27. Amanda systematically sampled every 10th student on the cafeteria lunch line to record the amount of money spent on lunch that day. The results of her survey are listed below $2.95 $3.10 $2.85 $2.94 $3.35 $3.15 $3.15 $2.80 $2.60 $2.85 $3.15 $2.70 $3.25 $3.00 $2.95 $3.20 $2.95 $2.90 $3.00 $2.95 $2.65 $3.05 $2.75

Construct a group of frequency table and a histogram for these data. Then answer which interval contains the median of the data

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
