Answer

Cluster sampling. See explanation below.

Step-by-step explanation:

For this case they not use random sampling since we are selecting people from flights. Because we select just 5 random flights.

Is not stratified sampling since we don't have strata clearly defined on this case, and other important thing is that in order to apply this method we need homogeneous strata groups and that's not satisfied on this case.

Is not convenience sampling because they NOT use a non probability method in order to select the people from the flights.

So then the only possible method is cluster sampling since we have clusters clearly defined (Passengers from the airlines), and we satisfy the condition of homogeneous characteristics on the clusters and an equal chance of being a part of the sample, since we are selecting RANDOMLY, the 5 flights to take the information.

A clock is divided into two equal parts.

(1) 1 - 6

(2) 7 - 12

When the hour hand is on (1), then the time is "after"

When the hour hand is on (2), then the time is "before"

From the attached clock, we have:

(1) The hour hand on 9

(2) The minute hand 1 unit above 9 i.e. 46 minutes

(1) implies that, the time is before 9 i.e. past 8

(2) implies that the minutes is (60 - 46) before 9 or 46 minutes after 8

In (1) and (2) above, we have two interpretations.

1: (60 - 46) minutes before 9

This gives:

14 minutes before 9

2: 46 minutes past 8

i.e. 8 : 46

you go to the nursery and buy some spring bulbs to plant in your yard you decide to buy 30 tulip bulbs and 32 daffodil bulbs for

bixtya [17]

Answer:

The cost of Daffodil bulb is $ 3.5 And

The cost of Tulip bulbs is $ 5

Step-by-step explanation:

Given as :

The total number of tulip bulbs (T) for front yard = 30

The total number of tulip bulbs for back yard = 16

The total number of daffodil bulbs (D) for front yard = 32

The total number of daffodil bulbs for back yard = 40

The amount spend on front yard = $262.00

The amount spend on back yard = $220.00

so, according to question

30 T + 32 D = $ 262

16 T + 40 D = $ 220

Or, 480 T + 512 D = 4192 ...... 1

And 480 T + 1200 D = 6600 ....... 2

Solving eq 1 and 2

Or, ( 480 T + 1200 D ) - ( 480 T + 512 D ) = 6600 - 4192

Or, 688 D = 2408

∴ D = $\frac{2408}{688}$ = $ 3.5

Put The value of D in above eq

480 T + 1200 × (3.5) = 6600

Or, 480 T = 6600 - 4200 = 2400

∴ T = $\frac{2400}{480}$ = $ 5

Hence The cost of Daffodil bulb is $ 3.5 And

The cost of Tulip bulbs is $ 5 Answer
