Suppose that the weights for newborn kittens are normally distributed with a mean of 125 grams and a standard deviation of 15 grams. Determine the following. You must show your work or explain the reasoning or process you used to arrive at your answers. Please circle or highlight your final answers.
a. If a kitten weighs 99 grams at birth, what percentile of the weight distribution is it in?
b. How heavy must a kitten be, at a minimum, to be in the 90 th percentile (i.e. 90% of kittens weigh less than this amount)?
(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.
Weight distribution of the kittenIn 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.
Weight of the kitten in the 90th percentileM + 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

In a basketball game, the point guard A intends to
throw a pass to the shooting guard B, who is breaking
toward the basket at a constant speed of 12 ft /sec. If
the shooting guard is to catch the ball at a height
of 7 ft at C while in full stride to execute a layup,
determine the speed v0 and launch angle with
which the point guard should throw the ball
In a basketball game, point guard A intends the speed as 47.76 ft/sec, and the launch angle will be 41.084°.
What is the projectile motion?The projectile motion is given as the motion of the object in the curved path near the earth's surface. The throwing of the ball will follow the projectile motion.
The missing image is attached below.
The given game situation consists of:
Velocity of shooting guard (vs) = 12 ft/sec.
Distance from B to C (sc) = 20 ft
Final height to catch the ball, 7 ft
The total distance to cover from B to C = 60 ft
Time is taken to reach B to C = Distance/Speed
Time to reach B to C = 20ft/12ft/sec
Time to reach B to C = 1.667 sec.
The time taken to cover the horizontal distance:
Distance = Velocity * Time
60³ = v₀cosθ * distance/time
60³ = v₀cosθ * 20/12
v₀cosθ = 36 ft/sec
The vertical movement can be given where, g = 32.2 ft/sec²:
s = s₀ + v₀sinθ * time + 1/2 -g time²
7 = s + v₀sinθ * 20/12 - 1/2 32.2 ft/sec² * (20/12)²
v₀sinθ = 31.3875 ft/sec
[tex]\rm v_0 =\sqrt{v_0sin\theta^2\;+\;v_ocos\theta^2}[/tex]
Substituting the values:
v₀ = 47.76 ft/sec
The launch angle for the ball will be:
tanθ = v₀sinθ/v₀cosθ
tanθ = 31.3875/36
tanθ = 0.871
θ = 41.084°
Thus, the speed v₀ of the ball will be 47.76 ft/sec, and the launch angle will be 41.084°.

when electric power is transmitted over long distance, line losses can be reduced by generating AC rather than DC voltage and by transmitting?
When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.
What is electric power?The complete question is attached to the image below.
The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.
The AC transmitted is of high voltage, and the power is low. The equation for current is given,
P = VI
The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.
Therefore, the loss is reduced by transferring high voltage and, low current AC.

at [tex]T_{3}[/tex] = 25° , [tex]P_{3}[/tex] = 0.8 MPa =8 bar
At -20°C, [tex]hf_{4}[/tex] = 173.6 KJ/Kg
[tex]hg_{4}[/tex] = 386.6 KJ/Kg
[tex]h_{4} = hf_{3} + n_{4} ( hg_{4} - hf_{4} )[/tex] = 234.49
173.6 + [tex]n_{4}[/tex] [386.6 - 173.6] = 234.49
[tex]n_{4}[/tex] = 0.285
[tex]P_{4} = P_{1} = P_{sat}[/tex] = 1.3273 bar = 0.1327 MPa
2.)
Exit specific internal energy, using table R-134a
[tex]U_{4} = uf_{4} + n_{4} (ug_{4} - uf_{4} )[/tex]
at -20°c, [tex]uf_{4}\\[/tex] = 173.65, ufg = 192.85 KJ/ Kg
