Answer:
I = 
Step-by-step explanation:
Given
E = 9RI ( isolate I by dividing both sides by 9R )
= I
Answer:
x = 3y + 1
Step-by-step explanation:
You need to find the relationship between x and y before finding the y-intercept.
0-(-1) = 1
1-0 = 1
2-1 = 1
1-(-2) = 3
4-1 = 3
7-4 = 3
As x increases by 1, y increases by 3.
At x = 0, y is already 1. Thus:
x = 3y + 1
Okay first, use the sin rule (

so

sin^-1 this and you get 47.928....this is angle ADB
and as it is on a straight line, 180 - this angle gets ADC
180 - 47.928.... = 132.07
There's a 2/15 chance I think. 2 toppings out of 15, so 2/15. This is approximately 13% chance.
