That’s how you solve complex numbers.
Answer:
28π cm
Step-by-step explanation:
hello :
the circumference is : P = 2πr r : the radius r = 14 cm
the answer is : 28π cm
The face of a three dimensional is a two dimensional. three dimensional objects are made up of two dimensional objects
1) u + 2 = 4
u = 2
2) -5 = s - 3
-2 = s
3) 5/13t = -9
t = -9 × 13/5
t = -39/5
t = -7 4/5
4) 6 = x + 2/3
x = 6 - 2/3
x = 5 1/3
5) 13 + w/7 = -18
w/7 = -18 - 13
w/7 = -31
w = -31 × 7
w = -217
6) 17 = -13 - 8x
-8x = 17 + 13
-8x = 30
x = 30/-8
x = -15/4
x = - 3 3/4

Answer:
68.268%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = $1900
σ is the population standard deviation = $200
For x = $1700
z = $1700 - $1900/$200
z = -1
Probability value from Z-Table:
P(x= 1700) = 0.15866
For x = $2100
z = $2100 - $1900/$200
= 1
Probability value from Z-Table:
P(x = 2100) = 0.84134
The probabilty of the population that has a rent price between $1700 and $2100
P(x = 2100) - P(x = 1700)
0.84134 - 0.15866
= 0.68268
Converting to percentage
= 0.68268 × 100%
= 68.268%
The percentage of the population that has a rent price between $1700 and $2100 is 68.268%
