Step-by-step explanation:
Implicit differentiation
chain rule is important here
I'll show the steps partially
now evaluate for (-2,2)
x=-2 and y=2
that's it, simplest form
Answer:
1. z = -1.91429
The z score tells us that the head circumference of the girl with the down syndrome ( 44.5 cm) is 1.91429 standard deviations below the mean or average head circumference
2. 2.7792%
Step-by-step explanation:
1. Relative to the WHO data, what is this girls z-score?
z score formula is:
z = (x-μ)/σ, where
x is the raw score = 44.5 cm
μ is the population mean = 47.18cm
σ is the population standard deviation = 1.40cm
z = 44.5 - 47.18/1.40
z = -1.91429
What does the z score tell us?
The z score tells us that the head circumference of the girl with the down syndrome ( 44.5 cm) is 1.91429 standard deviations below the mean or average head circumference
2. Using the WHO data in a normal model, what percentage of the girls has a head circumference that is smaller than the girl with Down's Syndrome?
z score = -1.91429
Probability value from Z-Table:
P(z =-1.91429) = P(x<44.5) = 0.027792
Converting to percentage = 0.027792 × 100
= 2.7792%
Answer:
A= -u²n²t²s²arme²
Step-by-step explanation:
Evaluate m, then set it equal to 15.
=15
Evaluate s, the set it equal to 2.
=2
Simplify unitsareminutes.
−u²n²t²s²arme²
List all the solutions.
BN•N=BN²
m=15 ==15
s=2 2==2
84+92+87+104=367
500-367=133
