A normal distribution is, where we have normal and equal skew between left and right portions of the distribution. We can see that the graph is equal at center.
A positively skewed graph, the graph inclines on the positive side of the graph and in negative skewed graphs, they are inclined towards the negative side.
Five less than twice what negative number squared is 157 <- put into an expression -5 + 2(-x^2) = 157 Now simplify: -5 + -2x^2 = 157 -2x^2 = 162 -2x^2 - 162 = 0 2x^2 + 162 = 0 x^2 + 81 = 0
