Answer:
The correct answer is 0.125.
Step-by-step explanation:
Anne has 8 unmarked computer disks in a box, namely one of English, Spanish, Mathematics, computer science, biology, SAT preparation, college applications, and American history.
Let the experiment be to pick up the SAT preparation disk from this set of 8 disk
Possible outcome is only one as there is only one SAT preparation disk.
Total number of outcomes, i.e. total number of disks available is 8.
Probability of picking of SAT preparation disk is
Probability = 
= 
.
Answer:
17w + 8
Step-by-step explanation:
You would add 6w + 11w because they are like expressions. They you would add 4+4 because they are also like expressions.
X Times x is x^2
X^2-8x+3x-24
x^2-5x-24
Seeing your method 1 answer, it seems like you forgot that 42 dollars is for 6 guests, not just 1. The unit rate is the rate per guest, and if we divide 42 by 6, we get 7dollars/1person as our unit rate. Since 7 dollars is our unit rate, we can multiply that by 72 to get 504 dollars, therefore making 500$ per night more cost effective.
Another way to do this is to do 42*72, as you did, but then dividing the final product by 6 due to that 42*72 is for 72*6=432 guests (we get the 6 since the unit rate is 7$ per person and 42/7=6). Doing that, we get 3024/6=504, which is still greater than 500
<u>Answer:</u>
There are 243 ducks in the preserve.
<u>Explanation:</u>
Given:
In a wildlife preserve, 45 ducks are captured, tagged, and released.
Later, 200 ducks are examined, and two of them are tagged.
To Find:
To estimate how many ducks are in the preserve =?
Solution:
Now, we know that, out of 200 2 ducks are tagged, which means remaining 198 ducks are untagged.
Now, total ducks count = ducks with tags + ducks with out tag
Total ducks count = 45 + 198
Total ducks count = 243
Hence, there are 243 ducks in total.
