The total amount of cookies that were made was 48.
If they give half of the cookies (48 cookies total) to the class, the give half of what is left (24 is left), and they eat 12, the the answer is 48 cookies total.
There is no solution.
If you divide both sides by -3 to get the variable isolated, it is
|s| = -6
Absolute value equations cannot equal negative numbers, so there is no solution.
Just divide 21/1/3 and that number multiplied by 4
They are not equivalent fractions.
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.
