7-5=2
You find the differences
<u>Given</u>:
Given that the radius of the figure is 6 units.
We need to determine the area of the shape.
<u>Angle of the shape:</u>
The angle of the shape is given by

Hence, the angle of the shape is 270°
<u>Area of the shape:</u>
The area of the shape can be determined using the formula,

Substituting r = 6, we get;

Simplifying, we get;


Thus, the area of the shape is 84.78 square units.
Answer:
1
Step-by-step explanation:
Answer:
ntersecting lines DA and CE.
To find:
Each pair of adjacent angles and vertical angles.
Solution:
Adjacent angles are in the same straight line.
Pair of adjacent angles:
(1) ∠EBD and ∠DBC
(2) ∠DBC and ∠CBA
(3) ∠CBA and ∠ABE
(4) ∠ABE and ∠EBD
Vertical angles are opposite angles in the same vertex.
Pair of vertical angles:
(1) ∠EBD and ∠CBA
(2) ∠DBC and ∠EBA
Answer:
92.65 % light bulbs last less than 2080 hours
Step-by-step explanation:
We are given that The amount of time a certain brand of light bulb lasts is normally distributed
Mean =
Standard deviation =
We are supposed to find What percentage light bulbs last less than 2080 hours, to the nearest tenth

Z=1.45
Refer the z table for p value
p value = 0.9265
Hence 92.65 % light bulbs last less than 2080 hours
