Step-by-step explanation:
2300 out of 4500 were chosen
2300 / 4500 = 0.5111
0.51 = 51%
51% is the acceptance rate.
Given:
The shaded sector above covers
of the circle.
Radius of the circle = 3 cm
To find:
The area of the sector in terms of π.
Solution:
The area of a circle is

Substituting
, we get


It is given that the shaded sector above covers
of the circle.
The area of shaded sector 


Therefore, the area of shaded sector is 3π sq. cm.
Answer:
C. 1
Step-by-step explanation:
We can see that each box in the grid is one unit.
We count one box to the right on the horizontal axis and 4 boxes down on the vertical axes to obtain the components of vector v.
See graph in attachment.
Therefore the components of vector v is

.
The length of the x component is 1 unit
Hence the correct answer is C.
X = 4/15. The topic is solving for unknowns in an equation.
