!ebony owns a number of shops. she keeps careful records about which products sell best and notes ideas about how to increase sales. one of ebony’s stores is a small shop that sells hats and caps. ebony held a contest for the best hat design, planning to award a camera to the designer with the winning entry. she received numerous entries and narrowed her choice for first place to two designs; however, she couldn’t decide between dawnie’s design and betty’s design. since ebony couldn’t decide which of these two designs was better, she decided to hold a random drawing to determine the winner. ebony planned to randomly pull chips from a bag. she put 20 chips in the bag: 10 gold chips and 10 silver chips. ebony says she will pull 2 chips out of the bag, one at a time. if the 2 chips are the same color, she will give the camera to betty. if the 2 chips are different colors, she will give the camera to dawnie. is this method fair? if it is not, explain who has an advantage in the drawing and how great the advantage is. show your work and explain your reasoning.

No. The method is not fair.

The probability of pulling a gold or a silver for the first time is 1/10. The probability of getting the same color the second time is 1/9. The probability of getting a different color on the second pullout is still 1/10. Therefore, the chance that same  colors will be pulled out is higher than that of different colors.  Betty  has an advantage in the drawing by 1.1%.

Solution:

Probability of same color:

1/10+1/9

9/90+10/90

21.1%

Probability of different colors

1/10+1/10

2/10

20%

21.1%-20%=1.1%

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
