Answer:
z-score for value 560 = 0.6
z-score for value 650 = 1.5
z-score for value 500 = 0
z-score for value 450 = -0.5
z-score for value 300 = -2
Step-by-step explanation:
We are given a sample with a mean of 500 and a standard deviation of 100.
i.e., 
= 500 and 
= 100
The z score distribution is given by;
Z = 
~ N(0,1)
where X represents the data values;
- So, z score for value 560 is;
z score = 
= 0.6
- So, z score for value 650 is;
z score = 
= 1.5
- So, z score for value 500 is;
z score = 
= 0
- So, z score for value 450 is;
z score = 
= -0.5
- So, z score for value 300 is;
z score = 
= -2

Answer:
y = 25
Step-by-step explanation:
Given that,
m∠PTQ = 3y –10 and m∠QTR = y
We need to find the value of y so that ∠PTR is a right angle.
For a right angle, one of the angle is 90 degrees. The sum of the angle of a triangle is equal to 180 degrees. So,
3y –10 + y + 90 = 180
Taking like terms together
3y+y = 180 -90 +10
4y = 100
y = 25
So, the value of y is 25.

Answer: First Option: Robin's graph is a reflection of Giselle´s graph over the x-axis.
A reflection of the graph f(x)=y is g(x)=-y. In this case y=x^2, then:
g(x)=-x^2 that corresponds with the Robin's function
