10, 8, 6, 4,…
-2 -2 -2
a(n) = a₁ + d(n - 1)
a(n) = 10 - 2(n - 1)
a(n) = 10 - 2(n) + 2(1)
a(n) = 10 - 2n + 2
a(n) = -2n + 10 + 2
a(n) = -2n + 12
Answer:
336 units
Step-by-step explanation:
When finding volume of a cube or prism multiply the its length width and height together.
4 × 7 × 12 = 336
Answer:
Needed point estimate is $372
Step-by-step explanation:
Given:
Number of houses in resident area = 121
Monthly mean car payment = $372
Find:
Best point estimate for the mean monthly car payment
Explanation:
The "best point estimate" for such average monthly automobile payment for all inhabitants of the nearby apartment complex is used as the "sample mean." In this example, a $372 sample was obtained on 121 residents.
As a result, the needed point estimate is $372.
Answer:
The population is expected to be 5515 animals in 12 years.
Step-by-step explanation:
This problem can be solved by using a compounded interest formula with a negative interest rate, since the number of animals are decreasing. We have:
final population = initial population * (1 - r)^(t)
Where r is rate of decline and t is the time elapsed. Applying the data from the question we have:
final population = 6000*(1 - 0.007)^(12)
final population = 6000*(0.993)^12 = 5514.9582 animals
The population is expected to be 5515 animals in 12 years.
