Answer: Number of ways 
Step-by-step explanation:
When there is no replacement , we use combination to find the number of ways to choose things.
Number of ways to choose r things out of ( with out replacement) = 
The number of ways to choose 8 things = ![^8C_8=\dfrac{8!}{8!(8-8)!}=\dfrac{1}{0!}=1 [\because 0!=1]](https://tex.z-dn.net/?f=%5E8C_8%3D%5Cdfrac%7B8%21%7D%7B8%21%288-8%29%21%7D%3D%5Cdfrac%7B1%7D%7B0%21%7D%3D1%20%20%5B%5Cbecause%200%21%3D1%5D)
Hence, Number of ways
Answer:

3a -2
Answer:
2
Step-by-step explanation:
there would be 2 in every group, 10 divided by 5
Well, 4 + 6 + 9 = 19, so $14 is a reasonable answer. If we have $19 assuming that each flower costs $1, then if the estimate is $14, that means that each flower is less than $1, which makes sense. Assuming that all of the flowers cost the same, then each flower would be about 74 cents. This would make sense considering that you are buying tulips, roses, and carnations. I really hope this helps; if not, good luck on your homework.
