Answer:
The angle of DC is 130°.
Step-by-step explanation:
Given tha total angle in a centre(O) of circle, is 360. So in order to find ∠DOC, you have to subtract 85° and 145° from 360° :
∠COD = 360° - ∠COE - ∠DOE
= 360° - 85° - 145°
= 130°
Answer:r = -1
Step-by-step explanation:
8+8r-(3+3r)=0
We add all the numbers together, and all the variables
8r-(3r+3)+8=0
We get rid of parentheses
8r-3r-3+8=0
We add all the numbers together, and all the variables
5r+5=0
We move all terms containing r to the left, all other terms to the right
5r=-5
r=-5/5
r=-1
Hope this helps
Answer:
Option B) census
Step-by-step explanation:
We have to find the measure of center.
The measure of center is also known as the measure of central tendency.
The measure of central tendency for a data is given by
- Mean
- Median
- Mode
It help us to identify the central position of data in different ways.
Thus, out of the given option census is not a measure of center.
Option B) census
Exponent rule : a^-b = 1 / a^b
52^-5 =
1 / 52^5 =
1 / (52 * 52 * 52 * 52 * 52)
