We have an inscribed angle here. Angle YXZ is an inscribed angle.

Angle YXZ can also be expressed as simply angle x but I will use angle YXZ.

Angle YXZ = (1/2)(arc YZ)

Angle YXZ = (1/2)(144°)

Angle YXZ = 72°

Done!

Answer for 7: C

Answer for 9: A

Step-by-step explanation for 7:

Because the variable is an exponent, we know there are no real numbers which cannot be placed in the exponent. Therefore, the domain is all real numbers.

Step-by-step explanation for 9:

Test a few values for x. Notice as the x value gets higher, the y value gets exponentially higher. Notice as the x value gets lower, the y value approaches 0, but no value of x will have y equal to or less than 0. Therefor, the asymptote, or line that cannot be crossed is 0 - making A the correct solution.

Answer:

The normal quantile plot is provided below.

Step-by-step explanation:

The standardized normal scores are known as <em>z</em>-scores.

If there are <em>n</em> values in a data set then the area corresponding to these <em>n</em> values is given by:

\text{Area}=\frac{i-0.5}{n}

Here, <em>i</em> € {1, 2, ..., n}.

Arrange the data provided in ascending order.

S = { 31.8, 34.8, 38.2, 40.3, 44.2}

Consider the table for the <em>z</em>-scores.

To form the normal quantile plot, make a scatter plot with the <em>z</em>-scores on the <em>y</em>-axis and the values provided on the <em>x-</em>axis.

The normal quantile plot is provided below.
