They have some of the same numbers
Answer:
the first option
Step-by-step explanation:
d=m/v
must get v alone
(m)d = m/v(m)
on the right side, multiply m/v by m.
this cancels out the m's, leaving v alone.
on the left side, multiply d times m.
dm=v
Answer:
cscθ = 
Step-by-step explanation:
cscθ = 
For a unit circle, radius = 1
hence, hypotenuse = 1
opposite = y
cscθ =

use rise and run or sum else
Answer:
3.4 kg
0.06 kg
Step-by-step explanation:
Given that:
Birthweight follows a normal distribution :
Mean weighf (m) = 3.4 kg
Standard deviation (σ) = 0.6 kg
Sample size (n) = 100 new born babies
calculate the sample mean birth weight for each sample. Calculate the mean and standard deviation of the sampling distribution
The sample mean birth weight = population mean birth weight for a normal distribution according to the central Limit theorem.
Hence, sample mean birth weight = 3.4kg
Standard deviation of sampling distribution = standard error = σ/√n
0.6 / √100
= 0.6 / 10
= 0.06 kg
