Abag contains 6 white marbles and 4 black marbles. you pick out a marble, record it’s color, and put the marble back in the bag. if you repeat this process 35 times, about how many times do you expect to remove a white marble from the bag?
me !

21

Step-by-step explanation:

The probability that you get a white marble is

P(white) = white/total

              = 6/10

             = 3/5

The number of white marbles drawn = P (white) * number drawn

(since there is replacement)

white marbles = 3/5 *35 = 21

You should expect 21 white marbles

The probability of picking out a white marble is

(number of white marbles) / (number of all marbles)

= 6/10

= 60 % .

If the 35 draws break exactly according to the probability, then you' expect to get white marbles

(60%) of (35 draws)

= (0.6) x (35 draws)

= 21 times

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
