A newborn weighs 3,874 grams at birth and 3,465 grams just prior to discharge from the hospital 2 days later. Knowing that newbo
1 answer:
Answer:
10.55%
Step-by-step explanation:
Given:
Initial weight of the new born baby = 3,874 grams
final weight of the baby = 3,465 grams
Now,
the current percentage of the weight loss will be calculated as:
Weight loss percentage = %
on substituting the respective values, we get
Weight loss percentage = %
or
Weight loss percentage = 10.55%

Answer:
a) 99.7%
b) 68%
c) 68% of organs weighs between 275 and 365 grams, so 32% of organs weighs will be less than 275 or more than 365 grams.
d) 81.5% of organs weighs between 290 grams and 365 grams.
Step-by-step explanation:
A) 99.7% of organs will be between 3 standard deviation from the mean.
So 99.7% of organs will be between 185 and 455.
B) 275 grams and 365 grams are 1 standard deviation from the mean.
From empirical rule about 68% data falls within 1 standard deviation from the mean.
So 68% of organs weighs btwn 275 grams and 365 grams.
C) Since 68% of organs weighs between 275 and 365 grams, so 32% of organs weighs will be less than 275 or more than 365 grams.
D) 230 is 2 standard deviation below the mean and 365 is one standard deviation above the mean.
According to the empirical rule, 95% of the observation lies within 2 standard deviations of the mean. Therefore 5% lies outside 2 standard deviations of the mean.
So 95%/2 = 47.5% of organs weighs between the mean and 230 grams.
According to the empirical rule about 68% data falls within one standard deviation from the mean.
so, 68%/2 = 34% of organs weighs between the mean and 365 grams.
So total = 47.5% + 34% = 81.5% of organs weighs between 290 grams and 365 grams.
Answer:
A point on the ellipsoid is (-4,2,2) or (4,-2,-2)
Step-by-step explanation:
Given equation of ellipsoid f(x,y,z) :
Parametric equations:
x=-4t-1
y=2t+1
z=8t+3
Finding the gradient of function
So, The directions vectors=(-4,2,8)
Now the line is perpendicular to plane when direction vector is parallel to the normal vector of line
So,
Substitute the value of x , y and z in the ellipsoid equation
With
x=-2(2)=-4
y=2
z=2
With
x=-2(-2)=4
y=-2
z=-2
Hence a point on the ellipsoid is (-4,2,2) or (4,-2,-2)
