F(x)=2x^2+x-4

Find f(−10)

186

Step-by-step explanation:

f(x)=2x^2+x-4

f(-10)=2(-10)(-10)+(-10)-4=2(100)-10-4=200-10-4=190-4=186

Did a quiz on it

you probably already have the answer but anyways it's b. 15.0

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 %
