Chapter 1, Problem 14RQ

Calculate the two possible values of x in this equation: x2 – 11x + 24 = 0, either by using the quadratic equation developed by Abu Abd-Allah ibn Musa al-Kwarizmi, or by factoring the integer values of x. x = 24 or 1 x = 6 or 4 x = 5 or 7 D. x = 8 or 3 x = 2 or 12

If one is testing a goodness of fit to a 9:3:3:1 ratio, how many degrees of freedom would be associated with the Chi-square analysis?

If you flip a coin, there is a 1/2 chance you will receive a heads. If you flip a coin twice, you have to use the product rule to multiply each independent flip to find out what the odds of getting two heads in a row. (1/2 x 1/2=1/4.) By this rule, the odds of flipping a coin 13 times in a row twice and getting the exact same thing both times are 213.    (a) Mathematically, what are the chances that any two frog siblings will receive exactly the same complement of chromosomes due to random independent assortment (not counting random genetic recombination) Remember to add together the odds for both egg and sperm. What is this number for a human zygote? What does this tell you about the odds of being identical to one of your siblings, even without taking into account recombination (and not counting identical twins)?   (b) How do the two frog siblings compare? Do they share about 50% of their DNA or a little more or a little less? Is one sibling more or less related to one grandparent or…
