Question
Refer to Exercise $45 .$ A trout caught by Ashley is $20 \%$ longer and has a girth that is $10 \%$ shorter than the one caught by Jane.a. Whose catch is heavier?b. By how much does the weight of Ashley's catch differ from the weight of Jane's catch?
Step 1
The weight \( W \) of a fish can be estimated using the formula: \[ W = \frac{L \times G^2}{800} \] where \( L \) is the length of the fish in inches, and \( G \) is the girth of the fish in inches. Show more…

Two fish are caught and weighed. Consider the events A = {the first weighs more than 10 pounds}, B = {the second weighs more than 10 pounds}, and C = {the sum of the weights is more than 20 pounds}. Argue that C ⊆ A ∪ B.
Solve each problem. The weight of a trout varies jointly as its length and the square of its girth. One angler caught a trout that weighed 10.5 lb and measured 26 in. long with an 18 -in. girth. Find the weight of a trout that is 22 in. long with a 15 -in. girth.

Solve each problem. The weight of a trout varies jointly as its length and the square of its girth. One angler caught a trout that weighed $10.5 \mathrm{lb}$ and measured 26 in. long with an 18 -in. girth. Find the weight (to the nearest tenth of a pound) of a trout that is 22 in. long with a 15 -in. girth.
