Cientists tag a group of dolphins as they are born and release them in the water. Later, the catch a sample of dolphins that return to shore and check them for tags. In one sample, 40 out of 800 returning dolphins have tags. What is the best prediction of the total number of tagged dolphins in a sample of 2000? There would be about
dolphins that were tagged in the sample of 2000.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce
