A graphing calculator can do a linear regression on these points very easily. The y-intercept is 107.

_____
If you want to do this by hand, you can use the 2-point form of the equation for a line, then evaluate for x=0.
.. y = (100 -102)/(35 -25)*(x -25) +102
.. y =-2/10*(0 -25) +102
.. y = 107

  (c) 87 m^2

  (d) 180 m^2

  (e) 132 m^2

Step-by-step explanation:

(a) missing a horizontal dimension

__

(b) The difference between the bounding rectangle and the lower-left cutout is ...

  (8 cm)(7 cm) -(3 cm)(4 cm) = (56 -12) cm^2 = 44 cm^2

(c) The difference between the bounding rectangle and the center cutout is ...

  (13 m)(7 m) -(4 m)(1 m) = (91 -4) m^2 = 87 m^2

__

(d) The difference between the bounding rectangle and the two cutouts is ...

  (20 m)(25 m) -(16 m)(20 m) = (20 m)(25 -16) m = (20 m)(9 m) = 180 m^2

__

(e) The difference between the bounding rectangle and the two cutouts is ...

  (14 m)(12 m) -(12 m)(3 m) = (12 m)(14 -3) m = (12 m)(11 m) = 132 m^2

Which question is best answered by an experiment?a. Does a flipped-classroom format increase student success rates in English? b
mario62 [17]

Answer:

The correct option is d.

Step-by-step explanation:

For a question to be answered by an experiment, some conditions need to be satisfied.

An experiment must follow qualitative analysis. In a sense, an experiment must be able to be quantified. Let's take an example:

Suppose a school wants to screen candidates for an entrance level. The candidates must be of a specified number. The exam is taken. The exam scores are tabulated and distributed according to the statistical distribution. In this way, the quantitative distribution in the candidates pass mark cab be quantified.

In the question, the correct option will be d. The program can be tested quantitatively (and generating data).
