Step-by-step explanation:
Work done = Force × displacement
= 350 × 40
=14000J
3a + b = 54...when b = 9
3a + 9 = 54
3a = 54 - 9
3a = 45
a = 45/3
a = 15 <===
Answer: Experimental Probability
Step-by-step explanation:
Theoretical Probability is the theory behind probability. Experimental (empirical) probability is probability calculated during experiments, direct observation, experience, or practice. The empirical probability, relative frequency, or experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.

400 800 1200 1600 2000 is anwser
9^4 + 3^3
= 9•9•9•9 + 3•3•3
= 6,561 + 27
= 6,588
