Set A represents a function because each element of its domain is paired with a unique element in the range. Set B does not represent a function because it has repeated first elements without unique corresponding second elements.
Explanation:The question asks which set of ordered pairs represents a function. A function is a special type of relation where each element of the domain (the first element in each ordered pair) is paired with a unique element in the range (the second element in each ordered pair). Analyzing option A, we see that each first element in the set A = {(1, −2), (3, −5), (5, 2), (7, 5)} is unique, which means it represents a function. However, for option B, we have repeated first elements in the set B = {(4, 2), (4, −2), (9, 3), (9, −3)}, which means it does not meet the criteria for a function as the first element, which belongs to the domain, is not mapped to a unique value in the range.

Suppose that we wish to assess whether more than 60 percent of all U.S. households in a particular income class bought life insurance last year. That is, we wish to assess whether p, the proportion of all U.S. households in the income class that bought life insurance last year, exceeds .60. Assume that an insurance survey is based on 1,000 randomly selected U.S. households in the income class and that 640 of these households bought life insurance last year
Answer:
dont know
Step-by-step explanation:
Answer:
Step-by-step explanation:
Set up hypotheses as:
[tex]H-0: p=0.60\\H_a: p >0.60[/tex]
(Right tailed test)
Sample proportion p = favourable/total = [tex]\frac{640}{1000} =0.64[/tex]
p difference [tex]=0.64-0.60 =0.04[/tex]
Sample std error = [tex]\sqrt{\frac{pq}{n} } =\sqrt{\frac{0.64(0.36)}{1000} } \\=0.0152[/tex]
Critical value for95% = 1.96
Margin of error = [tex]1.96(0.0152)\\= 0.0298[/tex]
Confidence interval for proportions
=[tex](0.64-0.0298, 0.64+0.0298)\\=(0.6102,0.6698)[/tex]
Since confidence interval does not contain 0.60 we reject null hypothesis.
At 5% significance level we can accept thta proportion >0.60
Which graph matches the equation y = -(x-2)2
The equation y = -(x-2)² represents a parabola opening downwards with a vertex at (2, 0). To find the matching graph, plot several points by calculating y for chosen x values and then connect the points to reveal the parabola's shape.
Explanation:The student is asking for the graph that matches the equation y = -(x-2)². This equation represents a parabola that opens downwards due to the negative sign in front of the parenthesis. To plot this, we'll need to create a table of values by choosing different x values, inserting them into the equation, and calculating the corresponding y values. After plotting these points, we'll see the shape of the parabola. Its vertex, the highest point on the graph due to the downward opening, will be at (2, 0) since the equation is in the form y = -a(x - h)², where (h, k) is the vertex of the parabola.
Steps for Plotting:Choose x values around the vertex (2, 0).Calculate y for each x.Plot the points on the coordinate plane.Connect the points to form a parabola.plzzz help me quick!!!

If y is 4.5 when x is 3, and y varies directly with x, find y when x is 9. 1.5 7.5 10.5 13.5
ANSWER
13.5
EXPLANATION
It was given that, y varies directly as x.
Therefore, the variation equation is of the form:
[tex]y = kx[/tex]
If y is 4.5 when x is 3, then we can substitute to find the constant of variation.
[tex]4.5 = 3k[/tex]
Divide both sides by 3;
[tex]k = \frac{4.5}{3} [/tex]
[tex]k = \frac{3}{2} [/tex]
Hence the equation becomes:
[tex]y = \frac{3}{2} x[/tex]
When x=9,
[tex]y = \frac{3}{2} \times 9 = 13.5[/tex]

The histogram shows the weekly attendance of participants in a school's study skills program. Student attendance numbers were the same during which two weeks of the workshop?
Student attendance numbers were the same during which two weeks of the workshop? B. weeks 2 and 4
Explanation:A histogram is the graphical display of data by using bars of different heights. Histograms provide a visual interpretation of numerical data by indicating the number of data points that lie within a range of values. Histogram was first introduced by Karl Pearson in 1891.
Some histograms presented with the independent variable along the vertical axis and dependent variable along the horizontal axis. The histogram attached below shows the weekly attendance of participants in a school's study skills program. In the histogram the x axis is number of weeks and y axis is number of students in attendance.
According to the histogram attached we can see that in week 1 the Student attendance was 8, in week 2 the Student attendance was 12, in week 3 the Student attendance was 15, in week 4 the Student attendance was 12, in week 5 the Student attendance was 18, in week 6 the Student attendance was 16. Hence the Student attendance numbers are the same during week 2 and 4 of the workshop. Therefore the correct option is B

Student attendance numbers were the same in week 2 and 4
What is a histogram?A histogram is a graphical representation of data that uses bars of various heights. By showing how many data points fall inside a certain range of values, histograms provide numerical data a visual interpretation. Karl Pearson initially described the histogram in 1891.
In some histograms, the dependent variable is displayed along the horizontal axis and the independent variable is given along the vertical axis. Participants in a school's study skills program's weekly attendance are depicted in the histogram below. The number of weeks is on the histogram's x-axis and the number of students present is on the y-axis.
GIVEN
The histogram that is attached shows that the student attendance for the first week was 8, for the second week was 12, for the third week was 15, for the fourth week was 12, for the fifth week was 18, and for the sixth week was 16. Thus, the student attendance figures for weeks two and four of the program are identical.

If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w.r) (x)?
The range of (w.r)(x) is all real numbers.
Explanation:The range of (w.r)(x) can be found by substituting the value of x from w(x) into r(x). So, we have:
(w.r)(x) = r(w(x)) = 2 - (x - 2)^2 = 2 - (x^2 - 4x + 4) = 6 - x^2 + 4x.
Therefore, the range of (w.r)(x) is all real numbers.
