Answer:
6
Step-by-step explanation:
-The different ways of two head and two tails in 4 tosses can be determined by drawing the sample space:
-The sample space of the four tosses is as above. Hence, they are 6 different ways to get 2 heads and 2 tails.
A) 4
∠14 & ∠12
∠11 & ∠13
∠10 & ∠8
∠7 & ∠9
vertical angles are angles directly opposite of each other and are of the same measurement.
hope this helps
Step-by-step explanation:
It is given that, Katie walks 2 ft forward and 5 ft backwards. We need to find her displacement traveled.
The difference between final position and the initial position is equal to displacement. It is the shorted path covered.
Let forward is +x and backward is -x
Initial position of Katie = +2 ft
Final position of Katie = -5 ft
Displacement = final position - initial position
= -5 - 2
Displacement = -7 ft
So, her displacement is 7 feet in backward direction.
