Could you please give more information, or word your question a little better?
Answer:
They have the same y-intercept of -6.
.6 would be your answer. You just substitute in.
Answer:
84%.
Step-by-step explanation:
Let X be the time in minutes for a student chosen at random to finish the test. .
The probability that a student chosen at random finishes the test in less than 48 minutes will represented as
.
<h3>Method 1: technology</h3>
Evaluate the cumulative normal probability on a calculator, where
- The lower bound is 0,
- The upper bound is 48,
- The mean ,
- The standard deviation
.
<h3>Method 2: z-score table</h3>
.
.
Look up the entry that corresponds to on a z-score table: 0.8413.
In other words,
.
Answer:
The distance traveled in this time downstream is 1,000 ft
Step-by-step explanation:
In order to calculate how far downstream is she swept when she reaches the opposite bank we would have to make the following calculation:
distance traveled in this time downstream=speed*time to reach other side
speed=6 ft/s
time to reach other side=500/3
time to reach other side=166.66 s
Therefore, distance traveled in this time downstream = 6*166.66
distance traveled in this time downstream= 1,000 ft
The distance traveled in this time downstream is 1,000 ft
