Prob ( a tail in one toss) = 1/2
Prob( 3 tails in 3 tosses) = 1/2 ^3
= 1/8 (answer)
Answer:
slope=200
y-intercept=500
Step-by-step explanation:
Equation of straight line in slope intercept form is given as

here
slope=m=200/day
y-intercept=b=500

You do 80km/1hr = n/3.75
Use this proportion to find that n=300
So, he drives 800km.
Answer:
- c = 9
Step-by-step explanation:
given c = - 9 ← multiply both sides by - 1
c × - 1 = - 9 × - 1 ⇒ - c = 9
