19/25 * 100 = 1900/25 = 76 ....numbers greater then 15
7/50 * 100 = 700/50 = 14....numbers less then 15
100 - (76 + 14) = 100 - 90 = 10 <== numbers equal to 15
X/3=x+2/5
5x = 3(x+2)
5x = 3x + 6
2x = 6
x = 3
answer
D.3
Answer: It is sufficient evidence that it will reject the null hypothesis.
Step-by-step explanation:
Since we have given that
Number of players of baseball games = 162
Number of games won = 97
So, 
Hypothesis:

So, test statistic would be

And the p-value = 0.006 at z=2.514.
Since p-value < α = 0.10 significance level.
Hence, it is sufficient evidence that it will reject the null hypothesis.
A 48 pi in 2 It’s pretty easy just find the formula for it and plug the numbers in on a calculator.
