Answer:

1. Can be Paired or Not Paired

2. Paired

3. Not Paired

Step-by-step explanation:

Two sets of observations are paired if each observation in one set has a special correspondence or connection with exactly one observation in the other data set.

1. Can be Paired or Not paired

Reason -

We might look at testing the difference of means using a two sample t-test. However, we may also try running a paired t-test.

But its used in cases where the observations are usually from the same populations at different times or through different sources etc.

Hence can't conclude that it is paired or not paired.

2. Paired

Reason -

Each record is a price of the same item from different stores.

3. Not paired

Reason -

This is again a case of testing the difference of means of two-samples (2 independent samples precisely) that are not paired.

1. Can't conclude paired or not paired

2. Paired

3. Not Paired

Two sets of observations are said to be paired if each observation in one data set has a specific connection with exactly one observation in the other data set otherwise it is unpaired.

1. Can't conclude paired or not paired because It may look at testing the difference of means using a two-sample test, But it's used in cases where the observations are from the same populations at different times or through various sources, etc.

2. Paired because each item is the price of the same item from different stores.

3. Not paired because in this case of testing the difference of means of two independent samples that are not paired.

Answer:

  2 hours 30 minutes

Step-by-step explanation:

Effort is measured in people-hours per house. Here, the effort to deliver one leaflet is ...

  (3 people)(2.5 hours)/(270 houses) = 1/36 people-hours/house

Then the number of hours (h) for 5 people and 450 houses is ...

  (5 people)(h hours)/(450 houses) = 1/36 people-hours/house

  h = (1/36)(450/5) = 2.5

It will take 2 hours 30 minutes to deliver to 450 houses.

_____

Alternate solution

The time is (assumed) inversely proportional to the number of people, so increasing the number of people from 3 to 5 multiplies the time by 3/5. The time is proportional to the number of houses, so increasing the number of houses from 270 to 450 multiplies the time by 450/270 = 5/3. The time for the second task is (3/5)(5/3) = 1 times the time for the first task.

2 1/2 hours is 2 hours 30 minutes.

Step-by-step explanation:

45 =     15 +15 +15     (3 parts of 15)

2 parts of 15  = 30

When we do this, the base of the parallelogram has length b 1 + b 2, and the height is the same as the trapezoids, so the area of the parallelogram is (b 1 + b 2)*h. Since the two trapezoids of the same size created this parallelogram, the area of one of those trapezoids is one half the area of the parallelogram

Answer:

474.43 m²

Step-by-step explanation:

The shape is composed of a rectangle and a parallelogram

Area of the composite shape = area of the rectangle + area of the parallelogram

= Length*Width + base*height

Where,

Length = 20.9 m

Width = 14.3 m

base = 20.9 m

height = 22.7 - 14.3 = 8.4 m

Area = 20.9*14.3 + 20.9*8.4

Area = 298.87 + 175.56

= 474.43 m²

The answer is 15

the equation for the relationship between x and y is,

y = 5x

A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference. Calculating the perimeter has several practical applications.

Perimeter refers to the total outside length of an object,

The equation given in the problem is

y = 5x

where

the side length of the regular pentagon in inches, x,

the perimeter of the regular pentagon in inches, y

Hence, the equation for the relationship between x and y is,

y = 5x

#SPJ2

Answer:C

Step-by-step explanation:

The expression that most adequately expresses the model would be:

C). 3 × 2/5

A fraction is described as an expression employed to denote a segment or section belonging to a larger whole.

In the given question, it can be observed that the model contains 10 parts in total with a division of 5 each into 2 parts.

Since the division of 2 is made thrice, it gives 3 × 2/5 which makes the third option the correct one.

Thus, option C is the correct answer.
