In 2006, 75.9 percent of first-year college students responding to a national survey said that they used the Internet frequently for research or homework. A state university finds that 168 of an SRS of 200 of its first-year students said that they used the Internet frequently for research or homework. You wonder if the proportion of first-year students at this university who said that they used the Internet frequently for research or homework differs from the national value, 75.9 percent. Consider p as the proportion of first year college students at this university who use the Internet frequently for research or homework. The hypotheses that you will test are: H0: p = 0.759, Ha: p â 0.759

If the null hypothesis is true, the proportion who use the Internet frequently for research or homework from an SRS of 200 students would have (approximately) a Normal distribution with mean 0.759 and standard deviation . (Give your answer to four decimal places.)

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

they disappear if your absent from to long. i found out that the hard way.

step-by-step explanation:

brainliest lol i just need one more brainliest.

just get this app called photo math it should be able to do those
