Answer:
y = 1.6 x
y = 24
Step-by-step explanation:
The general equation of a direct variation is
y = k x
In this case
x = 10
y = 16
y = k*x
16 = 10*k
16/10 = k
k = 1.6
y = 1.6x
================
Let x = 15
y = 1.6 * 15
y = 24
Assuming a fair die,
probability of winning 0.25 = (2/6) = 1/3
probability of losing 0.25 = (4/6) = 2/3
Expected win
= sum (proba.*winning)
=0.25*(1/3) + (-0.25)(2/3)
=-0.25/3
= - (1/12) dollars (negative sign means expecting to lose)

Answer:
angle C = 78
angle D = 108
Step-by-step explanation:
the measure of angle A is 102
To find the measure of angle C
let Angle C be x
102 + x = 180 (linear pair)
x = 180 -102
x = 78
angle C = 78
angle B = 78 (vertically opposite angles are equal)
angle D = 108 (vertically opposite angles are equal)
