Answer:

.701

Step-by-step explanation:

The reason for the option chosen is because the coefficient is closer to 1 which is the standard for correlation and also, the answer is rounded off to three decimal places as requested in the question.

Solution 1

Answer:

Option D is correct.

That is,

Randomly generate an integer from 1 to 7 two times, and the probability is (1/7) ^2

Step-by-step explanation:

The probability of having birthday on a particular day of a week for anyone is 1/7. That is, 1 day out of the 7 days in a week.

Then for another person to have birthday on that same day is mathematically given as

(1/7) × (1/7) = (1/7)²

And this corresponds to option D. Therefore option D is the statement that best describes the use of a simulation to predict the probability that two randomly chosen people will both have their birthdays on a Monday.

Hope this helps!

Question
If there were 5 million births in a particular country and 3 comma 375 sets of naturally occurring​ triplets, what is the experimental probability of having triplets​ naturally?
Solution 1

Answer:

Probablity =P=6.75*10^-^4

Step-by-step explanation:

The experimental probability can be defined as the ratio of the number of times any particular event has occurred to the total number of times that event has taken place.

Experimental probability = P = No. of event occurrences / total number of occurrences.

In our question statement,

No of naturally occurring triplets are = 3375

Total number of births = 5 million = 5,000,000

Putting values in equation.

P=3375/5000000

P = 0.000675\\P=6.75*10^-^4

Solution 2

Answer: 6.75

Step-by-step explanation:

You just divide by 3,375/500,000 and get 6,75

Question
Three distinct integers are chosen at random from the first 20 positive integers. Compute the probability that: (a) their sum is even; (b) their product is even.
Solution 1

Answer:

Step-by-step explanation:

There are first 20 positive integers 1,2...20. Three distinct integers are chosen at random.

Total no of ways of drawing 3 integers = 20C3 = 1140

To  Compute the probability that: (a) their sum is even

a) Sum can be even if either all 3 are even or 1 is even and 2 are odd.

There are in total 10 odd and 10 even.

Ways of sum even = 10C3 + 10C2 (10C1)\\= 120+45(10)\\= 570

Prob = \frac{570}{1140} =0.50

b) their product is even

Here any one should be even or both

SO no of ways are

=10C2 +10C2(10C1)\\= 45 +450\\=495

Prob = \frac{495}{1140} =0.4342

Question
Given a data​ set, how do you know whether to calculate sigma or​ s? Choose the correct answer below. A. If the given data set contains a large number of​ entries, then s is calculated. If the data set contains a small number of​ entries, then sigma is calculated. B. When given a data​ set, one would have to determine if it represented the population or if it was a sample taken from the population. If the data are a​ population, then sigma is calculated. If the data are a​ sample, then s is calculated. C. When given a data​ set, one would have to determine if it represented the population or if it was a sample taken from the population. If the data are a​ population, then s is calculated. If the data are a​ sample, then sigma is calculated. D. If the given data set contains a large number of​ entries, then sigma is calculated. If the data set contains a small number of​ entries, then s is calculated.
Solution 1

Answer:

B

Step-by-step explanation:

S is the sample standard deviation, it is calculated when the observations represent a sample of the population. sigma is the population standard deviation, it is calculated when de observations are the whole population.

Question
Which of the following variables are qualitative and which are quantitative? If the variable is quantitative, then specify whether the variable is discrete or continuous. a. Points scored in a football game. Qualitative Quantitative; discrete Quantitative; continuous b. Racial composition of a high school classroom. Qualitative Quantitative; discrete Quantitative; continuous c. Heights of 15-year-olds. Qualitative Quantitative; discrete Quantitative; continuous
Solution 1

Answer:

a) Quantitative; discrete  

b) Qualitative

c)  Quantitative; continuous                        

Step-by-step explanation:

Quantitative and Qualitative:

  • Qualitative variables are the non-parametric variables.
  • Quantitative variables are the variables whose values are expressed in the form of number.
  • Qualitative is information about a variable where as quantitative describes the variable with the help of values.

Discrete and Continuous:

  • Quantitative variables whose values are expressed in the form of whole numbers are discrete variable.
  • Discrete variable cannot take all the values of an interval. They are counted not measured.
  • Quantitative variable whose values can be expressed in the form of decimals are continuous variable.
  • Continuous variable take all the values within interval. They are measured not counted.

a. Points scored in a football game.

Since the points are expressed in numerical. Thus, they are quantitative variable. Since points are always expressed in whole numbers and are always counted it is a discrete variable.

b. Racial composition of a high school classroom

This will include the categorical values and not expressed as numerical. Thus, it is qualitative variable.

c. Heights of 15-year-olds.

These values will be expressed with the help of numerical and can take any value within an interval. Also, height is always measured and not counted. Thus it is a continuous variable.

Question
the sales tax in bills state is 6% bill bought a scion on having a sales tax of $820 what was the cost of the car round to the nearest dollar
Solution 1
Tax paid = $820

Let the value = x.

Tax = 6%

6% of x = 820

(6/100)x = 820

0.06x = 820

x = 820/0.06

x ≈ `13666.67

Cost ≈ $13 666.67
Question
Hayden earns $9.50 per hour as a lifeguard.He earns a bonus of $50.00 for taking a training course.How many hours must he work to earn at least $300.00
Solution 1

Answer: he must work for at least 26.32 hours

Step-by-step explanation:

Let x represent the number of hours that Hayden works as a life guard.

Hayden earns $9.50 per hour as a lifeguard. This means that the amount that he earns for working for x hours would be

9.5x

He earns a bonus of $50.00 for taking a training course. If he takes this bonus cost, the amount that he would earn for working for x hours is

9.5x + 50

Therefore, the number of hours that he must work to earn at least $300.00 would be

9.5x + 50 ≥ 300

9.5x ≥ 300 - 50

9.5x ≥ 250

x ≥ 250/9.5

x ≥ 26.32

Solution 2

Answer:

Step-by-step explanation:

Its 27 even tho it goes to 26.32 rounded it to 27

Question
Completing the square: find the value of c that completes the square. 1.) x 2.) 3.)
Solution 1

Answer:

Step-by-step explanation:

Key to this method is remembering that

(a+b)^2 = a^2 + 2ab + b^2

So, if you divide the coefficient of x by 2 and square it, that will complete the square. With that in mind, things are easy.

6/2 = 3, so add 3^2 = 9

x^2+6x+9 = (x+3)^2

So, c=9

Similarly, for the other two,

c = (\frac{-34}{2} )^2 = (-17)^2 = 289

You don't really have to worry about the sign, since squaring will always make it positive

(\frac{25}{13}) ^2 = \frac{625}{169}
