First Option

$sin(A)=\frac{35}{37}$ , $cos(A)=\frac{12}{37}$

Step-by-step explanation:

We know that the sine function is defined as:

$sin(\alpha)=\frac{Opposite}{Hypotenuse}$

In the same way the cosine function is defined as:

$cos(\alpha)=\frac{adjacent}{Hypotenuse}$

Therefore it is fulfilled that:

Opposite: is the length of the side opposite angle

Adjacent: It is the length of the side that contains the angle of 90 ° and angle A

Hypotenuse: It is the length of the side opposite the angle of 90 °

So:

$sin(A)=\frac{35}{37}$

$cos(A)=\frac{12}{37}$

white males

29–30 . . . . . . . . . . . . 0.001372

jacob, non hispanic white male. 30 years old.

probability that jacob lives to be 30 years old.

since the given probabilities are probabilities of dying, i think we simply subtract it from 1 to get the probability of living. we will use the probability of non hispanic white male.

probability of living to be 30 y.o.

29 - 30 : 1 - 0.001477 = 0.998523

30 - 31 : 1 - 0.001503 = 0.998497
