Question

c. the fish and wildlife agency measured the size of pacific salmon for 1 year and recorded the average weight for each species.
table: salmon species (king, sockeye, silver, chum, humpback); average weight (lbs) (15, 8, 12, 15, 5)

Explanation:

Step1: Identify the weights

The weights for each salmon species are: King = 15 lbs, Sockeye = 8 lbs, Silver = 12 lbs, Chum = 15 lbs, Humpback = 5 lbs.

Step2: Calculate the sum of weights

Sum = \( 15 + 8 + 12 + 15 + 5 \)
\( = 15+8 = 23 \); \( 23+12 = 35 \); \( 35+15 = 50 \); \( 50+5 = 55 \)

Step3: Calculate the average

There are 5 species, so average = \( \frac{55}{5} \)
\( = 11 \)

Answer:

The average weight for each salmon species is 11 lbs.
