Answer:
Let there were total x people at the conference
so 32%of x is 216
32/100×x=216
x=216×100/32
x=675
So total people present at the conference were 675
The equation has no X variable so whatever that adds up to becomes the y-intercept.
- 2/9 + 1/5 >> - 10/45 + 9/45 = - 1/45
Your y-int is - 1/45 or (0, - 1/45)
Answer:
GUESS AND THERES NOTHING TO SOLVE
Step-by-step explanation:
Given:
Sum of two consecutive integers is 325.
To find:
The number that is the least of the two consecutive integers.
Solution:
Let the two consecutive integers are x and x+1. So,
![x+(x+1)=325](https://tex.z-dn.net/?f=x%2B%28x%2B1%29%3D325)
![2x+1=325](https://tex.z-dn.net/?f=2x%2B1%3D325)
Subtract 1 from both sides.
![2x=324](https://tex.z-dn.net/?f=2x%3D324)
Divide both sides by 2.
![x=\dfrac{324}{2}](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B324%7D%7B2%7D)
![x=162](https://tex.z-dn.net/?f=x%3D162)
The second integer is
![x+1=162+1=163](https://tex.z-dn.net/?f=x%2B1%3D162%2B1%3D163)
Since
, therefore, the least of the two consecutive integers is 162.
The mean = 28.55, while the standard deviation is 13.16

<h3>How to calculate for the mean of the data set</h3>
We have the following numbers
24 30 4 42 40 26 23 36 12 45 29 21 34 16 47 28 32 54 19 9
The sum of these numbers is given as
571
The total numbers = 20
The mean = 571/20
= 28.55
<h3>2 = How to find the standard deviation</h3>
= (24 - 28.55)2 + ... + (9 - 28.55)/20 - 1
= 3292.95/19
= 173.31315789474
s = √173.31315789474
= 13.164845532506
