Answer:
a = 
and b = 
Step-by-step explanation:
As we know, the radius of the unit circle is 1 unit (it is the hypotenuse in the right triangle, the blue line)
We use trigonometric formulas to find out a and b
- Sin(45) = opposite side / hypotenuse
<=> Sin(45) = b / 1
<=> b= Sin(45)*1 =
- Cos(45) = adjacent side / hypotenuse
<=> Cos(45) = a / 1
<=> a = Cos(45)*1 =
So: a = and b =
Answer:
A. The data are continuous because the data can take on any value in an interval.
Step-by-step explanation:
The data surveyed is the exact mass, in grams, of food eaten by each person each day.
This type of data is continous, not discrete. The mass can take any value within the domain of positive real numbers. It represents a physic variable, and they are always continous.
If you would like to know how many papers will be missing the name, you can calculate this using the following steps:
30% of 200 homework papers = 30% * 200 = 30/100 * 200 = 60 homework papers
The correct result would be a) between 50 and 70 papers will be missing the name.
Blue: = because the equal sign is stating that it’s the same.
B
Two points is a line
One capital letter is the plane
