Mathematics
1 answer:
creativ13 [48]2 years ago
3 0

Answer:

A. True.

Step-by-step explanation:

I am assuming that it's

sec^2 x - 1 = tan^2 x

Now sec^2 x - 1  = 1 / cos^2 x - 1

= (1 - cos^2 x) / cos^2 x

But 1 - cos^2 x = sin^2 x

so sec^2 x - 1 = sin^2 x / cos ^2 x

= tan^2 x.

GenaCL600 [577]

Answer:

r = 0.

Step-by-step explanation:

The slope = (y2 - y1) / (x2 - x1)

So  (r - (-3)) / (-4-2) = -1/2

(r + 3) / -6 = -1/2

2(r + 3)  = 6

2r + 6 = 6

2r = 6 - 6 = 0

r = 0  (answer).

Explain the difference between qualitative and quantitative data. Choose the correct answer below. A. Quantitative data are coll
Leona [35]

The correct answer is F. Quantitative data are numerical in​ nature, while qualitative data are categorical in nature.

Explanation:

In research and all the different fields that apply to it, the word "data" refers to information, values or knowledge that can be used to understand a specific situation or phenomenon. Additionally, data can be of two different types quantitative and qualitative, these differ in their nature, the phenomenons they described and the way they should be analyzed. Indeed quantitative data refers mainly to numerical data or information about quantities such as statistics that are especially useful in mathematics, science and similar that focus on numbers. On the other hand, qualitative data refers to data based on categories or qualities and because of this qualitative data is used in humanistic research, although both types of data can be combined to study a phenomenon. Considering this, the key difference between both types of data is "Quantitative data are numerical in​ nature, while qualitative data are categorical in nature".
