Suppose that only 2 percent of all people are geniuses. If an IQ test indicates that Albert is a genius, but the test is only accurate 90 percent of the time, then the probability that Albert really is a genius is roughly:

P = 1,8 %

Step-by-step explanation:

From the whole population, only 2% are geniuses. But test results,              are accurate 90 %. So the probability that Albert really is a genius is:

P = 0,02 * 0,9

P  = 0,018      or    P = 1,8 %

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
