Step-by-step explanation:
30+30 is 60
60+35 is 95
Another way to do this is to use multiplication then add. (30x2=60)
Hope I helped!
S and P are mutually exclusive events.
P ( S ) = 20% = 0.20
P ( T ) = 22 % = 0.22
The probability of mutually exclusive events:
P ( S or T ) = P ( S ) + P ( T )
P ( S or T ) = 0.20 +0.22 = 0.42
Answer: The probability of ( S or T ) is 0.42 or 42 %.
Times both sides by -1
-8x=x²-20
add 8x both sides
0=x²+8x-20
factor
what 2 numbers multiply to get -20 and add to get 8
-2 and 10
0=(x-2)(x+10)
set to zero
x-2=0
x=2
x+10=0
x=-10
x intercepts at x=-10 and 2 or at the points
(-10,0) and (2,0)
