In quadrant III, cosine is <u>negative</u>
In quadrant III, sine is <u>negative</u>
x^2+y^2 = 1 represents the unit circle. This is a circle centered at the origin with radius 1. The point (x,y) is on the unit circle where x = cos(theta) and y = sin(theta)
If theta is between 180 and 270 degrees, then
x = cos(theta) leads to -1 < x < 0, ie x is some negative number between -1 and 0
y = sin(theta) leads to -1 < y < 0, so y has similar properties to x above.
Because we don't know what value theta is exactly, we can only comment on the fact that each result is positive or negative.
The four quadrants are set up where quadrant 1 is in the upper right corner. Then you move counter-clockwise to sweep through the other quadrants 2 through 4.
so what you do is either 2 + 2 and then you do 5 * 8 and then you do 6 / 9 and then you get that number do you divide that by 2 and then you multiply 6 from the 8 if I got it wrong you don't hate on me
Answer:
i didn't understand what your question is
Answer:
Step-by-step explanation:
The given information is expressed as
Side effect no side effect total
Adult 7 43 50
Children 22 28 50
Total 29 71 100
Probability is expressed as
Number of favorable outcomes/number of total outcomes
For the probability that an adult has side effects,
Total number of outcomes = 50
Number of favorable outcomes = 7
Probability that an adult has side effects = 7/50 = 0.14
For the probability that a child has side effects,
Total number of outcomes = 50
Number of favorable outcomes = 22
Probability that an adult has side effects = 22/50 = 0.44
Therefore, it is more likely that a child has side effects compared to an adult
The information's given in the question are of vital importance. These information's should be very useful while getting to the desired answer of the given question.Let us now concentrate on the problem that needs to be solved.
The height of the sign that casts a shadow of 4 meters is = 5 meters
Then
The height of the tree that casts a shadow of 30 meters = (5/4) * 30 meters
= 150/4 meters
= 37.5 meters
So the tree casting a shadow of 30 meters is actually 37.5 meters in height. I hope the procedure is simple enough for you to understand.
