Answer:

This is cluster sampling.

Step-by-step explanation:

American Airlines randomly selects 110 flights during a certain week and surveys all passengers on the flights.

Answer:

Step-by-step explanation:

The triangles are not similar. Looking at the diagram, triangle STU is smaller than triangle PQR. If they are similar, it would mean that

ST/PQ = TU/QR = SU/PR

This means that there would be a scale factor. Substituting, the values, it becomes

ST/PQ = 7/9 = 0.78

TU/QR = 10/15 = 0.67

SU/PR = 8/12 = 0.67

Therefore, since

ST/PQ ≠ TU/QR ≠ SU/PR

The triangles are not similar.

Which linear functions represent a slope of 4? Check all that apply. A 2-column table with 4 rows. Column 1 is labeled x with en
Nikolay [14]

the table :

(-3,8.5) .....x1 = -3 and y1 = 8.5

(-1,5.5) ....x2 = -1 and y2 = 5.5

slope = (y2 - y1) / (x2 - x1) = (5.5 - 8.5) / (-1 - (-3) = - 3 / (-1 + 3) = -3/2

coordinate plane :

(-3,0), (2,0)

notice how u have the same y values of 0....this means u have a horizontal line where no matter what x is, y will always be 0. A horizontal line has a slope of 0. And ur y intercept is (0,0)

the linear function that is in the table contains a negative slope and also has a steeper slope then the one on the coordinate plane <===
