Answer:
102
Step-by-step explanation:
triangle area = 180 degrees
straight line = 180 degrees
180 - 127 = 53
49
49 + 53 + 3rd angle = 180
3rd angle = 78
180-78 = x
x = 102
Answer:
There is a 95% probability that the portfolio would not loose more than 30% of its value.
Step-by-step explanation:
The confidence interval for proportions (<em>p</em>) is:

The information provided is:

For 95% confidence level the critical value of <em>z</em> is:

The 95% confidence interval for average annual return is:

The lower limit of the 95% confidence interval is -28%.
This implies that the portfolio would not loose more than 28% of its value.
Thus, there is a 95% probability that the portfolio would not loose more than 30% of its value.

When y = 0,

When x = 0,

Therefore, Ordered pairs are (0,1), (3,0), etc.

Step-by-step explanation:
Answer:
4x + y = -1
Step-by-step explanation:
To get both variable terms on the same side, you can add 4x. Its coefficient will then be positive, and all coefficients are mutually prime, so you're done.
4x +y = 4x -4x -1 . . . 4x added to both sides
4x + y = -1 . . . . . . . simplify
