Given: bd is a diameter m 1 = 100° m bc= 30° m dab 260 180 130

Step-by-step explanation:

1 and 2 share the same line (a line equals 180°) if 1 = 100° then 180°-100°=80°

2=80°

bc and 4 also share a straight line. if bc=30° then 180°-30°=150°

4=150°

this can be checked by adding them all together. a circle is equal to 360°.

100°+80°+30°+150°=360°

San makes up the straight line that makes up 1 and 2 (as you can see I have already answered the question a million times over) and as it is a straight line it is 180° which is backed up by all of the double checked math.

f(x) = y

f(-3) = -5

step-by-step explanation:

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
