The list of individuals from which a sample is actually selected is called the sampling frame. Ideally, the frame should list ev

ery individual in the population, but in practice this is often difficult. A frame that leaves out part of the population is a common source of undercoverage.
Suppose that a sample of households in a community is selected at random from the telephone directory.
What types of people do you think are likely to live in these households?These people will probably be underrepresented in the sample. (Select all that apply.)1.People with extra time on their hands.2.People without the extra income to keep a phone line will largely comprise the population without a phone line.3.Very busy people or those interested in maintaining privacy will largely comprise those with unlisted numbers.4.People who do not like to take surveys are likely to live in these households.

Find the value of k ​
Sholpan [36]

9514 1404 393

Answer:

  k = -2

Step-by-step explanation:

The determinant can be formed by subtracting up-diagonal products from down-diagonal products:

  (x)(x+y)(y) +(y)(x)(x+y) +(x+y)(y)(x) -(x+y)^3 -x^3 -y^3

  = 3xy(x+y) -(x^3 +3x^2y +3xy^2 +y^3) -x^3 -y^3

  = -2(x^3 +y^3)

The value of k is -2.

R interest rate?
We need to solve for r
R=(A/p)^(1/t)-1
R=(572.6÷560)^(1÷0.5)−1
R=0.0455×100

Answer:

(-6,8)

Step-by-step explanation:

2x + 9y = 60

-9x + y = 62 --> y = 9x + 62 --> 2x + 9(9x + 62) = 60 -->

2x+ 81x + 558 = 60 -->

83x + 558 = 60 -->

83x = -498 -->

x = -6 -->

y = 9(-6) + 62 -->

y = 8
