If the biologist catches and tags 32 bass and from sample of 55 he found only 5 tagged then there are 352 bas in the lake.
Given Biologist catches and tags 32 bass, when sample of 55 bass is taken then 5 are found tagged.
Population is basically number of living thing exists in a particular area.
Number of bass which are tagged in lake=32
Sample size=55
Number of bass found tagged=5
means percentage of tagged bas found is 5/32*100=1.6%
We have to calculate number of times 5 is multiplied to get 32 which is 6.4.
Number of bass in the lake=55*6.4
=352 basses.
Hence there are 352 basses in the lake if 5 are found tagged in a sample of 55.

Answer:
The sale price of the item is 96 pounds.
Step-by-step explanation:
If all the items are reduced by 20%, this means now their price is 100% - 20% = 80% of the original price.
Therefore, if an item was originally priced at 120pounds, its price now will of 80% of 120 pounds, i.e.
The sale price of the item is 96 pounds.
Answer:
<h2>The third option is correct.</h2>
Step-by-step explanation:
The line D'E' is parallel to the y-axis.
Hence, it is clear that the image is reflected across the y-axis.
If you see closely the given image, you can see that the y ordinates of each point of the Pentagon has shifted 8 points towards the positive direction of y-axis.
Hence, the transformation for the y-coordinates will be Y = y + 8.
Now if you check the transformation for the x-coordinates, you will observe that the coordinates of D and E will be lie on x = -1. After reflection, they will lie on x = 1.
If he only ordered 10 pies at $8.50 each, the total would be $85 +$5 delivery. That would make each pie cost $9.00 each. If he bought 12 pies the total cost would be $102. I think the better deal would be to buy 12 at $8.50 each because the cost different for 2 more pies would only be $12. The last 2 pies would only be $6 each above the cost of the 10 with delivery. My only ? is if they want you to set it up as a proportion, or decide which is the most cost efficient.
