Exercise 5.16.1: Coin flips and events. About A coin is flipped four times. For each of the events described below, express the event as a set in roster notation. Each outcome is written as a string of length 4 from {H, T}, such as HHTH. Assuming the coin is a fair coin, give the probability of each event. (a) The first and last flips come up heads. Solution (b) There are at least two consecutive flips that come up heads.

Answers

Answer:

[tex](a)\ Pr = 0.25[/tex]

[tex](b)\ Pr = 0.50[/tex]

Step-by-step explanation:

Given

[tex]Flips = 4[/tex]

First, we calculate the sample size;

The coin has two possible outcomes (i.e. head or tail) and the number of flips is 4.

So, the sample size (N) is:

[tex]N = 2^4[/tex]

[tex]N = 16[/tex]

Solving (a): Probability the outcome of the first and last flip is head.

The possible outcomes for this event are:

[tex]n = \{(HHHH), (HHTH), (HTHH),(HTTH)\}[/tex]

[tex]n(n) = 4[/tex]

The probability is:

[tex]Pr = \frac{n(n)}{N}[/tex]

[tex]Pr = \frac{4}{16}[/tex]

[tex]Pr = 0.25[/tex]

 

Solving (a): Probability that the outcome of at least 2 consecutive flips is head.

The possible outcomes for this event are:

[tex]n = \{(HHHH), (HHHT),(HHTH), (HTHH),(THHH),(TTHH),(HHTT), (THHT)\}[/tex]

[tex]n(n) = 8[/tex]

The probability is:

[tex]Pr = \frac{n(n)}{N}[/tex]

[tex]Pr = \frac{8}{16}[/tex]

[tex]Pr = 0.50[/tex]

Step-by-step explanation:

For this equation: a=3, b=4, c=2

3x2+4x+2=0

Step 1: Use quadratic formula with a=3, b=4, c=2.

x= −b±√b2−4ac / 2a

x= −(4)±√(4)2−4(3)(2)  /  2(3)

x= −4±√−8  /  6

Answer:

No real solutions.

The quadratic equation 3x² + 4x + 2 = 0 does not have a real solution.

What are Quadratic Equations?

Quadratic equations are second degree polynomial equations which is of the form ax² + bx + c = 0, where a, b and c are integers.

Given quadratic equation is,

3x² + 4x + 2 = 0

Quadratic formula to find the solution is,

x = [-b ± [tex]\sqrt{b^2-4ac}[/tex]] /  2a, where [tex]\sqrt{b^2-4ac}[/tex] is called discriminant.

Here, a = 3, b = 4 and c = 2

Substituting,

x = [-4 ± [tex]\sqrt{4^2-(4*3*2)}[/tex]] /  (2 × 3)

  = [-4 ± √(16 - 24)] / 6

  = [-4 ± √(-8)] / 6

This has no real solution since the value inside the discriminant is negative.

Hence the quadratic equation has no real solution.

Solve each proportion 3/39= y/13

Answers

Answer:

[tex]y = 1[/tex]

Step-by-step explanation:

[tex] \frac{3}{39} = \frac{y}{13} [/tex]

Cross multiply

[tex]39 = 39y[/tex]

Divide by 39

[tex]y = 1[/tex]

Answer:

[tex]\boxed {\boxed {\sf y=1}}[/tex]

Step-by-step explanation:

To solve the proportion, we must solve for the variable. This is done by isolating the variable.

[tex]\frac {3}{39}= \frac {y}{13}[/tex]

The variable, y, is being divided by 13. The inverse of division is multiplication. Multiply both sides of the proportion by 13.

[tex]13*\frac {3}{39}= \frac {y}{13}*13[/tex]

[tex]13*\frac {3}{39}=y\\1=y[/tex]

Another way to solve is by cross multiplying. Multiply the 1st numerator by the 2nd denominator, then the 1st denominator and the 2nd numerator.

[tex]\frac {3}{39}= \frac {y}{13}[/tex]

[tex]3*13=39*y\\39=39y[/tex]

Divide both sides by 39 to isolate the variable.

[tex]39/39=39y/39 \\1=y[/tex]

In this proportion, y is equal to 1.

Answers

Answer:

EF is 109

DAB is 54.5

Step-by-step explanation:

Applying the central angle theorem, the correct statement would be:

Measure of minor arc EF = 109°Measure of angle DAB = 54.5°

What is the Central Angle Theorems?

The central angle theorem states that:

Measure of intercepted arc = 1/2(measure of inscribed angle)Measure of central angle = measure of intercepted arc

Thus:

Measure of minor arc EF = m∠ECF = 109°

m∠DAB = 1/2(109°) [m∠ECF = m∠BAD = 109°]

m∠DAB = 54.5°

Therefore, applying the central angle theorem, the correct statement would be:

Measure of minor arc EF = 109°Measure of angle DAB = 54.5°

Here is a simple probability model for multiple-choice tests. Suppose that each student has probability p of correctly answering a question chosen at random from a universe of possible questions. (A strong student has a higher p than a weak student.) The correctness of an answer to a question is independent of the correctness of answers to other questions. Jodi is a good student for whom p = 0.81.

Required:
a. Use the Normal approximation to find the probability that Jodi scores 77% or lower on a 100-question test.
b. If the test contains 250 questions, what is the probability that Jodi will score 77% or lower?
c. How many questions must the test contain in order to reduce the standard deviation of Jodi's proportion of correct answers to half its value for a 100-item test?
d. Laura is a weaker student for whom p = 0.76. Does the answer you gave in (c) for standard deviation of Jodi's score apply to Laura's standard deviation also?

Answers

Answer:

a) 0.8461 = 84.61% probability that Jodi scores 77% or lower on a 100-question test.

b) 0.9463 = 94.63% probability that Jodi will score 77% or lower.

c) 400 questions.

d) Yes, because the formula is the same, independently of the value of p.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

In this question:

[tex]p = 0.81[/tex]

Question a:

100 questions means that [tex]n = 100[/tex]

For the approximation, we have that:

[tex]\mu = p = 0.81[/tex]

[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.81*0.19}{100}} = 0.0392[/tex]

This probability is the pvalue of Z when X = 0.77. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.77 - 0.81}{0.0392}[/tex]

[tex]Z = 1.02[/tex]

[tex]Z = 1.02[/tex] has a pvalue of 0.8461

0.8461 = 84.61% probability that Jodi scores 77% or lower on a 100-question test.

Question b:

Now [tex]n = 250[/tex], so:

[tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.81*0.19}{250}} = 0.0248[/tex]

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.77 - 0.81}{0.0248}[/tex]

[tex]Z = 1.61[/tex]

[tex]Z = 1.61[/tex] has a pvalue of 0.9463

0.9463 = 94.63% probability that Jodi will score 77% or lower.

Question c:

The formula for the standard deviation is:

[tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

Meaning that it is inversely proportional to the square root of the sample size.

So, to reduce the standard deviation by half, the number of question must be multiplied by (2)^2 = 4.

100*4 = 400

So 400 questions.

d. Laura is a weaker student for whom p = 0.76. Does the answer you gave in (c) for standard deviation of Jodi's score apply to Laura's standard deviation also?

Yes, because the formula is the same, independently of the value of p.
