Answer:  The Z-value is a test statistic for Z-tests that measures the difference between an observed statistic and its hypothesized population parameter in units of the standard deviation. ...

Answer:

g(x) = (x + 1)^2 + 3

Step-by-step explanation:

When x is replaced by x - h, it results in a horizontal translation of h units.

When y is replaced by y - k, it results in a vertical translation of k units.

f(x) = x^2 is the original function.

Rewrite it as

y = x^2

To translate it 1 unit left, you need h = -1.

x - h = x - (-1) = x + 1. Replace x with x + 1.

Now you have y = (x + 1)^2.

To translate 3 units up, you have k = 3.

y - k = y - 3. Replace y with y - 3.

y - 3 = (x + 1)^2

Solve for y.

y = (x + 1)^2 + 3

Replace y with g(x).

g(x) = (x + 1)^2 + 3

What is a postulate?
zloy xaker [14]

Answer:

A statement, also known as an axiom, which is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived.

Step-by-step explanation:

The Addition Postulate: If you have one apple and Sally has one apple, when you both add the same quantity to your existing number of apples, you'll still have the same number of apples. Using algebra, the postulate states:

If x = y, then x + 4 = y + 4

The Subtraction Postulate: If you have ten apples and Sally has ten apples, when you both subtract the same quantity of apples from your existing number of apples, you'll still have the same number of apples.

If x = y, then x - 3 = y - 3

Without being repetitive, these same principles apply to both multiplication and division.

The Multiplication Postulate: If x = y, then x * 3 = y * 3

The Division Postulate: If x = y, then x / 7 = y / 7
