Reyna runs a textile company that manufactures t-shirts. the profit, p, made by the company is modeled by the function p=s^2+9s-142 where is the number of t-shirts sold. how many t-shirts should be sold to earn a profit of more than $2,000?

  Number of t shirts to be sold to have a profit of $2,000 = 42

Step-by-step explanation:

We have profit

We need to find how many T-shirts should be sold to earn a profit of more than $2,000, that is

  Number of t shirts to be sold to have a profit of $2,000 = 42

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 %
