Lower limit of 95% confidence interval is  0.464 and upper limit of 95% confidence interval is 0.594

What is Z value of 95% confidence interval and how to find 95% confidence interval?

A Z value is a numerical measure of how far is an individual score is from the mean score, within a normal distribution.

The Z value for 95% confidence interval is Z=1.96.

Let p the  estimated proportion of people in favor of a proposition and n be the sample size, n = 225

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

Lower limit of 95% confidence interval = Z - Marignal error           

Upper limit of 95% confidence interval = Z + Marginal error

Given that in a poll of 225 randomly selected U.S. adults, 119 said they favored a new proposition,

The estimated proportion of people favored a new proposition is, p =[tex]\frac{119}{225}[/tex]

Then, p = 0.529

Marginal Error = [tex]Z\sqrt{\frac{p(1-p)}{n} } = 1.960\sqrt{\frac{0.529(1-0.529)}{225} }[/tex] = 0.065

Therefore,

Lower limit of 95% confidence interval   =0.529-0.065  = 0.464    

Upper limit of 95% confidence interval = 0.529+0.065 = 0.594

And the 95% confidence interval would be given (0.464,0.594).

Step-by-step explanation:

The domain is the set of x values and the range is the set of y values.

The range and domain for the exponential function and logistics function are Expotentioal function : Domain= (2,  infinity )

Exponential function:

An exponential function is a mathematical function of the following form: f ( x ) = a x. where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.

Exponential functions have the form f(x) = bx, where b > 0 and b ≠ 1. Just as in any exponential expression, b is called the base and x is called the exponent. An example of an exponential function is the growth of bacteria. Some bacteria double every hour.

In exponential notation, a number usually is expressed as a coefficient between one and ten times an integral power of ten, the exponent. To express a number in exponential notation, write it in the form: c × 10n, where c is a number between 1 and 10 (e.g. 1, 2.5, 6.3, 9.8) and n is an integer (e.g. 1, -3, 6, -2

Definition of logarithmic function: a function (such as y = log x or y = ln x) that is the inverse of an exponential function (such as y = ax or y = ex) so that the independent variable appears in a logarithm.

When b > 0 and b 1, an exponential function has the form f(x) = bx. The base is b, and the exponent is x, just like in any exponential expression. The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour.

Equating the expressions for y gives ...

  -2x +7 = 5x -7

  14 = 7x . . . . . . . add 7+2x

  2 = x . . . . . . . . . divide by 7

  y = 5(2) -7 = 3 . . find y from the second equation

The solution is (x, y) = (2, 3).

The number of standard deviations from the mean that include all

From the gathering of information, we will see that the minimum worth is $19.95 and also the most worth is $29.95.

She should report the Mean because it will be greater than the Median.

Let's start with the example from before. Imagine you teach a class with 20 students, and they take a test with 20 multiple choice questions about the Revolutionary War. Imagine that the grades you get back from scoring their tests look like this:

So you can see we have student #1 through student #20, and you can see that the scores range quite a bit. Looking at these scores you can see that one student, student #1, got a perfect score of 20 out of 20. Many students got scores somewhere in the middle, with five students getting half of the questions right - that would be a score of 10 out of 20. A few of the students did pretty well, only missing a few questions, While a few students did pretty badly but at least got a few of the questions right.

Let's say the principal of your school wants a quick summary of how your students did on their test. How would you summarize the results? The most common type of statistic, in either the context of the classroom assessment or in laboratory research projects, is statistics of summary. There are various types of Statistics of summary, but in general their purpose is to quickly give an general impression of the overall trend in results. So, just like you'd guess, based on the term Statistics of summary, these statistics just give you a ballpark idea of what happened on the test.

The most well-known statistic of summary is called the mean, which is the term we use for the arithmetic average score. When most people use the term 'average score,' what they're really referring to, technically, is what we call the mean. How do we calculate the mean? We simply add up all of the individual results, get the total, and then divide by the number of students in the class. In our example, you can see how this would look on the screen. If you add up the scores of 20 + 17 + 16 and so on through all 20 students, you get a total score of 210. You divide 210 by 20 (the number of students), and you get a mean of 10.5. You can see that this score, 10.5, is a pretty representative score of the middle score for this class, so it works nicely as a summary.

Using the probability concept, it is found that:

a) The probability is 0.682.

b) The probability is 0.578.

c) A student given a $1 bill is more likely to have spent the money than a student given four quarters.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For item a, we have that out of the 44 students that were given four quarters, 30 students spent money purchasing gum, hence:

p = 30/44 = 0.682.

The probability is 0.682.

For item b, we have that out of 45 students that were given a $1 bill, 26 kept the money, hence:

p = 26/45 = 0.578.

The probability is 0.578.

Hence the correct option for item c is:

A student given a $1 bill is more likely to have spent the money than a student given four quarters.

Answer:

x=48, y=12

Step-by-step explanation:

Angles in a triangle add to 180°.

In triangle AOD,

[tex]90+x-6+x=180 \\ \\ 2x-6=90 \\ \\ 2x=96 \\ \\ x=48[/tex]

Similarly, in triangle COB, y=12.

The fifth angle measure of the polygon is 112°

Since a pentagon is made up of three triangles, its total angles are 3 * 180 * 540. The following formula may be used to get the pentagon's total interior angles: We are aware that the interior angle sum of a polygon with n sides is equal to (n - 2) 180°.

Let the missing angle be x.

The sum of the angles of pentagon is 540°

540 = 100 + 103 + 111 + 114 + x

540 = 428 + x

The total number of student present in the class is 15.

One-third of the students choose to work on an essay.

Let

x = the total number of student in the class

Therefore,

student that takes essay = 1 / 3 x

One-half of the remaining students choose to read.

Therefore, the expression is as follows

student that choose to read = 1 / 2(x - 1 / 3 x)  = 1 / 2( 3x - x/ 3) = 1 / 2(2 / 3 x) = 2 / 6 x = 1 / 3x

The remaining 5 students work on vocabulary.  Therefore, the expression is as follows:

Student that works on vocabulary = x - 1 / 3 x - 1 / 3 x

5 =  x - 1 / 3 x - 1 / 3 x

5 = 3x- x - x / 3

5 = x / 3

x = 15

Therefore,

the student present in the class = 1 / 3 (15) +  1 / 3(15) + 5

the student present in the class = 5 + 5 + 5

the student present in the class = 15

break down the equations into parts and use simultaneous equation method to solve it

Answer:

Step-by-step explanation:

ihe

1. The equation is: y = 35x + 50

2. The significance of the slope is: A. The ant travels at an average of 35 meters per minute.

3. Distance would be 490 meters.

4. Number of minutes will be: 16.

Given that x = minutes, and y = distance, then we would have the following coordinates:

(2, 120)

(6, 260)

1. The slope (m) = change in y / change in x = 260 - 120 / 6 - 2

Slope (m) = 35

Substitute m = 35, and (x, y) = (2, 120) into y = mx + b to find b

120 = 35(2) + b

120 = 70 + b

120 - 70 = b

b = 50

Substitute m = 35 and b = 50 into y = mx + b to write the equation

y = 35x + 50

2. The slope of the graph 35.

The significance of the slope is: A. The ant travels at an average of 35 meters per minute.

3. When x = 14, we have:

y = 35(14) + 50

y = 490

Distance would be 490 meters.

4. Substitute y = 610 into y = 35x + 50

610 = 35x + 50

610 - 50 = 35x

560 = 35x

560/35 = 35x/35
