Answer:
B
Step-by-step explanation:
this is because -300 × 4.5 = is simply -1350
D, multiply the number and add the exponents.
1. 30 Hz
2. 5 Hz
3. 40 m/s
4. 400 m/s
5. .48 m/s
6. .77 m/s
7. .39 m/s
8. .625 m/s
9. 100 Hz
10. 50 Hz
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
Think: x= -6 is the equation of a VERTICAL straight line passing thru that x-value. If you meant "y equals 3, then your "solution" is the point (-6,3).
Note: Please do not type "=" preceded or followed by "equals." In this problem "equals" is OK and "=" is an unnecesssary (duplication).
