Average=mean

Mean= sum of scores divided by number of scores

50 responders spend 45 minutes


The others spend 30 minutes


75-50= 25


So, 25 responders spend 30 minutes


50*45+25*30 divided by 75 ( because 75 is the total number of responders)


Which equals to 40 minutes

Answer:

  • domain: x ∉ {-4, 3}
  • range: y ∉ {1}
  • horizontal asymptote: y=1
  • vertical asymptote: x=3

Step-by-step explanation:

The expression reduces to ...

  \dfrac{x^2+9x+20}{x^2+x-12}=\dfrac{(x+4)(x+5)}{(x+4)(x-3)}=\dfrac{x+5}{x-3}\quad (x\ne-4)

The domain is limited to values of x where the expression is defined. It is undefined where the denominator is zero, at x=-4 and x=3. The graph of the expression has a "hole" at x=4, where the numerator and denominator factors cancel.

  • the domain is all real numbers except -4 and +3

The function approaches the value of 1 as x gets large in magnitude, but it cannot take on the value of 1.

  • the range is all real numbers except 1

As discussed in 'range', there is a horizontal asymptote at y=1. That is the value you would get if you were to determine the quotient of the division:*

  (x+5)/(x-3) = 1 + (8/(x-3)) . . . . quotient is 1

There is a vertical asymptote at the place where the denominator is zero in the simplified expression: x = 3.

  • vertical asymptote at x=3; horizontal asymptote at y=1

_____

* For some rational functions, the numerator has a higher degree than the denominator. In those cases, the quotient may be some function of x. The "end behavior" of the expression will match that function. (Sometimes it is a "slant asymptote", sometimes a higher-degree polynomial.)

Determine whether the following sampling is dependent or independent. Indicate whether the response variable is qualitative or q
NeTakaya

Answer:

1. option D

2. option A

Step-by-step explanation:

Independent samples are samples that are selected randomly so that its observations do not depend on the values other observations. Thus, this sampling is independent. The sampling is independent because an individual selected for one sample does not dictate/affect which individual is to be in the second sample.

The variable is qualitative because it is an attribute classification. A qualitative variable are variables that are not numerical. It describes data that fits into categories (personality type).
