Element X decays radioactively with a half life of 11 minutes. If there are 870 grams
exis [7]

Answer:

27.5 minutes

Step-by-step explanation:

Using,

R/R' = 2ᵃ/ᵇ------------------ Equation 1

From the equation,

R = mass of Element X before radioactive decay, R' = mass of element X after radioactive decay, a = Time taken, b = half life.

Given: R = 870 grams, R' = 154 grams, b = 11 minutes.

Substitute these values into equation 1

870/154 = 2ᵃ/¹¹

(870/154)¹¹ = 2ᵃ

Solve for a

2ᵃ = (5.649)¹¹

2ᵃ = 187061.26

Taking the logarithm of both side,

Log2ᵃ = Log(187061.26)

⇒ a = log(187061.26)/log2

a = 8.272/0.301

a = 27.5 minutes

What shows the possible outcomes of a random experiment and the probability of each outcome?
Katarina [22]

The possible outcomes of a random experiment and the probability of each outcome is called "a Probability Distribution."

<h3>What is a Probability Distribution?</h3>

A probability is a statistical formula that indicates all of the potential values and probability distributions for a random variable within a specified range.

Some characteristics regarding the Probability Distribution are-

  • The range will be bounded by the minimum and greatest possible values, but the precise location of the possible value just on probability distribution relies on a number of factors.
  • These variables include the mean (average), standard deviation, skewness, & kurtosis of the distribution.
  • Although other regularly used probability distributions exist, the normal distribution, called "bell curve," is perhaps the most common.
  • Typically, the technique of generating data for a phenomenon will influence its probability distribution. This is known as the probability density function.
  • Likelihood distributions can also be used to generate cumulative distribution functions (CDFs), that cumulatively build up the probability of occurrences and always begin at zero and end at 100%.
