Answer:
The mean of the z scores will be 0, and the standard deviation of the z scores will be 1.
Step-by-step explanation:
When the data is converted to z-scores the mean and standard deviation no longer stay the same. Both these quantities are transformed into news values.
Values converted to z scores follow a standard Normal curve. This curve is symmetric about the mean. The mean of standard normal curve is 0 with a standard deviation of 1.
Therefore, the correct answer is:
The mean of the z scores will be 0, and the standard deviation of the z scores will be 1.

Dilation involves changing the size of a shape
The vertex of the image is (5,40)
<h3>How to determine the image</h3>
The vertex of the pre-image is given as:
(1,8)
The scale factor (k) is given as:
k = 5
So, the vertex of the image is:
Vertex = (1,8) * 5
This gives
Vertex = (5,40)
Hence, the vertex of the image is (5,40)

Answer:
x = 110
Step-by-step explanation:
all angles of the triangle MUST add up to 180 degrees.
45 + 65 = 110
180 - 110 = 70
since x is sittling on a 180 degree angle, the sum of 70 and x must equal 180 too
180 - 70 = 110
