We can show ABCD is a square by showing all the angles are right angles and congruency.
Draw two diameters that are perpendicular to each other. We can prove that they are similar by stating the intercepted arc's degree measure is twice that of the angle's. Thus, the arc is 180° and the angle intercepted is 90°. We can do this for every angle of the square. We can use Pythagorean theorem to show that the sides are equal. This can be done by setting a variable "2x" = to the side length of the square. To find x, we can use Pythagorean theorem on an isoceles triangle.

*Note: Remember 8 is the hypotenuse because 4 is the radius, 8 is the diameter.*

Now, we solve and get

Now we know x, 2x is just two times that. Every side can be expressed in that way. Now that we know it is a square, we can find the area by finding

step-by-step explanation:

i found the life tables for the year 2012.

life table of males at age 30. probability of dying between ages x and x+1

total population:

29–30 . . . . . . . . . . . . 0.001030

30–31 . . . . . . . . . . . . 0.001061

males:

29–30 . . . . . . . . . . . . 0.001420

30–31 . . . . . . . . . . . . 0.001448

white population

29–30 . . . . . . . . . . . . 0.001005

30–31 . . . . . . . . . . . . 0.001037

white males

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

30–31 . . . . . . . . . . . . 0.001399

non hispanic white population

29–30 . . . . . . . . . . . . 0.001083

30–31 . . . . . . . . . . . . 0.001116

non hispanic white males

29–30 . . . . . . . . . . . . 0.001477

30–31 . . . . . . . . . . . . 0.001503

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
