In order of problems/numbers - 4, 3, 5, 6, 1, 2
P = m + n / -5
-5p = m + n ( because -5 was dividing with m + n so on an other side it will multiply )
-5p - m = n
<h3>
<u>Explanation</u></h3>
- Given the system of equations.

Answer:
Step-by-step explanation:

X - Heights of women aged 20 to 29: X is N(64, 2.7)
Y - Heights of men aged 20 to 29: X is N(69.3, 2.8)
a) X=6'=72"
Z=
b) Y = 72"
z=
c) 72' women can be taken as very tall but men moderately taller than average
d) Y<5'5" =65"
Z<
e) X>73"
Z>
Almost 0% can be taken
f) IQR =Q3-Q1
Z scores =
