On a county-wide baseball team, the best players were sent from each high school. there are three mutually exclusive categories of players on this team: infielders, outfielders, and pitchers. if the ratio of infielders to outfielders is 7: 4, and the ratio of pitchers to outfielders is 5: 3, then if we pick one player at random from the county-wide baseball team, what is the probability that we will pick a pitcher?

What is the correlation coefficient for the data? don't forget to turn the diagnoisticon (in the catalog menu of the calculator). r = answer (round to the nearest thousandth)

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.

Evaluate this using ! 0.25^2 x 2.4 + 0.25 x 2.4^2 − 0.25 x 2.4 x 0.65
