Answer:
Step-by-step explanation:
Given that:
Batting average = 0.25 after 160 times at bat;
Batting Average = Number of hits / number of times at bat
0.25 = number of hits / 160
Number of hits = 0.25 * 160 = 40
He want batting average to improve to 0.333 ; if he makes hit the next x times at bat ; number of hits is needed to improve batting average
Hence,
New average = number of hits / number of times at bat
0.333 = (number of hits + x) / (160 + x)
0.333 = (40 + x) / (160 + x)
Answer:
(x,y)=(3/2,7/5)
Step-by-step explanation:
I assume that there is no y component to this question. Since the y value is nonexistent, the rate of change is zero.
A:0
A whole number. The number is 9, because 45/5 = 9.
