Seventy percent of light aircraft that disappear while in flight in a certain country are subsequentlydiscovered. of the aircraft that are discovered, 60% have an emergency locator, whereas 90% of theaircraft not discovered do not have an emergency locator. suppose that a light aircraft has disappeared. a) if it has an emergency locator, what is the probability that it will not be discovered? b) if it does not have an emergency locator, what is the probability that it will be discovered? c) if we consider 10 light aircraft that disappeared in flight with an emergency recorder, what isthe probability that 7 of them are discovered?

step-by-step explanation:

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

step-by-step explanation:

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
