Answer:
3/8
Step-by-step explanation:
Given that
Number of clown fish = 10
Number of Angel fish = 4
Number of Puffer fish = 6
Number of Eels = 5
From the above, there exists 10 + 4 + 6 + 5 number of fishes
There exists 25 number of fishes.
Probability of picking a clown fish then is
C = 10 / 25
If the clown fish picked isn't replaced, then there exists 9 clown fishes, and 24 total fishes. This, the probability of picking another clown fish is
C = 9 / 24
C = 3 / 8
Thus, the answer is 3/8
Answer: the building is about 63 feet
Step-by-step explanation:
You can use 1 of 2 methods to solve this problem. You can either solve it traditionally or by just looking at it (you don't necessarily need to convert it to scientific notation to find the answer).
{METHOD 1}- Traditional Method
Scientific Notation is just another way of writing REALLY BIG or REALLY SMALL numbers in a simplified manor
Let's take 232,000,000 for instance
First you want to find your decimal number. Your decimal number has to be Greater than 1 and less than 10.
In this case your decimal number will be 2.32
Then let's could how many decimal places are to the RIGHT of 2.32
Keep in mind that if the number is very small you have to count the decimal places to the LEFT
{METHOD 2}
If you look at 232,000,000 and 2,320,000,000 you can tell that 2,320,000,000 is longer just by looking at it, so you can determine that ....
232,000,000 = 2.32E8
2,320,000,000=2.32E9
Using the same method you can solve the last two.
0.00000431 is a larger number than 0.000000000000431. So you can then determine that.....
0.00000431= 4.31E-6
0.000000000000431=4.31E-13
The answer is equation 2 as it expands to 0=0
B. is true. 15·(–5) > 23·(–12).
15·(-5)=-75.
23·(-12)=-276.
-75 > -276
