Colleges often rely heavily on raising money for an "annual fund" to support operations. Alumni are typically solicited for donations to the annual fund. Studies suggest that the graduate's annual income is a good predictor of the amount of money he or she would be willing to donate, and there is a reasonably strong, positive, linear relationship between these variables. In the studies described: a.annual income is an explanatory variable. b.the correlation between annual income and the size of the donation is positive. c.the size of the donation to the annual fund is the response variable. d.All of the answer options are correct. I choose a card at random from a well-shuffled deck of 52 cards. The probability that the card chosen is a spade or a black card is: a.37/52 b.38/52 c.39/52 d.36/52

In the studies described:

	a.	annual income is an explanatory variable.
	b.	the correlation between annual income and the size of the donation is positive.
	c.	the size of the donation to the annual fund is the response variable.
	d.	All of the answer options are correct.

I choose a card at random from a well-shuffled deck of 52 cards. The probability that the card chosen is a spade or a black card is:
