Answer:
D. 2^7
Step-by-step explanation:
2^3 x 2^4 would equal 128. So, if you do the math for all of them:
A isn't correct because it equals 16.
B isn't correct because it equals 4096.
C isn't correct because it equals 16384.
D is correct because 2^7 is 128.

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.

So we just have to find the LCM of the denominators, then we perform the rule of addition of fraction
