<h3>Given:</h3>
<h3>To find:</h3>
The size of the unknown angle "x"
<h3>Solution:</h3>
The given polygon is a Pentagon so the sum of interior angle will be,

n means the number of sides
Let's substitute the values according to the formula.


Now, we can find the sum of one interior angle.

n means the number of sides.
Let's substitute the values according to the formula.

<span>A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 18 minutes. How large a sample should she take to estimate the mean time to within 4 minutes with 97% confidence?
-----
n = [z*s/E]^2
---
n = [2.17*18/4]^2 = 96 when rounded up

Remember that if lines are parallel, they will have the same slope. Also, the number added or subtracted in the equation is the y intercept, or the y value when the x=0. They gave you the point (0,-7) so really, they just gave you the y intercept. How nice!! That means you just use the same slope as the original and then add -7 to it to get your equation. With that knowledge, you can now easily identify the correct answer!!
Answer:
here is your answer
A matrix is a rectangular arrangement of numbers into rows and columns. Each number in a matrix is referred to as a matrix element or entry. The dimensions of a matrix give the number of rows and columns of the matrix in that order. Since matrix A has 2 rows and 3 columns, it is called a 2 × 3 2\times 3 2×3 matrix.
A) because it is 2/3 past 1
