Answer:
187.5 m^3
Step-by-step explanation:
2 to 5 is 2(2.5)
2.5^2 = 6.25
6.25(30) = 187.5
Answer:
Step-by-step explanation:
Given:
Type of Flowers = 5
To choose = 4
Required
Number of ways 4 can be chosen
The first flower can be chosen in 5 ways
The second flower can be chosen in 4 ways
The third flower can be chosen in 3 ways
The fourth flower can be chosen in 2 ways
Total Number of Selection = 5 * 4 * 3 * 2
Total Number of Selection = 120 ways;
Alternatively, this can be solved using concept of Permutation;
Given that 4 flowers to be chosen from 5,
then n = 5 and r = 4
Such that
![nPr = \frac{n!}{(n - r)!}](https://tex.z-dn.net/?f=nPr%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n%20-%20r%29%21%7D)
Substitute 5 for n and 4 for r
![5P4 = \frac{5!}{(5 - 4)!}](https://tex.z-dn.net/?f=5P4%20%3D%20%5Cfrac%7B5%21%7D%7B%285%20-%204%29%21%7D)
![5P4 = \frac{5!}{1!}](https://tex.z-dn.net/?f=5P4%20%3D%20%5Cfrac%7B5%21%7D%7B1%21%7D)
![5P4 = \frac{5*4*3*2*1}{1}](https://tex.z-dn.net/?f=5P4%20%3D%20%5Cfrac%7B5%2A4%2A3%2A2%2A1%7D%7B1%7D)
![5P4 = \frac{120}{1}](https://tex.z-dn.net/?f=5P4%20%3D%20%5Cfrac%7B120%7D%7B1%7D)
![5P4 = 120](https://tex.z-dn.net/?f=5P4%20%3D%20120)
Hence, the number of ways the florist can chose 4 flowers from 5 is 120 ways
Answer:
Step-by-step explanation:
Sum
-2d + 1 + 6d + 4
Solving like terms
4d + 5
Difference
-2d + 1 - 6d - 4
-8d - 3
Answer:
Step-by-step explanation: First, you need to write all your data down from least to greatest. Next, count up all the numbers to see how many students. Then you want to find the mean which is average (add then divide). Median is the middle so you will x each number out till you get to the middle, and if the middle is 2 numbers, you find the average of them to find the median. Mode means most often. Range is highest minus lowest. And you can do the next 2.
For this problem, all you need to do is find the three #'s that add up to 156.
So, lets look at the answers and add them up.
A. 50, 52, 54
50 + 52 + 54 = 156
B. 51,52,53
51 + 52 + 53 = 156
C. 49,50,51
49 + 50 + 51 = 150
D. 49,51,53
49 + 51 + 53 = 153
We get the answers (50,52,54) and (51,52,53)
Now, consecutive numbers are numbers that in order, like 1,2,3.
Therefore, the answer is (51,52,53)
