Suppose that the amount, in grams, of polonium 210 present in a given sample is determined by the function defined by A(t)equ

ozzi

Answer:

The amount present in a sample of 401 grams after 25 years is $180\ g$

Step-by-step explanation:

we have

A(t) -----> the amount, in grams, of polonium 210 present in a given sample

t -----> the time in years

$A(t)=401e^{-0.032t}$

we know that

To find out the amount present in a sample of 401 grams after 25 years, substitute the value of t=25 years in the equation and solve for A(t)

For t=25 years

$A(25)=401e^{-0.032(25)}$

$A(25)=180.18\ g$

There are only 6 blue pens, 5 green pens and 8 red pens in a box.

Ronch [10]

Answer:

0.316

Step-by-step explanation:

Probability = (number of outcomes)/(total number of outcomes)

In this case,

the total number of outcomes is 6+5+8 = 19, and

the number of outcomes for getting a blue pen = 6

Hence,

P(blue) = 6/19 = 0.31578947368 ≈ 0.316
