T = 4. first, you can add 2 to both sides of the equation. you get 4t = 16. then, you can divide both sides by 4 to isolate t.
Answer:


And then the percentage between 24 and 40 would be 
Step-by-step explanation:
For this problem we have the following parameters given:

And for this case we want to find the percentage of lightbulb replacement requests numbering between 24 and 40.
From the empirical rule we know that we have 68% of the values within one deviation from the mean, 95% of the values within 2 deviations and 99.7% within 3 deviations.
We can find the number of deviations from themean for the limits with the z score formula we got:

And replacing we got:


And then the percentage between 24 and 40 would be 
0.64
this has to do with place value.....what place value is ur last digit (6) in ? It is in the hundredths place. so we put the 64 (without the decimal) over 100.
64/100 which reduces to 16/25. Its that simple.
Examples :
0.5....the last digit (5) is in the tenths place...so put it over 10.
5/10 reduces to 1/2.
0.225...the last digit (5) is in the thousandths place. 225/1000 reduces to
9/40
Yes the relation is a function
