Step-by-step explanation: The middle quartile or <em>second quartile</em> as I like to call it is the median of the entire data set. Remember that the median is the middle number when the data is written from least to greatest.

<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

Leg <em>a</em> = 8

Leg <em>b</em> = 4

Hypotenuse <em>c</em> = <em>x</em>

<em />

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [Pythagorean Theorem]:                                            8² + 4² = x²
  2. Evaluate exponents:                                                                                         64 + 16 = x²
  3. Add:                                                                                                                   80 = x²
  4. [Equality Property] Square root both sides:                                                    √80 = x
  5. Rewrite:                                                                                                             x = √80
  6. Simplify:                                                                                                             x = 4√5

1 point<br> Solve: 0.75 (x + 200) = 150.5 (2 – 28)<br> type your answer...
adelina 88 [10]

Answer:

\huge \: x =  - 5417.33

Step-by-step explanation:

0.75 (x + 200) = 150.5 (2 – 28) \\

<u>Expand the terms and simplify</u>

That's

0.75x + 150 = 301 - 4214 \\ 0.75x + 150 =  - 3913

Subtract 150 from both sides of the equation

0.75x + 150 - 150 =  - 3913 - 150 \\ 0.75x =  - 4063

<u>Divide both sides by 0.75</u>

\frac{0.75x}{0.75}  =  -  \frac{4063}{0.75}  \\ x =  - 5417.333333

We have the final answer as

<h3>x = - 5417.33 </h3>
