Aec= 40
Explanation because it’s a 90 degree angle and dea = 50
So 90-50=40

Answer:
i thinks the answer is the fourth, which an= 3-2(n-1)
Quadratic formulat is used when
a^2+bx+c=0
x=

Answer:
the answers have been provided below
Step-by-step explanation:
Population z score is given as (x-μ)/sd For a 32 to 35 week gestation period
μ= 2700
Sd = 900grams
x = 2225
z = (2225-2700)/900
z = -0.527
For a 40 week gestation period.
μ = 3000
Sd = 465grams
x = 2525
z = (2525-3000)/465
Z = -1.022
In answer to the question:
a. The 33-week gestation period baby weighs 0.53 standard deviations below the mean.
b. The 40-week gestation period baby weighs 1.02 standard deviations below the mean.
c. -1.022 < -0.527. the 40 weeks gestation baby weighs less.
A. The baby born in week 40 does since its z-score is smaller.
