Lana71 [14]

Answer:

C. The data are qualitative because they don't measure or count anything.

Step-by-step explanation:

Quantitative data is about numbers or counts. For example, the number of children of a couple is an example of quantitative data.

Qualitative data is about characteristics, when they don't count or measure anything. For example, if my favorite kind of movie is comedy, for example, it is an example of qualitative data. There are no counts or measurements.

So the correct answer is:

C. The data are qualitative because they don't measure or count anything.

<h2>Solving Quadratic Equations with the Quadratic Formula</h2>

<h3>Answer:</h3>

x = 3 and x = \frac{1}{2}\\

<h3>Step-by-step Explanation: </h3>

Recall:

if we have a quadratic equation, ax^2 +bx +c = 0, where a, b and c are real numbers and a \neq 0, x = \frac{-b \pm \sqrt{b^2 -4ac}}{2a}.

Given:

2x^2 -7x +3 = 0

Solving for x:

x = \frac{-(-7) \pm \sqrt{(-7)^2 -4(2)(3)}}{2(2)} \\ x = \frac{-(-7) \pm \sqrt{49 -4(2)(3)}}{2(2)} \\ x = \frac{7 \pm  \sqrt{49 -24}}{4} \\ x = \frac{7 \pm \sqrt{25}}{4} \\ x = \frac{7 \pm 5}{4}

Solving with the positive value:

x = \frac{7 +5}{4} \\ x = \frac{12}{4} \\ x = 3

Solving with the negative value:

x = \frac{7 -5}{4} \\ x = \frac{2}{4} \\ x = \frac{1}{2}

GEOMETRY HELP WILL MARK BRAINLIEST
klasskru [66]

Answer:

X = 2 / Z = 78

Explanation:

We are given 102 degrees, and the formula across from it, the one with the x, equals the same degrees. Knowing that we have to get them to equal each other, subtract 102-86, and you'll get 16. Next, divide 16 by the given number, 8, and you'll get x = 2

Knowing a straight line equals 180 degrees, subtract 180-102, and you'll get z, which is 78
