Answer:
1. a. 25(1) + 10(2) + 3(3) + 10(4) = 94/140 = .671
2. b. Mark’s average < Jay’s average
Step-by-step explanation:
1. What is Mark’s slugging average?
The slugging average gives more weight to the multi-base hits (compared to single-base hits) in opposition with the batting average.
So, a single hit is worth 1 point, a double is worth 2 points, a triple 3 points and a homerun is worth 4 points. It's a weighted average calculation.
Mark had 25 singles, 10 doubles, 3 triples and 10 homeruns during 140 presences 140 at bat.
25(1) + 10(2) + 3(3) + 10(4) = 94/140 = .671
2. How does Mark's average compares to Jay's?
Let's first calculate Jay's slugging average then we'll be able to decide.
Jay had 10 singles, 6 doubles, 5 triples and 14 homeruns in 90 presences.
10 (1) + 6 (2) + 5 (3) + 14 (4) = 10+12+15+56 = 93 / 90 = 1.033
We can definitely say that Mark's slugging average (0.671) calculated above is lower than Jay's average (1.033). So,
b. Mark’s average < Jay’s average
