Answer:
p*q
Step-by-step explanation:
(x + p)(x + q) = xx + px + qx + pq from binomial expansion
Answer:
B- 125
Step-by-step explanation:
c + a = 400
a = 400 - c
5c + 8a = 2825
5c + 8(400 - c) = 2825
5c + 3200 - 8c = 2825
3c = 375
c = 125
The population triples ( P × 3 ) every ten minutes...
So if ten minutes is reached there will be 1,200 bacteria.
Edited - missed the question
** The units for time should be in minutes.
P = 400 × 3^(t/10)
at t = 0 ; P = 400
at t = 10 ; P = 1,200
When P = 600
600 = 400 × 3^(t/10)
6/4 = 3^(t/10)
Log(3/2) = Log(3^(t/10))
power rule
Log(3/2) = (t/10) Log(3)
10 × Log(3/2)/Log(3) = t
3.69 minutes the population will be at 600 bacteria
Unites for time are in minutes.
Answer:
For 1 there is causationand there is correlation because they found that if people have a higher income, they will buy a more expensive plan so one cause another
the second question, there is no correlation because it doesn’t matter how many samples they provide, people still buy the same amount
