HELPP!!<br> Select the correct answer.<br> What is the value of arcsin ?
Schach [20]

For this case we have that by definition, it is called arcsine (arcsin) from a number to the angle that has that number as its sine.

We must find the arcsin (\frac {\sqrt {2}} {2}). Then, we look for the angle whose sine is \frac {\sqrt {2}} {2}.

We have to, by definition:

Sin (45) = \frac {\sqrt {2}} {2}

So, we have to:

arcsin (\frac {\sqrt {2}} {2}) = 45

solong [7]

Answer:

11/16 inch or 0.6875 inch

Step-by-step explanation:

26 * x = 17 7/8

17 7/8 = 143/8

143/8 ÷ 26 = 143/8 x 1/26 = 143/208 = 0.6875

0.6875 in = 11/16 in

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

Answer:

A. D

B. χ2 > 3.841

C. χ2 = 3.4806

D. 0.0621

Step-by-step explanation:

Question A: The hypotheses the dean should use are:

a) H0 : π1 - π2 ≥ 0 versus H1 : π1 - π2 < 0.

b) H0 : π1 - π2 ≤ 0 versus H1 : π1 - π2 > 0.

c) H0 : π1 - π2 ≠ 0 versus H1 : π1 - π2 = 0.

d) H0 : π1 - π2 = 0 versus H1 : π1 - π2 ≠ 0.

Answer: (d)

H0 : π1 - π2 = 0 versus H1 : π1 - π2 ≠ 0.

(B). Referring to the scenario above, the null hypothesis will be rejected if the test statistic is ________.

Answer: χ2 > 3.841

(C). Referring to the scenario above, the value of the test statistic is ________.

Answer: χ2 = 3.4806 (using the formula)

(D). Referring to the scenario above, the p-value of the test is ________.

Answer: 0.0621 (the answer could be looked up, in table)

Seriously, I don't like when they put "Not enough information". I feel like there is something missing.
Marizza181 [45]
Hey there Gary!

If Angle DBC is 73, you do subtract it from 180 to get ABD.

180 - 73 = 107

Angle ABD = 107
Angle DBC = 73

Angle ABD > DBC
or
Angle DBC < ABD

The line BD/DB is the same length in both angles, proving line AD is greater than CD. This is also justified by the fact that lines AB and CB are congruent.

I hope this helps, let me know if there's something wrong about my answer.
