Answer:

25452

Step-by-step explanation:

each term goes up by 5 so the formula is 2+5(n-1) where n is the term number

so the equation is ∑n=1 101 (2+5(n-1))

∑n=1 101 (5n-3) = 25452

Element X decays radioactively with a half life of 13 minutes. If there are 530 grams of Element X, how long, to the nearest ten

Leona [35]

Answer:

$t \approx 50.4\,min$

Step-by-step explanation:

The time constant of the element X is:

$\tau = \frac{13\,min}{\ln 2}$

$\tau = 18.755\,min$

The decay function has the following form:

$\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }$

$t = -\tau \cdot \ln \frac{m}{m_{o}}$

$t = -(13\,min)\cdot \ln \left(\frac{11\,g}{530\,g} \right)$

$t \approx 50.4\,min$

A survey questioned 4,000 community members about how a certain parcel of land should be used (for

Anuta_ua [19.1K]

Using it's concept, it is found that the sample proportion for this population is of 0.4.

The estimate of the sample proportion for a population is given by the number of desired outcomes divided by the size of the sample.

In this problem:

1,599 of those surveyed responded in favor of the park.

The sample size is of 4,000.

Hence:

$p = \frac{1599}{4000} = 0.4$

The sample proportion for this population is of 0.4.
