Answer:
see explanation
Step-by-step explanation:
The complex number z = a + bi is made up of 2 parts
a ← the real part and
bi ← the imaginary part ( always with the i in it )
given z = - 60i + 80
real part = 80 and imaginary part = - 60i
The answer I believe is going to be 28.4
To simplify things, one could just use differentiation with exponents.
y= 1/(p +ke^p)= (p + ke^p)^-1
dp/dy = -1 - ke^p
Answer:
A. 0.0618.
Step-by-step explanation:
14-18= -4
-4/2.6= -1.538
Use the Z-table to find the proportion that aligns with 1.54 (round up because of the 0.008)
The intersection between 1.5 and 0.04 will be 0.0618.
Answer:
Cluster Random Sample
Step-by-step explanation:
another example should help
Example—An airline company wants to survey its customers one day. So they randomly select 5 flights that day and survey every passenger on those flights, it's a cluster random Sample
it's kinda similar
