Answer: 90°
Step-by-step explanation:
A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. ... The mean (often called the average) is most likely the measure of central tendency that you are most familiar with, but there are others, such as the median and the mode.
Answer:
M = 8 N = 10
Step-by-step explanation:
Multiplying exponents adds the exponent, meaning that inside of the brackets, it is a^4 * b^5. Multiply the exponents by two because you are squaring the entire equation. Therefore, m=8 and n=10
Answer:
-1-3 = -4
Step-by-step explanation:
Answer:
68
Step-by-step explanation:
1) Plug In (when you plug in you replace the defined variable with the number given. usually you have to find the numbers to plug in but since they're already given to you you just plug them in.) 4(3) + 8(7)=T T= total cost
2) Multiply 4*3=12 8*7=56
3) Add 12+56=68
4) <u>T=68</u>
Answer:
840
Step-by-step explanation:
Given
![DJs = 7](https://tex.z-dn.net/?f=DJs%20%3D%207)
![To\ pick = 4](https://tex.z-dn.net/?f=To%5C%20pick%20%3D%204)
Required
Determine the number of rankings
The term "ranking" as used in this question implies permutation and the required is calculated using:
![^nP_r = \frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5EnP_r%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
Where
![n = 7](https://tex.z-dn.net/?f=n%20%3D%207)
![r = 4](https://tex.z-dn.net/?f=r%20%3D%204)
So:
![^nP_r = \frac{n!}{(n-r)!}](https://tex.z-dn.net/?f=%5EnP_r%20%3D%20%5Cfrac%7Bn%21%7D%7B%28n-r%29%21%7D)
![^7P_4 = \frac{7!}{(7-4)!}](https://tex.z-dn.net/?f=%5E7P_4%20%3D%20%5Cfrac%7B7%21%7D%7B%287-4%29%21%7D)
![^7P_4 = \frac{7!}{3!}](https://tex.z-dn.net/?f=%5E7P_4%20%3D%20%5Cfrac%7B7%21%7D%7B3%21%7D)
![^7P_4 = \frac{7 * 6 * 5 * 4 * 3!}{3!}](https://tex.z-dn.net/?f=%5E7P_4%20%3D%20%5Cfrac%7B7%20%2A%206%20%2A%205%20%2A%204%20%2A%203%21%7D%7B3%21%7D)
![^7P_4 = 7 * 6 * 5 * 4](https://tex.z-dn.net/?f=%5E7P_4%20%3D%207%20%2A%206%20%2A%205%20%2A%204)
![^7P_4 = 840](https://tex.z-dn.net/?f=%5E7P_4%20%3D%20840)
<em>Hence, number of ranking is 840</em>
