Pretty sure the answer is 8
Answer:
D)
Step-by-step explanation:
ASSUMING NORMAL DISTRIBUTION, LESS THAN 10% AT LOWER END
OF 15.34 MEANS [DENOTING MEAN BY M AND Standard Deviation. BY S]
M±AS=20%....................M-AS=15.34
FOR 20% LEVEL .......A=1.281........FROM TABLES
M-1.281×S=15.34............................1
SIMILARLY
M±BS=40%...................M+BS=16.31
FOR 40% LEVEL .............B=0.841...................FROM TABLES
M+0.841×S=16.31.............................2
EQN.2 - EQN.1
2.122×S=0.97
S=0.457=0.46
M=15.926= 15.93
HENCE, D IS THE ANSWER
that is D. μ = 15.93, σ =.46

Given equation:
<u>Standard equation of a circle:</u>
(where 
is the centre of the circle, and 
is the radius)
If you expand this equation, you will see that the coefficient of 
is always one.
Therefore, 
<u>Additional information</u>
To rewrite the given equation in the standard form:
So this is a circle with centre (2, -3) and radius √29
