For the division part:

But I think your question differs than this..
Am I right?
as your options do not include 1
(−2)³ = (-2)(-2)(-2)
Note that:
two negative numbers multiplied together results in a positive
one negative and one positive number multiplied results in a negative
Multiply:
(-2)(-2) = 4
4(-2) = -8
-8 is your answer
hope this helps
The expression is 5-3L or five minus three L
240 homes in the county are between $175,000 and $225,000.
The image attached is associated with this question and m in it refers to the mean value which is $225000 here and d refers to the standard deviation which is $25000 here.
Now since m= $225000
and $175000= $225000-$50000= $225000-(2* $25000)= m-2d
Thus, as per the image area covered between m and m-2d= $225000
and $175000 is (34%+14%)of 500 homes= 68% of 500= 240 homes, is the answer.
A random variable X is said to follow a normal distribution if its parameters are mean and standard deviation. Every other distribution can be reduced to a normal distribution.
