Answer:
≈0.487
Step-by-step explanation:
I think this is your full question right?
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
Answer:
y = 10 + 2.50h
$25
Step-by-step explanation:
first the equation is written as such because she pays $10 no matter how many hours she rides. She also pays 2.50 for each hour so use h as the variable to define number of hours she rides the bike.
since equation is y = 10 +2.50h
and h = 6 hours, substitute and find the total cost
y = 10 + 2.50(6)
= 10 + 15
= $25

I don't think theses are right but they are just a guess
Answer:
254.5 Inches Cubed
Step-by-step explanation:
Formula for Finding the Volume of a Cylinder: 
The radius is 3 inches.
The height is three times the radius.
Multiply the radius by three to get the height.
The height is 9 inches.
Use the formula to find the volume.
The exact volume is 81
inches cubed.
≈ 254.47
254.47 ≈ 254.5
The volume of the cylinder should be about 254.5 inches cubed.
