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:
165 square cm
Step-by-step explanation:
Area of a circle is , where r = radius. We're given the radius as 7.25.

- 165.04625 ≈ 165 square cm
Therefore, the answer is 165 square cm.
The probability of picking a blue jelly bean is 10/12=0.833, since there are 10 blue and 12 jelly beans in total.
Each time the probability of picking blue is the same, since put back in the box whatever jelly bean we pick
P(blue, blue, blue) = P(blue) × P(blue) × P(blue) = 0.833×0.833×0.833=0.579
Answer: 0.579
36 x 3/9.
3/9 = 0.33
0.33 x 36 = 12
Answer:
24=0.5r+21.5
Step-by-step explanation:
y=mx+b
24= how much money you have
0.5= cost of each ride
r=number of rides you can ride
21.5= price it takes to enter
