Answer:
Step-by-step explanation:
probability ∈[0,1]
or probability ≥0
and ≤1
so a,b,g cannot be the probability of an event.
Use PEMDAS
20 * 20/5 + 100 - 50
Multiply and divide first
20 * 20 = 400
400/5 = 80
Add 100 and then subtract 50
80 + 100 = 180
180 - 50 = 130
130 is the answer.
Step-by-step explanation:
x^2 + 13x + 36 = (x+4)(x+9)
x = -4 or x = -9
A=pi • r^2 , 3.2^2= 10.24 , 10.24 • 3.14= 32.1536 and then ur answer when you simplify is 32
