A dentist gives each patient a toothbrush after his or her visit. The toothbrushes come in 5 different colors, and they are chosen at random to give to the patients. The chart shows the number of each color toothbrush given to the last 50 patients to visit the dentist's office. Fill in the table with the probability of each event occurring. Toothbrush Color Number of patients who received it Observed Probability Red 9 a. Blue 7 b. Green 15 C. Yellow 11 d. 8 e. Orange

Step-by-step explanation:

Given the following :

Colors of toothbrush = 5

Number of patients = 50

Color ___Number of patient

Red 90.18

Blue 70.14

Green _ __15 0.30

Yellow ___ 110.22

Orange ___8 0.16

Probability of each event:

Probability = (required outcome / Total possible outcomes)

Hence,

P(Red) = 9/50 = 0.18

P(blue) = 7/50 = 0.14

P(green) = 15/50 = 0.3

P(yellow) = 11/50 = 0.22

P(orange) = 8/50 = 0.16

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
