Jose surveyed the length of TV commercials (in seconds). Find, to 3 decimal places, the experimental probability that a randomly chosen TV commercial will last:
Length Frequency
0-19 17
20-39 38
40-59 19 20 to 39 seconds.
60+ 20 to 4
Here is my anwer:
experimental probability = relative frequency =
Total frequencies = 17 + 38 +18 + 4 = 78
P(20 to 39s) = 38/78 ≈0.487
The bat fit diagonally across the bottom of the suitcase.
Solution:
Length of the suitcase = 20.5 inches
Width of the suitcase = 29 inches
Using Pythagorean theorem,
Taking square root on both sides, we get
Diagonal of the suitcase = 35.5 inch
Length of the base ball bat = 33 inch
35.5 > 33
Since the diagonal of the suitcase is greater than length of the baseball bat,
The bat fit diagonally across the bottom of the suitcase.
Mia gives $80 as tip to the movers.

The moving company charged $500 for its service.
Suppose, the amount of tip is dollar, which is 16% of the total charge.
So, the equation will be.....
