make a design or sketch plan of a rectangular wooden chair that can be made out of a 1/2" x 10" x 5' wood and 2" x 3" x 8' wood. Using the design or sketch plan, formulate one problem that involves Quadratic Equations, then solve in two different ways.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

i dont understand the question? ?

step-by-step explanation:

answer: the center is the median and/or mean of the data. the spread is the range of the data. and, the shape describes the type of graph. the four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. good luck
