10>X>0 this is x being greater than 0 and less than 10
The coordinates of the center of this circle will be the average between the extreme points
C = ( (xo+x1)/2 , (yo+y1)/2)
Where,
xo = 3 and x1 = 9
yo = 8 and y1 = 16
Then us stay with"
C = ( (3+9)/2 , (8+16)/2)
C = ( 12/2 , 24/2)
C = ( 6 , 12 )
Let x represent number of bicycles and y represent number of tricycles.
We know that a bicycle has 2 pedals and a tricycle has 32 pedals as well.
We have been given that when the owner counted the total number of pedals of the cycles, he got 50. We can represent this information in an equation as:
![2x+2y=50...(1)](https://tex.z-dn.net/?f=2x%2B2y%3D50...%281%29)
![2x=50-2y...(1)](https://tex.z-dn.net/?f=2x%3D50-2y...%281%29)
We know that a bicycle has 2 wheels and a tricycle has 3 wheels.
We have been given that when the owner counted the total number of wheels of the cycles, he got 64. We can represent this information in an equation as:
![2x+3y=64...(2)](https://tex.z-dn.net/?f=2x%2B3y%3D64...%282%29)
Upon substituting equation (1) in equation (2), we will get:
![50-2y+3y=64](https://tex.z-dn.net/?f=50-2y%2B3y%3D64)
![50+y=64](https://tex.z-dn.net/?f=50%2By%3D64)
![50-50+y=64-50](https://tex.z-dn.net/?f=50-50%2By%3D64-50)
![y=14](https://tex.z-dn.net/?f=y%3D14)
Therefore, 14 tricycles were offered in the sale.
Answer:
Step-by-step explanation:
Both angles are supplementary (they add up to 180°)
This means that (10x) + (6x - 12°) = 180°
(10x) + (6x - 12°) = 180°
10x + 6x - 12° = 180°
16x - 12° = 180°
16x = 192°
x = 12°
Hope this helps!
Answer:
The standard deviation on the critical path = 0.834
Step-by-step explanation:
Variance of activity A (
) = 0.33
Variance of activity B (
) = 0.67
Variance of activity C (
) = 0.33
Variance of activity D (
) = 0.17
Thus the standard deviation on the critical path (
) =
+
+
+ ![V^2_{4}](https://tex.z-dn.net/?f=V%5E2_%7B4%7D)
=
+
+
+
= 0.6956
= 0.834
The standard deviation on the critical path = 0.834
