Answer:
5% chance
Step-by-step explanation:
At first there is a one in 5 percent chance you get math. So thats a 20% chance. Now you have a 1 in 4 chance of getting history. Find a GCF (5) and combine you 5/20 chance and your 4/20 chance to get 5% chance!
y = 3/4x + 17/4
Step 1: Find slope <em>m</em>
m = (5 - 2)/(1 + 3)
m = 3/4
y = 3/4x + b
Step 2: Find <em>b</em>
5 = 3/4(1) + b
5 = 3/4 + b
b = 17/4
Step 3: Rewrite equation
39.273 ------> 39
- 8.58 ------> 9
----------------------
30.693 -----> 30
