What we know:
Lot= 21 x 30ft
Perimeter=2l+2w
Want to put 4 corner post and one post every 3 ft
What we need to find:
How many post we need.
Perimeter=2 (21)+2 (30)=42+60=102ft
102/3=34
34 posts are needed.
Answer:201 students
Step-by-step explanation: Since there are seven kids riding in cars, you would subtract 7 from 1213 to get 1206 students. The six buses means you divide by 6 to get 201 students in each bus.

Answer:
Ask her why she is crying. If she explains why, listen and comfort her. If she says to "go away" or "i don't want to talk about it," give her space and come back later. She needs to let it out, so have patience :)
Hope this helps!!
Answer:
e) 0.14
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a driver does not have a valid driver's license.
B is the probability that a driver does not have insurance.
We have that:

In which a is the probability that a driver does not have a valid driver's license but has insurance and
is the probability that a driver does not have any of these things.
By the same logic, we have that:

We start finding these values from the intersection.
4% have neither
This means that 
6% of all drivers have no insurance
This means that
. So



12% of all drivers do not have a valid driver’s license
This means that 
So



The probability that a randomly selected driver either fails to have a valid license or fails to have insurance is about

So the correct answer is:
e) 0.14
