<h3>
Answer: C. Empty set</h3>
Explanation:
The first set {x | x < -3} means we're talking about numbers smaller than -3. This includes -4, -5, -6, etc
The second set {x | x > 5} means we're talking about numbers larger than 5. So things like 6,7,8,...
Combining both at the same time, we want to find a number that is both smaller than -3 and larger than 5. This is impossible as no such number exists. You can pick one or the other, but not both.
There are no solutions. Since there are no solutions, the solution set is the empty set.
Answer:
The improve in speed is 3.9334 words/min
Step-by-step explanation:
we will find speed at both occasions and then we can subtract them
First test:
total number of word =694
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
Second test:
total number of word =753
total time =15 min
we know that
speed = (total number of words)/( total time)
now, we can plug values
speed is
word/min
word/min
So, improve in speed is
word/min
