Julien is invited to open one of two treasure chests. he is twice as likely to open treasure chest a than treasure chest b. in treasure chest a, there are 15 gold coins. however, 60% of them are fake. in treasure chest b, there are 8 gold coins. however, 25% of them are fake. after selecting a treasure chest to open, julien randomly samples four coins. calculate the probability that julien samples an equal number of real and fake gold coins from the random sample of four.

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.

step-by-step explanation:

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

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
