(a) If a kitten weighs 99 grams at birth, it is at 5.72 percentile of the weight distribution.
(b) For a kitten to be at 90th percentile, the minimum weight is 146.45 g.
<h3>
Weight distribution of the kitten</h3>
In a normal distribution curve;
- 2 standard deviation (2d) below the mean (M), (M - 2d) is at 2%
- 1 standard deviation (d) below the mean (M), (M - d) is at 16 %
- 1 standard deviation (d) above the mean (M), (M + d) is at 84%
- 2 standard deviation (2d) above the mean (M), (M + 2d) is at 98%
M - 2d = 125 g - 2(15g) = 95 g
M - d = 125 g - 15 g = 110 g
95 g is at 2% and 110 g is at 16%
(16% - 2%) = 14%
(110 - 95) = 15 g
14% / 15g = 0.93%/g
From 95 g to 99 g:
99 g - 95 g = 4 g
4g x 0.93%/g = 3.72%
99 g will be at:
(2% + 3.72%) = 5.72%
Thus, if a kitten weighs 99 grams at birth, it is at 5.72 percentile of the weight distribution.
<h3>Weight of the kitten in the 90th percentile</h3>
M + d = 125 + 15 = 140 g (at 84%)
M + 2d = 125 + 2(15) = 155 g ( at 98%)
155 g - 140 g = 15 g
14% / 15g = 0.93%/g
84% + x(0.93%/g) = 90%
84 + 0.93x = 90
0.93x = 6
x = 6.45 g
weight of a kitten in 90th percentile = 140 g + 6.45 g = 146.45 g
Thus, for a kitten to be at 90th percentile, the approximate weight is 146.45 g

Answer:
The weight is 18.75 KN/m³ that means
weight = 18750 N/m³
and mass = 1911 kg
Answer:
K ∅ = 1.48 Wb
Explanation:
given data
EA=(82 V/A)
speed = 1,710 rpm
RA = 9Ω
Rad j = 6Ω
RF = 30Ω
voltage VT = 97 V
to find out
Kϕ for the motor in Wb
solution
first we get here shunt field current
shunt field current = ............1
shunt field current =
shunt field current IF = 3.233 A
and
now we get here induced emf for field current that is
induced emf = 82 IF
induced emf = 82 × 3.233
induced emf = 265.133 V
and induced emf EA is also express as
induced emf EA = K∅ω .....................2
EA = K ∅ ×
put here value
265.133 = K ∅ ×
solve we get
K ∅ = 1.48 Wb
Metallic glasses are sometimes formed when molten metal is cooled too fast for its atoms to arrange themselves in a structured, crystalline order. "The material can't decide which crystalline structure it wants to converge to, and a metallic glass emerges
A model of living systems as whole entities which maintain themselves through continuous input and output from the environment, developed by ludwig von bertalanffy is known as Systems theory.
<h3>
what are the application of systems theory?</h3>
It is a theoretical framework to understand the working mechanism of an organization.
It is an entity where all the elements necessary to carry out its functions.
A computer is the best example of showing the mechanism of system theory.
computer is a system which has many smaller sub-systems that have to work in coordinated manner.
These sub-systems are the processor, RAM, motherboard, hard drive and power supply.
