Answer:
0.0445937
Step-by-step explanation:
-Given that the sample statistic has a mean of 406 grams, standard deviation of sq root(225) and the null statistic is 411 grams.
-Assuming normal distribution, the test statistic is calculated as:

-we then find the p-value of the test statistic from the z-tables:
P-value=0.0445937
You would solve this by writing it as a porpotion. It would be 25/100=161.25/x. Then, you would multiply the 100 and 161.25, which would get you 16125, then you would divide this by 25, which would get you your answer : $645.
Well, it is bass times height divided by two
Length: 2x-1, width: x
A=LW
120=x(2x-1) 120=2x^2-x 0=2x^2-x-120, Factor (x-8)(2x+15)=0
x=8 is the width and 15 is the length
