Do you think there is a number that you can squared that will get you -36?

Yes, it is -6.

Step-by-step explanation: When using a negative exponent, the negative number does not change so if you did -6 squared (-6 times -6) it would equal -36 instead of 36.

.

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 %
