exercise alone. Two methods of collecting data have been proposed. Method I: Recruit volunteers who are willing to participate.

Randomly assign each participant to exercise with a training partner or to exercise alone. Method II: Select a random sample of people from all the people who exercise at a community fitness center. Ask each person in the sample whether they use a training partner, and use the response to create the two groups. (a) For each method, the researchers will record the change in targeted exercise intensity for each person in the investigation. They will compare the mean change in intensity between those who exercise with a training partner and those who do not. (i) Describe the population of generalization if method I is used. Explain your answer. (ii) Describe the population of generalization if method II is used. Explain your answer.

Answer:

I) If method I is used, population of generalization will include all those people who may have varying exercising habits or routines.  They may or may not have a regular excersing habit.  In his case sample is taken from a more diverse population

II) Population of generalization will include people who will have similar excersing routines and habits if method II is used since sample is choosen from a specific population

Step-by-step explanation:

past excercising habits may affect the change in intensity to a targeted excersise in different manner. So in method I a greater diversity is included and result of excersing with or without a trainer will account for greater number of variables than method II.

Each letter in the expression shown to the right represents a digit other than zero. Different letters represent different digit
den301095 [7]

Answer:

The smallest whole number that can be the value of the expression is 2

Step-by-step explanation:

Given that the letters represent different digits, to get the smallest whole number value for the expression we have;

\dfrac{K \times A  \times N  \times G  \times A  \times R  \times O  \times O}{G  \times A  \times M  \times E}

The letters G and A cancel out from the numerator and the denominator to give;

\dfrac{K \times A  \times N   \times R  \times O  \times O}{M  \times E}

Therefore, the smallest whole number can be from 2 and above as the product of six digits is more than one times the product of two digits

If we put

K = 2, A = 3, N = 4, R = 6, O = 1, M = 9, and E = 8, we have;

\dfrac{2 \times 3  \times 4   \times 6  \times 1  \times 1}{9  \times 8} = \dfrac{144}{72} =2

Therefore, the smallest whole number that can be the value of the expression = 2.

A jar contains 5 red marbles, 10 blue marbles, 1 white marble, 6 black marbles, and 3 yellow marbles. Determine the probability
Oliga [24]

Answer:

so if we make a pie chart

there's 25 marbles

it'll be 1/25 or 4% chance

a red marble is 5/ 25 or a 20% chance

say if you replace the white on the chances of you getting red will be 24% or 6/25 chance of getting red

a circuit overloads at 1800 watts of electricity you plug a microwave oven that uses 1100 watts into the circuit write and solve
Bogdan [553]
Let w be the additional watts you can add on the circuit.

1100 + w < 1800 (write the inequality)
-1100 -1100 ( - 1100 from each side)

w < 700 (simplify)


ANSWER:
You can add up to 700 watts to the circuit, which means that you can also plug in the clock radio and the blender.


LOOK BACK:
You can check that your answer is correct by adding the numbers of watts used by the microwave oven, clock radio and blender.

1100 + 50 + 300 = 1450

The circuit will not overload because the total wattage is less than 1800 watts.
