Write the quadratic equation y=x to the power of 2 -6x+7

  y = x^2 -6x +7

Step-by-step explanation:

You have already written it. All you need to do is use the appropriate symbol for "to the power of". That symbol is the caret (^).

  y = x^2 -6x +7

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 %
