Of the people at sunrise school, 40% are female students, 5% are staff, and the remaining people are male students. there are 270 more male students than female students. how many people are at sunrise school?

The total number of people is 1800

Step-by-step explanation:

If N is the total number of people in the school.

We know that 0.4*N = number of girls = Ng

0.05*N = staff = Ns

0.55*N = number of male students = Nm

We also know that

Ng + 270 = Nm

Now, we can wrie this as:

0.4*N + 270 = 0.55*N

And we solve it for N

270 = (0.55 - 0.4)*N = 0.15*N

N = 270/0.15 = 1800

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
