28 + 29 + 42 = 28 + 42 + 29 = 99
Commutative property: a + b = b + a
Answer: G and F are mutually exclusive because they cannot occur together
Step-by-step explanation:
According to the definition of mutually exclusive events,
The events which can not occur together and probability of them occurring together is 0 are known as mutually exclusive events.
The first statement gives an implication that if one happens then other happens meaning they could both still happen so it is not true.
The second statement contradict the question about being mutually exclusive events.
The third statement also is a implication that if one event occurs then other does or does not occur.
The last statement is correct one that conforms with the question and obeys the definition of mutually exclusive events.

Answer:
55.96 miles
Step-by-step explanation:
Distance = Speed X time
Car first moved east for 1 hr , distance = 40 x 1 = 40 miles
Car then moved north-east for 30 min, distance = 40 x 0.5 = 20 miles
From trigonometry,
sin 45 = 
; y = 20 sin 45 ; y= 14.14 miles
cos 45 = 
; x = 20 cos 45 ; x = 14.14 miles
using Pythagoras theorem;
= 
+ 
= 
+ 
= 3131.08
= 
z = 55.96 miles
