Answer:
4.5
Step-by-step explanation:
is in between and so that means that the answer is between 4 and 5 so the best answer is 4.5.
Answer: b. 30%
Step-by-step explanation:
given data:
population size (n) = 100
A1 = 0.7
A2 = 0.3
if A1 and A2 are selectively neutral, the probability that A2 would drift to fixation
= 0.3
= 30%
there is a. 30% chance that A2 would drift towards fixation.
Answer:
Step-by-step explanation:
c + f = 10 (the coach tickets + first class tickets = 10)...there is 10 people
160c + 1230f = 6950....each coach ticket is 160 and each first class ticket is 1230.....and when added, they equal 6950 (for the airfare)
c + f = 10.....c = 10 - f
160c + 1230f = 6950
sub in 10 - f for c
160(10 - f) + 1230f = 6950
distribute the 160 thru the parenthesis
1600 - 160f + 1230f = 6950
combine like terms
1600 + 1070f = 6950
subtract 1600 from both sides
1070f = 6950 - 1600
1070f = 5350
divide both sides by 1070
f = 5350/1070
f = 5 <===== she bought 5 first class tickets
c + f = 10
we found f to be 5...so sub in 5 for f and find c, the coach tickets
c + 5 = 10
c = 10 - 5
c = 5 .......and she bought 5 coach tickets
check...
160c + 1230f = 6950
160(5) + 1230(5) = 6950
800 + 6150 = 6950
6950 = 6950 (correct)....so it checks out
5 coach and 5 first class

Step-by-step explanation:
The magnitude of impulse is I = FΔ t.
What is impulse?
The concept of an impulse in it's most elementary kind could be a force integrated over a time. For a force with a relentless magnitude, we are able to notice the magnitude of the impulse by multiplying the magnitude of the force by the time that force exerted.
The direction of the impulse vector will be the direction of the force vector and the units will be a force times a time.
Impulse = Force × (final time – initial time)
Impulse = Force × Δt
I = F × Δt
Hence the magnitude of impulse is I = FΔ t.
