The answer for the question is 2:5
Answer: 0.5507
Step-by-step explanation:
Given : The waiting time, in hours, between successive speeders spotted by a radar unit is a continuous random variable X with a cumulative distribution function
Since , the waiting time is in hours , then we can write 12 minutes as 
hour i.e.0.2 hour.
Now, the probability of waiting fewer than 12 minutes between successive speeders is given by :-
Hence, the required probability = 0.5507

can u answer my question ****I KNOW THE ANSWER I JUST WANNA KNOW HOW U GET IT***
What percent of pure gold is in a watchcase that is 16 carats fine? In a chain that is 12 carats fine? In a ring that is 14 carats fine?
Answer:
<em>3. x = 8</em>
<em>4. lines r and s</em>
Step-by-step explanation:
3.
The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.
5x + 10 + 130 = 180
5x + 140 = 180
5x = 40
x = 8
4.
Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.
