Orange box:
The incorrect statement is B. The theoretical probability is the probability of an event occurring that is expected. In this case, the theoretical probability of selecting a dime is 4/25.
Purple box:
The incorrect statement is C. The difference between the theoretical and experimental probability is not 1/10. The difference between the experimental and theoretical probability is 0.015 or 3/200.
6/25 = 0.24
9/40 = 0.225
0.24 - 0.225 = 0.015
Hope this helps!! :)

Answer: Choice B</h3>
The set notation includes all values from -5 to 0, but the domain only includes the integer values
eg: something like -1.2 is in the second set, but it is not in the set {-5,-4,-3,-2,-1}
==========================================================
Further explanation:
Let's go through the answer choices one by one
- A. This is false because 0 does not come before -5, but instead -5 is listed first. The order -5,-4,-3,-2,-1,0 is correct meaning that
is the correct order as well. - B. This is true. A value like x = -1.2 is in the set
since -1.2 is between -5 and 0; but -1.2 is not in the set {-5, -4, -3, -2, -1, 0}. So the distinction is that we're either considering integers only or all real numbers in this interval. To ensure that we only look at integers, the student would have to write 
. The portion 
means "x is in the set of integers". The Z refers to the German word Zahlen, which translates to "numbers". - C. This is false. The student used the correct inequality signs to indicate x is -5 or larger and also 0 or smaller; basically x is between -5 and 0 inclusive of both endpoints. The "or equal to" portions indicate we are keeping the endpoints and not excluding them.
- D. This is false. Writing
would not make any sense. This is because that compound inequality breaks down into 
. Try to think of a number that is both smaller than -5 AND also larger than 0. It can't be done. No such number exists.
Answer:
z= 104
y=76
x=76
Step-by-step explanation:
z+76= 180. solve for z
z=x
y=76
