If two of these shapes are randomly chosen, one after the other without replacement, what is the probability that the first will be a star and the second will be a square?

Step-by-step explanation:

let star be st and square be sq...

and. if two shapes are randomly chosen without replacement...

for first pick

p(st)=1/2

for second

p(sq)=1

that mean

probability of getting star at first and square at second is = p(st)*p(sq)=(1/2)*1=1/2

-1/2 +2

step-by-step explanation:

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
