Answer 1

Answer:

The table is a quadratic function

Step-by-step explanation:

Given

The attached table

Required

Tell if it is a quadratic function

The difference in the x values are uniform (i.e. difference of 1), so the following method can be applied.

(1) Subtract adjacent y values.

[tex]d_1=2 - 16 = -14[/tex]

[tex]d_2=-2 - 2 = -4[/tex]

[tex]d_3 = 4--2 = 6[/tex]

[tex]d_4 = 20 - 4 = 16[/tex]

(2) Subtract adjacent differences in (1) above

[tex]d_5 = d_2 - d_1 = -4 --14 = 10[/tex]

[tex]d_6 = d_3 - d_2 = 6 --4 = 10[/tex]

[tex]d_7 = d_4 - d_3 = 16 -6 = 10[/tex]

Notice the calculated differences in (2) are the same.

Hence, the table is a quadratic function

All parallelograms are trapezoids.
No trapezoids are parallelograms
Trapezoids do not have any parallel sides
A trapezoid has at least one pair of parallel sides.
(I’ll mark brainlist of you wrote down, not link’)

Answers

Answer:

All parallelograms are trapezoids.

No trapezoids are parallelograms.

A trapezoid has at least one pair of parallel sides

Step-by-step explanation:

1. Since a parallelogram has two pairs of parallel sides then it has at least one pair of parallel sides. Therefore, all parallelograms are also classified as trapezoids.

2. Trapezoids have only one pair of parallel sides; parallelograms have two pairs of parallel sides. A trapezoid can never be a parallelogram.

3. A trapezoid has one pair of parallel sides.

(I can't put a picture, but I would if I could)

The statement "All parallelograms are trapezoids", statement "No trapezoids are parallelograms" and statement "A trapezoid has at least one pair of parallel sides" are correct.

What is a trapezoid?

It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.

A parallelogram has at least one pair of parallel sides, since it has two pairs of parallel sides. As a result, all parallelograms are considered trapezoids.

Parallelograms have two pairs of parallel sides, whereas trapezoids have only one pair. A parallelogram can never be a trapezoid.

Thus, the statement "All parallelograms are trapezoids", statement "No trapezoids are parallelograms" and statement "A trapezoid has at least one pair of parallel sides" are correct.

Using the z-distribution, it is found that characteristics are:

a) 0.2

b) 0.0058

c) z = 2.575

d) 0.0149

e) (0.1851, 0.2149).

f) We are 99% confident the true proportion of adults who purchased something online is between 0.1851 and 0.2149.

Item a:

The point estimate is the sample proportion, hence:

[tex]\pi = \frac{789}{4750} = 0.2[/tex]

Item b:

The standard error is:

[tex]s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.2(0.8)}{4750}} = 0.0058[/tex]

Item c:

99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so [tex]z = 2.575[/tex].

Item d:

The margin of error is:

[tex]M = zs = 2.575(0.0058) = 0.0149[/tex]

Item e:

The interval is the point estimate plus/minus the margin of error, hence

[tex]\pi - M = 0.2 - 0.0149 = 0.1851[/tex]

[tex]\pi + M = 0.2 + 0.0149 = 0.2149[/tex]

The 99% confidence interval estimate of the population proportion of adults who had purchased something online is (0.1851, 0.2149).

Item f:

We are 99% confident the true proportion of adults who purchased something online is between 0.1851 and 0.2149.
