Mathematics

LenaWriter [7]3 years ago

When numbers are written together like that, (other examples: 1/2(2), 4(8), 12(0.5)) It indicates multiplication.

When a negative number is multiplied by a positive number, the result will be negative.

-42 * 3.6 = -151.2

Answer: -151.2

Reasoning: the equation is -42•3.6= ? Even though it’s a negative, you multiply regularly so you can just use the absolute value for when you multiply but when you get your answer, don’t forget to see if you put a negative or if it’s positive- 42
x 3.6
so, when you multiply you get 1512. BUT there’s a decimal. And since there’s only one other number after the decimal, you put the decimal in the answer one space over [in between the 1 & 2] so the answer would be 151.2 but since there are two different signs, and when you have two different signs, you make it negative. So in the end it’s - 151.2 :)

Are sin and cos reciprocals of each other
sleet_krkn [62]
Hello,

When you compose 2 reciprocals functions, you will find 1.

ex f(x)=√x and g(x)=x² , x>=0
so that g(f(x))=(√x)²=x

sin(cos(0))=sin(1)=0,84147... rad and not 1.
Reciprocal function of sin (x) is arcsin(x).
Reciprocal function of cos (x) is arccos(x).

What is the equation of the following line written in general form? (The y-intercept is 7.)
White raven [17]
Well I believe the correct equation would be 3x-y+7 because the y- intercept is 7 which is positive. That could only mean that the answer with a positive 7 is correct.

hope this helps!!

Students in an introductory statistics course were asked the following questions as part of a class survey:(1) What is your gend
11Alexandr11 [23.1K]

Answers:

Gender = categorical, nominal variable

Sleep length = numerical, continuous

Bedtime = categorical, ordinal

Number of countries visited = numerical, discrete

Scale of dreading semester = categorical, ordinal

=========================

Explanation:

Gender is categorical because there are two categories or labels, male or female. It is nominal because we simply attach names to each label and we can't sort them or order them from highest to lowest. There is no ranking for gender.

Sleep length is numerical as it deals with numbers. I put continuous because someone could write 2.5 hours or 3.75 hours. If whole numbers are only allowed, then the variable would be discrete.

The bedtime portion is categorical as each time slot is a category. Like with the first part, they are simply labels. We can order them however from earliest to later on, which is why this variable is ordinal.

The number of countries visited is numeric as expected, and it's also discrete because we can't visit 0.1 of a country. By "visit", I mean step foot in any part of the country for any length of time. It does not mean you have to explore every square inch of the territory.

The last part is categorical and ordinal. The scale ranking is ordered for us from 1 to 5. Despite the fact we have numbers here, the data is not numerical as the numbers 1 through 5 represent labels of "very little" through "a lot".
