0.65 = 65/100 which simplifies to 13/20 ( by dividing 65 and 100 by 5)
Spoas a mixed number 5.65 is 5 13/20
Answer:
Step-by-step explanation:
Given
Line A:
Line B:
Required
Determine the equation of Line B
First, we need to determine the slope of A using
Where:
By comparison:
Since A and B are perpendicular:
The slope of B (m2) is:
The equation of B is calculated as thus:
Where
So, the equation becomes
Open bracket
Make y the subject
B is the answer because when it comes to negative digits (-x) it is always the opposite of positive digits
if 3 is greater than 2 than -3 will be smaller than -2.
Actually this is because when we see the number line we come to know the order of all integers and that's when we see -2 after -3 (Left to right)
Answer: The radius of the circle is 7.75 m (approximately)
Step-by-step explanation: The area of a sector is determined as follows;
Area of sector = (∅/360) x πr²
The area has been given as 10π, and the angle subtended by the sector has been given as 60. Substituting for known values we now have;
10π = (60/360) x πr²
10π = (1/6) x πr²
By cross multiplication we now have;
(10π/π) x 6 = r²
10 x 6 = r²
60 = r²
Add the square root sign to both sides of the equation
√60 = √r²
7.7459 = r
The radius of the circle is approximately 7.75 meters
Answer:
R indicates Random Assignment
Step-by-step explanation:
In designing an experiment, R is the symbol used for assigning the subjects randomly to different groups through randomization. It is called random assignment and It is the option (d) random assignment. It is achieved by using chance procedure ( random number generator, by flipping coin, throwing ). This ensures that all the subjects have equal chance of placing in all the groups.
Option (a) Symbol O is used for Observations. (So option (a) is wrong answer)
Option (b) Symbols x , y are used as Observational variables (So option (b) is wrong answer)
Option (c) Comparison groups is wrong answer as R is not used for that.
