The events are independent because they are not affected by the other coin toss. Hope this helps^-^
The base angles of isosceles triangles are congruent therefore Angle c also measures 4x+6. add all 3 angles of any triangle you always get 180
3x+47 + 4x+6 + 4x+6=180
11x=121
x=11 the three angles measure 80, 50, and 50
Answer:
P(x) = -1.6x + 52
Step-by-step explanation:
Let 2000 as the start point, so it will be the year 0, x = 0, and the population that uses newspaper (y) will be y = 52%. The slope of a linear function is how much it increases or decreases, so the slope is -1.6 (the minus signal indicates that it's decreasing). The slope can also be calculated by the equation:
a = Δy/Δx, where a is the slope, and Δy and Δx are the difference between two points in the function.
So, for x years, the population percentage will be y:
-1.6 = (y - 52)/(x - 0)
-1.6x = y - 52
y = -1.6x + 52
P(x) = y
P(x) = -1.6x + 52
