5.5%= 0.055
0.055*495= 27.225
The commission is $27.225 or ~$27.23
Answer:
Step-by-step explanation:
- 2x + 3y = -1 is the equation of a line
Pick any values for x then find y or for y and then find x;
if you have two points you can draw a line trough those two points.
For example,
pick x= -1 then find y
- 2*(-1) + 3y = -1
2+ 3y = -1
3y = -1-2
y= -3/3
y= -1
First point has the coordinates (-1, -1)
pick y = 1 then find x
- 2x + 3*1 = -1
-2x +3 = -1
-2x = -1-3
-2x = -4
x= -4/-2
x= 2
Second point has the coordinate (2, 1)
Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1
The Mean = (135 + 71 + 69 + 80 + 158 + 152 + 161 + 96 + 122 + 118 + 87 + 85 ) : 12 = 111.166
The smallest value : 69
The greatest value : 161
s² = ∑( x i - x )² / ( n - 1 )
s² = ( 568.274 + 1613.3 + 1777.97 + 971.32 + 2193.42 + 1667.4 + +2483.42 + 230 + 117.38 + 46.7 + 584 + 684.66 ) : 11
s² = 1176.1676
s = √s² = √1176.1676
s ( Standard deviation ) = 34.295
All the values fall within 2 standard deviations:
x (Mean) - 2 s and x + 2 s
Answer:
second one
Step-by-step explanation:
Notice that there's a y intercept of 2 and an x intercept of -4
This means that the line has a positive slope of 1/2, which leaves us with
y<(1/2)x+2
Answer:
![Probability = \frac{1}{8}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%7D%7B8%7D)
Step-by-step explanation:
Given
Represent Boys with B and Girls with G
![P(B) = \frac{1}{2}](https://tex.z-dn.net/?f=P%28B%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
![P(G) = \frac{1}{2}](https://tex.z-dn.net/?f=P%28G%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D)
Required
Find the probability or having 1 boy 2 girls
Since the order is not important, the probability is calculated as follows;
![Probability = P(B) * P(G) * P(G)](https://tex.z-dn.net/?f=Probability%20%3D%20P%28B%29%20%2A%20P%28G%29%20%2A%20P%28G%29)
Substitute
for P(B) and P(G)
![Probability = \frac{1}{2} * \frac{1}{2} * \frac{1}{2}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20%5Cfrac%7B1%7D%7B2%7D%20%2A%20%5Cfrac%7B1%7D%7B2%7D)
![Probability = \frac{1 * 1 * 1}{2 * 2 *2}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%20%2A%201%20%2A%201%7D%7B2%20%2A%202%20%2A2%7D)
![Probability = \frac{1}{8}](https://tex.z-dn.net/?f=Probability%20%3D%20%5Cfrac%7B1%7D%7B8%7D)
<em>Hence, the fractional probability is </em>
