Answer:
2
Step-by-step explanation:
Is it just x=b-cd
If so
cd=b-x
÷d. ÷d
C=b-x/d
Answer:
-3
Step-by-step explanation:
m=y2-y1/x2-x1
m=-6-3/-1-(-4)
m=-9/3
m=-3
Answer:
0
Step-by-step explanation:
given that we roll a fair die repeatedly until we see the number four appear and then we stop.
the number 4 can appear either in I throw, or II throw or .... indefinitely
So X = the no of throws can be from 1 to infinity
This is a discrete distribution countable.
Sample space= {1,2,.....}
b) Prob ( 4 never appears) = Prob (any other number appears in all throws)
=
where n is the number of throws
As n tends to infinity, this becomes 0 because 5/6 is less than 1.
Hence this probability is approximately 0
Or definitely 4 will appear atleast once.
To solve this problem, we must first convert the distance
into miles:
distance = 60 ft (1 mile / 5280 ft) + 6 inches (1 foot /
12 inches) (1 mile / 5280 ft)
distance = 0.0114583 mile
To calculate for time:
time = distance / speed
time = 0.0114583 mile / (90 miles / 3600 seconds)
time = 0.458 seconds
<span>time = 0.46 seconds</span>
