Answer:
396.9 meter
Step-by-step explanation:
If a represents the acceleration,
Then according to the question,
a = -9.8 m/s²,
( acceleration = change in velocity with respect to time ),
Integrating both sides,
When t = 0 seconds, v = 0 m/s,
( velocity = change in position with respect to time ),
Integrating again,
When t = 0 , x = 0 meters,
Hence, the final equation that shows the position of the hammer after t seconds,
If t = 9 seconds,
( negative sign shows the fall ),
Therefore, it will fall 396.9 meter in 9 seconds
Which data set is the most spread from it's mean? A)14,26,24,28 B)22,16,18,36 C)22,28,20,22 D) 21,19,27,25

Answer:
b. 22, 16, 18, 36 because it has the highest number of all the choices and the second lowest. (Hope you know what I mean by that!)
Step-by-step explanation:
a. 14, 24, 26, 28 (mean is 23)
b. 16, 18, 22, 36 (mean is 23)
c. 20, 22, 22, 28 (mean is 23)
d. 19, 21, 25, 27 (mean is 23)
Answer:
Step-by-step explanation:
Given that a county park system rates its 20 golf courses in increasing
order of difficulty as bronze, silver, or gold.There are only two gold courses and twice as many bronze as silver courses.
Hence we get there are 2 gold, 12 bronze and 6 silver courses.
A) If a golfer decides to play a round at a silver or gold
= He can select any one of gold or silver
= (2+6)C1 = 8 ways
B) f a golfer decides to play one round per week for 3 weeks,first on a bronze course,then silver,then gold,
=Here no of ways = 2x12x6 = 144
(Because he can play any one of two gold, any one of 12 bronze...)
(Assuming every week all games are available)
Answer:
Clara
Step-by-step explanation:
wait nvm ignore this answer
70/10= 7
So,
77/10-70/10= 7/10
You need to subtract 7/10 from 77/10 to make 7.
I hope this helps!
