dentify which type of sampling is used: random, systematic, convenience, stratified, or cluster. To determine customer opinio

Rudik [331]

Answer:

The type of sampling used is the Cluster sampling technique.

Step-by-step explanation:

- Random Sampling

In random sampling, each passenger would have an equal chance of being surveyed. If this particular scenario wanted to use random sampling, they would have used computer generated random passenger numbers and surveyed them, not just passengers all on the same bus picked randomly.

- Systematic sampling is easier than random sampling. In systematic sampling, a particular number, n, is counted repeatedly and each of the nth passengers is picked to be sampled.

- Convenience Sampling

This is the worst sampling technique. It is also the easiest. In Convenience sampling, the surveyor just surveys the first set of passengers that they find.

- Stratified Sampling

Stratified sampling divides the population into groups called strata. A sample is taken from each of these strata using either random, systematic, or convenience sampling.

- Cluster sampling

Cluster Sampling divides the population into groups which are called clusters or blocks (the different buses). The clusters are selected randomly, and every element in the selected clusters is surveyed (each passenger on the selected buses, is surveyed!). Evidently the answer to the question!

What is the area of the circle?

AlexFokin [52]

Answer:

530.93

Step-by-step explanation:

area of a circle = πr²

where r = radius

here we are given the diameter

to convert to radius , we divide by 2

so radius = 26 / 2 = 13

so we have A = πr²

==> plug in r = 13

A = π13²

==> evaluate exponent

A = 169π

==> multiply 169 and π

A = 530.93 ( approximately )

Which expression has a value of 15 when n = 7? 43 minus 5 n 3 n minus 5 6 n minus 28 19 minus StartFraction 28 Over n EndFractio

andrey2020 [161]

Answer:

$19-\dfrac{28}{n}$ is the expression with value of 15 when n = 7.

Step-by-step explanation:

To find the expression whose value is 15, substitute the value of n = 7 in each given expression.

Expression 1:

$43-5n$

Substituting the value of n,

$43-5\left(7\right)$

Simplifying,

$43-35=8$

Since the value of the expression is 8 which is not equal 15.

Hence expression $43-5n$ does not have value of 15 when n = 7.

Expression 2:

$3n-5$

Substituting the value of n,

$3\left(7\right)-5$

Simplifying,

$21-5=16$

Since the value of the expression is 16 which is not equal 15.

Hence expression $3n-5$ does not have value of 15 when n = 7.

Expression 3:

$6n-28$

Substituting the value of n,

$6\left(7\right)-28$

Simplifying,

$42-28=14$

Since the value of the expression is 14 which is not equal 15.

Hence expression $6n-28$ does not have value of 15 when n = 7.

Expression 4:

$19-\dfrac{28}{n}$

Substituting the value of n,

$19-\dfrac{28}{7}$

Simplifying,

$19-4=15$

Since the value of the expression is 15 which is equal 15.

Hence expression $19-\dfrac{28}{n}$ has the value of 15 when n = 7.

Pls help me and i will know if it is wrong

DENIUS [597]

9514 1404 393

Answer:

90 miles

Step-by-step explanation:

Let d represent the distance to Grandma's house.

The speed going was ...

speed = distance/time

speed = d/2

The speed coming home was ...

speed = d/2.25

The difference of these speeds is 5 miles per hour:

d/2 -d/2.25 = 5

2.25d -2d = 5(4.50) . . . . . multiply by 4.50

0.25d = 22.5 . . . . . . . . . . .simplify

d = 90 . . . . . . . . . . . . . . . . multiply by 4

Grandma's house is 90 miles away.
