A company needs to replace 27 out of 45 desks in their office. What percent of the desks need to be replaced?

sleet_krkn [62]

60%

Solve by creating a proportion
27/45 = x/100

Cross multiply to get 2700=45x

Divide 45 on both sides to get x=60

Solnce55 [7]

Answer:

There were total 4 samples collected and each sample had a sample size of n = 100.

Step-by-step explanation:

We are given the following information in the question:

Collection of samples:

$1^{st}\text{ sample was done in January with a sample size n = 100}$

$2^{nd}\text{ sample was done in March with a sample size n = 100}$

$3^{rd}\text{ sample was done in June with a sample size n = 100}$

$4^{th}\text{ sample was done in September with a sample size n = 100}$

Hence, there were total 4 samples collected and each sample had a sample size of n = 100.

The differential equation in Example 3 of Section 2.1 is a well-known population model. Suppose the DE is changed to dP dt = P(a

LuckyWell [14K]

Answer:

Decreases

Step-by-step explanation:

We need to determine the integral of the DE;

$dP/dt=P(aP-b)$

$dP=P(aP-b)dt$

$1/(dP^2-bP)dP=dt$

We can solve this by integration by parts on the left side. We expand the fraction 1/P²:

$1/(d-b/P)\cdot{P^2} dP$

let

$u=d-b/P$

$du/dP=b/P^2$

$dP=$ $\int\limits {P^2/b} \, du$

$P=lnu/b$

Substitute u in:

$P=ln(d-b/P)/b$

Therefore the equation is:

$ln(d-b/P)/b=t$

We simplify:

$d-b/P=e^b^t$

$P=b/(d-e^b^t)$

As t increases to infinity P will decrease
