Answer:

Michelle exercised 150 Minutes over 5 days.

Step-by-step explanation:

Amount Exercised = half an hour per day

How many days? = 5 days

1 Hour = 60 Minutes

1/2 Hour = 60/2 Minutes = 30 Minutes

Minutes Exercised = Days x Minutes worked out in a day

5 x 30 = 150 Minutes

First, Michelle exercises for thirty minutes every day.

If Michelle exercises for 30 minutes for 5 days, this would 30 × 5.

30 × 5 = 150 minutes

Kimani works for the city and is reimbursed for his mileage when traveling for work. In order to submit his reimbursement form,
IceJOKER [234]
The mileage from the Supermarket to the Library may be calculated using Pythagorean Theorem.

The coordinates of the Library are (7,10) and the coordinates of the Supermarket are (3,7).

So, the distance requested is √ [ (7-3)^2 + (10 - 7)^2 = √[ 4^2 + 3^2 = √ [16 + 9] =

= √25 = 5

So, he runs 5 miles.

And the reimbursement will be $0.50 / mile * 5 mile = $ 2.50.

Answer: option B) $ 2.50

Definitions and Data Due Sun 02/03/2019 11:59 pm A researcher is interested in attitudes towards releasing prisoners with Alzhei
horrorfan [7]

Answer:

Step-by-step explanation:

Matching each vocabulary word with its corresponding example:

(1). All Americans = f. Population (a group of items, units or subjects under reference of study e.g. inhabitants of a region, numbers of cars in a city, workers in a factory and so on)  

(2). The proportion of all Americans who strongly agree that prisoners with life sentences who have Alzheimer's should be released = c. Parameter ( the number that summarizes some characteristic of a population)  

(3). The proportion of the 85 Americans surveyed who strongly agree that prisoners with life sentences who have Alzheimer's should be released = d. Statistic (the sample characteristic corresponding to a population parameter used when a sample is used to make statistical inference about a population)

(4). The answer-Strongly Agree' or 'Agree, or Disagree, or Strongly Disagree = b. Variable (any quality, characteristic, quantity or number that can be counted or measured)

(5). The 85 Americans who participated in the survey = e. Sample (a part or fraction of a population selected on some basis)

(6). The list of answers that the 85 Americans gave = a. Data (the pieces of information collected to be used for the analysis)

A composite figure is comprised of a square, trapezoid, and a rectangle. The square has side lengths of 10 centimeters. The trap
Evgesh-ka [11]

The area of the composite figure is 264 square centimeters, if a composite figure comprised of a square, trapezoid and a rectangle.

Step-by-step explanation:

The given is,

                   Dimensions of square has length of 10 cm

                   Trapezoid has base lengths of 8 cm and 14 cm

                   The length of the trapezoid is 4 cm

                   Rectangle has side length of 20 cm and 6 cm

Step:1

            Area of composite figure = Area of square + Area of Trapezoid

                                                                + Area of rectangle.......................(1)

Step:2

                  Formula for area of square,

                                                 A_{square} = a^{2}

                 where, a - side of length = 10 cm

                                                             =10^{2}

                                                            =100

                    Area of square, A_{square} = 100 Square centimeter

Step:3

                Formula for area of Trapezoid,

                                            A_{Trapezoid} = \frac{a+b}{2} h.......................................(2)

                    Where, a - 8 cm

                                 b - 14 cm

                                 h - 4 cm

                 From equation (2)

                                                            = \frac{8+14}{2} 4

                                                            = (11)(4)

                                                            = 44

         Area of  Trapezoid, A_{Trapezoid} = 44 square centimeters

Step:4

             Formula for area of rectangle,

                                            A_{Rectangle} =lb......................................(3)

            Where, l = 20 cm

                        b = 6 cm

           Equation (3) becomes,

                                                            = (20)(6)

                                                            = 120

            Area of rectangle, A_{Rectangle} = 120 square centimeters

Step:5

            From Equation (1),

                     A_{Composite} = 100 + 44 + 120

                                     = 264 square centimeters

Result:

            The area of the composite figure is 264 square centimeters, if a composite figure comprised of a square, trapezoid and a rectangle.
