When entering the formula, F4 key lets you can toggle between relative and absolute referencing. Then in Column T, calculate the square of the value in column S. In T32, use the function SUM to total the values in

This pedigree shows the pattern of children with albinism in a family. If two carriers have children, the probability of the couple having a child with albinism equals 1/4 and the probability of having a child without albinism equals 3/4. In this case, what is the probability that a couple will have a first child with albinism and then have a

You are the manager of a musician, and it is estimated that if x dollars is spent on album promotion and y dollars on artist development, approximately (, ) = . . copies of the album will be sold. You are constrained by the record company budget, that allows you to spend a total of $120,000 on album promotion and artist development. (Algebra

On Off Low Medium 0.47 0.25 0.12 0.07 0.04 0.05 The outcomes of two variables are (Low, Medium, High) and (On, Off), respectively. An experiment is conducted in which the outcomes of each of the two variables are observed. The probabilities associated with each of the six possible outcome pairs are given in the accompanying twoway table. Consider

Your professor's daughter was born with a slightly misshapen head, so she gets to wear a helmet for a few months to correct it. You do a study of how many weeks babies have to wear a helmet to correct a flat head. You find that, in a sample of 200 babies, 49 of them need to wear the helmet for 1-5 weeks, 68 wear the helmet for 6-10 weeks, 53 wear
