S_A_V [24]3 years ago
6 0

For this case we have that by definition of trigonometric relations that the sine of an angle is equal to the opposite leg to the angle on the hypotenuse. That is to say:

Sin (43) = \frac {a} {26}

Clearing the value of "a":

a = 26 * sin (43)\\a = 26 * 0.68199836\\a = 17.73195736

Rounding off we have:

17.7

Answer:

Option B

Find the probability of exactly three successes in six trials of a binomial experiment in which the the probability of is 50%.
Lyrx [107]

Start by doing the binomial expansion of (x+y)^6 where x represents success. This is

(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)

We are interested in the x^3y^3 term which represents exactly 3 sucesses. Since the probalbility of sucess and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is

20/64 = .3125 which is 31.25%
