Problem
A knitting pattern for a shawl calls for 8
stitches in the first row. Each row after that
has 2 more stitches than the previous row.
The explicit rule ax = 8 + (k − 1)2 gives the
number of stitches in the nth row row.

Which term best describes the association between variables a and b? no association a negative linear association a positive linear association a nonlinear association a scatterplot with an x axis labeled, variable a from zero to ten in increments of two and the y axis labeled, variable b from zero to one hundred forty in increments of twenty with fifteen points in a positive trend.

Suppose i flip two identical coins. what is the probability that i get one head and one tail?

Can someone factor this fully? my friend and i have two different answers and i would like to know if either of them is right. you in advance. a^2 - b^2 + 25 + 10a
