

CHe found the sum instead of the average because he forgot to divide by two.

DHe added the numbers in the wrong order.

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to
