On a unit circle, 120 is in the second quadrant. the terminal line form a 60 degree angle with the negative part of the x axis, the x value is -1/2, and the y value is √3/2
tan120=(√3/2)/(-1/2)=-√3

3x - y = 2<br>and<br>2x + y = 4​
Naddik [55]

\frac{3}{1}Answer:

Step-by-step explanation:

3x-y = 2

2x+y =4

put them into slope intercept form

y=3x-2

y=-2x+4

Now, you can either graph it or use substitution

3x-2 = -2x+4

+2x +2x

5x -2 = 4

+2 +2

5x = 6

5x/5 = 6/5

x = 6/5

3x -2 = y

3(6/5) -2 = y

3 x 6 / 1 x 5 = 18/5

3 3/5 -2 = 1 3/5

Let me know if it's wrong.

Hope this helps

What conditions must hold for a probability distribution to be acceptable?
VashaNatasha [74]

A distribution of probabilities is a numerical means of describing all unique combinations and the probabilities for a provided random variable, and the further discussion can be defined as follows:

  • The distributions mean (average), basic difference, skewness, as well as courtesies, are among such factors.
  • A formula, table, or chart can show a probability distribution for discrete probability distribution X that providing \bold{p(x) = P(X=x)} for all x.
  • For just a discrete random variable, the probability assigns annual probabilities with only a countless multitude of unique x values.
  • <em><u>Each result is likely to be between 0 and 1, including.</u></em>

Therefore, the final choice is "Option A".

What is the probability that a point chosen at random in the given figure will be inside the smaller square?
Aliun [14]
I have to interpret that:

1) the smaller square has side length = 3 cm

2) the bigger square has side length = 5 cm

3) the smaller square is completely inside the bigger square.

4) the points cannot be outside the bigger square



Under those assumptions the probability that a point is inside the smaller square  is

P (inside the smaller square) = area of the smaller square / area of the bigger square

P (inside the smaller squere) = (3cm)^2 / (5cm)^2 =  9 / 25


Answer: 9 / 25
