Answer:
131
Step-by-step explanation:
Whee
remember
multiply both sides by 2^x
minus 3(2)^x from both sides
we can use the quadratic formula
use u subsitution where u=2ˣ
use quadratic formula
and
solve
subsitte and solve
u=2ˣ
take ln of both sides
divide both sides by ln(2)
for other one
take ln of both sides
divide both sides by ln(2)
so
and
those are the 2 solutions

Answer: 0.6812
Step-by-step explanation:
Let p be the population proportion of trees are infested by a bark beetle.
As per given: p= 12%= 0.12
Sample size : n= 1000
Number of trees affected in sample = 1000
Sample proportion of trees are infested by a bark beetle. =
Now, the z-test statistic :
So,
Hence, the value of the z-test statistic = 0.6812 .
