All euros have a national image on the "heads" side and a common design on the "tails" side. spinning a coin, unlike tossing it, may not give heads and tails with equal probabilities. polish students spun the belgian euro 250 times, with its portly king, albert, displayed on the heads side. the result was 150 heads. how strong is the evidence against equal proportions of heads and tails

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

a

step-by-step explanation:

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic

answer: 0.1,0.85
