i need with statistics/math

Part A

"A school did a survey among 100 students" means we have 100 people total, so I = 100 which goes in the lower right hand corner of the table. This is the grand total.

-------------

"out of 77 people who liked football, 48 also liked baseball". So this means C = 77 and A = 48. Because of this, we know...

A+B = C

48+B = 77

B = 77-48

B = 29

Therefore 29 people like football, but do not like baseball.

-------------

"There were 65 people who liked baseball" means G = 65 which is the total for the "baseball" row.

Use A = 48 and G = 65 to find the value of D

A+D = G

48+D = 65

D = 65-48

D = 17

We have 17 people who like baseball but do not like football.

-------------

If G = 65 and I = 100, then H = I-G = 100-65 = 35

Similarly, if B = 29 and H = 35, then E = H-B = 35-29 = 6

Finally, F = D+E = 17+6 = 23

-------------

Summary:

A = 48

B = 29

C = 77

D = 17

E = 6

F = 23

G = 65

H = 35

I = 100

The table is attached to show how it looks when you replace all the letters with their proper values.

================================================

Part B

Focus on E = 6 which represents 6 people who do not like either sport. This is out of 100 total people. So 6/100 = 0.06 = 6% is the percentage who dislike either sport.

6%

================================================

Part C

H = 35 people do not like baseball

F = 23 people do not like football

There is a greater dislike for baseball.

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
