Consider the following distribution of scores with a mean of 80 and a standard deviation of 20. For the letters A, B, C, and D in the boxes beneath the line labeled “z” give the z-scores corresponding to each position in the distribution. One z-score is already filled in (–1). Suppose you also want to standardize these scores to a “k” scale where the mean of k is 50 and the standard deviation is 10. For the letters E, F, G, and H in the boxes beneath the line labeled “k” give the k-scores corresponding to each position in the distribution. One k-score is already filled in (60).

You buy five cds at a sale for $5.95 each. write an expression for the total cost of the cds.then use the distributive property and mental math to evaluate the expression.
