The best example of nonresponse bias from the scenario of this airline surveying customers is that Satisfied customers might be less likely to complete the survey than dissatisfied customers.

Nonresponse bias refers to a situation that arises where people are less inclined to provide feedback because their experience was different from those who did.

Satisfied customers would be less inclined to talk about their overall satisfaction than unsatisfied customers as the latter would use the opportunity to make their dissatisfaction known.

1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10

Step 1: Multiply 1 by 2:

1 x 2 = 2

Step 2: Multiply the result by 3:

2 x 3 = 6

Step 3: Multiply the result by 4:

6 x 4 = 24

Step 4: Multiply the result by 5:

24 x 5 = 120

Step 5: Multiply the result by 6:

120 x 6 = 720

Step 6: Multiply the result by 7:

720 x 7 = 5040

Step 7: Multiply the result by 8:

5040 x 8 = 40,320

Step 8: Multiply the result by 9:

40,320 x 9 = 362,880

Step 9: Multiply the result by 10:

362,880 x 10 = 3,628,800

Therefore, the product of the numbers 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 is 3,628,800.

Answer:

40

Step-by-step explanation:

Any regular polygon has exterior angles  = to 360 / number of sides.

so a 9-gon has 9 sides. The exterior angle = 360 / 9 = 40

Each exterior angle will be 40 degrees.

Try it with simpler n-gons. A triangle has 3 sides. The exterior angle is 360 / 3 = 120

A square has 4 sides. Each exterior angle is 360 / 4 = 90

Answer:

y = 20

Step-by-step explanation:

[tex]y : 28 = 5 : 7 \\ \\ \frac{y}{28} = \frac{5}{7} \\ \\ y = \frac{5 \times 28}{7} \\ \\ y = 5 \times 4 \\ \\ y = 20[/tex]

One criterion that we can use to analyze patterns is to look at the difference between consecutive terms. With this, we will see that the missing number is 361.

For the first two we have:

11 - 10 = 1

for the second and third:

21 - 11 = 10

for the fourth and third:

32 - 21 = 11

for the fifth and fourth:

53 - 32 = 21

We already can see the pattern, the n-th term can be written as:

Aₙ = Aₙ₋₁  + Aₙ₋₂

This means that the missing number, the next one, will just be equal to the sum of the two previous ones.

Then the next number is:

N = 138 + 223 = 361

Answer: C and D

Step-by-step explanation:

We need to find all the figures that are rhombuses. These figures are C and D.

The quadrilaterals C and D are those for which the diagonals cross at right angles.

Quadrilateral are closed geometrical shapes having four sides, four angles and four vertices. Some of the common quadrilaterals include rectangles, square, parallelogram and the rhombus.

Interior angles of any type of quadrilateral always sums up to 360°.

Diagonals of a quadrilateral is the straight line formed by joining opposite vertices.

For every quadrilateral, there are two diagonals.

Figure A is a rectangle. The diagonals of a rectangle bisects each other, but is not perpendicular bisector. This means that diagonals of figure A does not cross at right angles.

Figure B is a parallelogram. Properties of diagonals are almost same in rectangles and quadrilateral. Diagonals bisect each other, but is not perpendicular. So diagonals of figure B also does not cross at right angles.

Figure C is rhombus. Diagonals of a rhombus perpendicularly bisect each other. Therefore diagonals of figure C cross at right angles.

Figure D is square. Again the diagonals of a square perpendicularly bisect each other. Therefore diagonals of figure D cross at right angles.

Hence diagonals of figures C and D cross at right angles.

Answer:

r = 2/3p

A trail mix recipe asks for 4 cups of raisins for every 6 cups of peanuts.

There is proportional relationship between the amount of raisins, r (cups), and the amount of peanuts, p (cups), in this recipe.

The ratio of raisins and peanuts = 4:6  or 2:3

It would be same for every mixture.

If r cups of raisins and p cups of peanuts then their mixture ratio is r:p

Step-by-step explanation:

pls heart and give brainliest

The equation where the constant of proportionality is greater than 1 is [tex]\mathbf{p = 1.5r}[/tex], and the equation where the constant of proportionality is less than 1 is [tex]\mathbf{r = 0.67p}[/tex]

(a) Constant of proportionality greater than 1

Represent peanuts with p, and raisins with r.

So, the ratio is given as:

[tex]\mathbf{p : r = 6 : 4}[/tex]

Express as fraction

[tex]\mathbf{\frac pr = \frac 64}[/tex]

Multiply both sides by r

[tex]\mathbf{p = \frac 64r}[/tex]

[tex]\mathbf{p = 1.5r}[/tex]

(b) Constant of proportionality less than 1

In (a), we have:

[tex]\mathbf{p = 1.5r}[/tex]

Divide both sides by 1.5

[tex]\mathbf{r = \frac{1}{1.5}p}[/tex]

[tex]\mathbf{r = 0.67p}[/tex]

The graphs of [tex]\mathbf{p = 1.5r}[/tex] and [tex]\mathbf{r = 0.67p}[/tex] are the same.
