Point B has coordinate B(1, -1).
What is the coordinate of B' under a scale factor of 3?
(1,-1)
(3, 3)
(-2,2)
4-6, 6)

1) is right

step-by-step explanation:

answer: sine

step-by-step explanation:

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.

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 %
