A radioactive substance decays at a rate of 25% every 10 years. Which equation represents the amount of the substance (S) remain
Lelechka [254]

Answer:

y = 100 * (0.75)^{30

Step-by-step explanation:

Given

a =100 --- Initial Amount

r= 25\% every 10 years

Required

The remaining amount after 300 years

To do this, we make use of:

y = a(1 - r)^T

Where

r = decay rate

T = the period of decay

In 300 years, there are 30 periods of 10 years.

i.e.

T = \frac{300}{10}

T = 30

y = a(1 - r)^T

y = 100 * (1 - 25\%)^{30

y = 100 * (1 - 0.25)^{30

y = 100 * (0.75)^{30

A number is chosen at random from the first 100 positive integers. find the probability that the number is divisible by 5. 1/10
Arlecino [84]

The probability that the number chosen is divisible by 5 is; 1/5.

<h3>What is the probability that the number chosen is divisible by 5?</h3>

It follows from the task content that the number of possible outcomes in the probability event is; 100. Additionally, the number of required outcomes is 20 as only 20 numbers are divisible by 5.

Ultimately, the required probability is; 20/100 = 1/5.
