Based on the use of Benford's law, only B and E can be included in the solution set out of all the given values.

What is seen as Benford's Law?

Benford's Law, also known as the first-digit law, posits that the initial digits in a set of data are more likely to be smaller.

One must ascertain whether the provided values adhere to the criteria set by Benford's Law. Values like 0.5, 2.5, and 3.5 are excluded from the solution set as they do not satisfy the requirement for a whole number as the first digit.

Considering B and E, a closer examination of the graph is necessary. From the visual representation, Consequently, only the values B and Eare eligible to be part of the solution set.

A test consists of 10 true/false questions. To pass the test a student must answer at least 6 questions correctly. If a student guesses on each question, what is the probability that the student will pass the test?

Answers

Answer:

37.70% probability that the student will pass the test

Step-by-step explanation:

For each question, there are only two possible outcomes. Either the student guesses it correctly, or he does not. The probability of a student guessing a question correctly is independent of other questions. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_(n,x).p^(x).(1-p)^(n-x)$

In which $C_(n,x)$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_(n,x) = (n!)/(x!(n-x)!)$

And p is the probability of X happening.

10 true/false questions.

10 questions, so $n = 10$

True/false questions, 2 options, one of which is correct. So $p = (1)/(2) = 0.5$

If a student guesses on each question, what is the probability that the student will pass the test?

$P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10)$

$P(X = x) = C_(n,x).p^(x).(1-p)^(n-x)$

$P(X = 6) = C_(10,6).(0.5)^(6).(0.5)^(4) = 0.2051$

$P(X = 7) = C_(10,7).(0.5)^(7).(0.5)^(3) = 0.1172$

$P(X = 8) = C_(10,8).(0.5)^(8).(0.5)^(2) = 0.0439$

$P(X = 9) = C_(10,9).(0.5)^(9).(0.5)^(1) = 0.0098$

$P(X = 10) = C_(10,10).(0.5)^(10).(0.5)^(0) = 0.0010$

$P(X \geq 6) = P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) = 0.2051 + 0.1172 + 0.0439 + 0.0098 + 0.0010 = 0.3770$

37.70% probability that the student will pass the test

Order of operation and mathematical con vent ion

PEMDAS - Parenthesis, exponent, multiply, divide, add, subtract

Final answer:

In mathematics, the order of operations and mathematical conventions are vital to ensure the correct solution of equations. This includes principles like scientific notation for handling large or small numbers, and dimensional analysis for ensuring the validity of equations involving different units of measurement.

Explanation:

The order of operations and mathematical convention are fundamental in accurately solving mathematical equations or expressions. This involves following certain rules, such as the use of scientific notation or the principles of dimensional analysis, to ensure equations and operations are performed correctly and yield valid results.

Take for example scientific notation, used for expressing very large or small numbers. When multiplying two numbers expressed in scientific notation, the process is simplified: you multiply coefficients and add exponents. E.g., (3 × 105) × (2 × 109) = 6 × 1014.

Alternatively, dimensional analysis is a technique used to check the validity of equations involving mathematical operation on quantities. It works on the premise that the units of these quantities have to undergo the same mathematical operations as their numbers. This ensures consistency and coherence of dimensions and units in the expression or equation, preventing impossible situations such as adding length to time.
