Katrina owns a sandwich shop. she wants to know if she can sell more chicken sandwiches if they are prepared with a special sauce. katrina sells regular chicken sandwiches on a random sample of 10 days and she sells sandwiches with the special sauce on a random sample of 10 days. she collects data on the number of sandwiches sold each day. regular sandwiches: 15, 17, 22, 22, 25, 15, 18, 20, 25, 24 special sauce: 18, 20, 35, 28, 18, 20, 20, 30, 24, 35 the means are 20.3 and 24.8 respectively, for a difference of 4.5. katrina wants to know if this is significant or if it could be caused by chance. to find out, she re-randomizes the results 15 times and finds the differences of the means. the dot plot shows the data. what is the best conclusion for katrina to make based on the data?

The difference of 4.5 is significant because the re-randomizations show that it is outside the range of what could happen by chance.

( I took the quiz )

Step-by-step explanation:

b i think

step-by-step explanation:

not really sure

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
