Find the Greatest Common Factor (GCF)
GCF = 5ab
Factor out the GCF (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
5ab(15a^b/5ab + -10ab^2/5ab)
Simplify each term in parentheses
<u>5ab(3a - 2b)</u>
Answer:
The pink one
Step-by-step explanation:
3^-5 x 3^2 = 3^(-5+2) = 3^-3
The value of p(a) is 0.5
Mutually exclusive events are those events that do not occur at the same time
Given,
The a and b are mutually exclusive events
P(a AND b)=0
P(a)=0.48
p(a or b)=0.98
We know that,
P(a or b)=P(a)+P(b)-P(a AND b)
P(a or b)=P(a)+P(b)-0
P(a or b)=P(a)+P(b)
P(a)=P(a or b)-P(b)
Substitute the given values
P(a)= 0.98-0.48
P(a)=0.5
Hence, the value of P(a) is 0.5

Answer:
-2 sqrt (2) /3
Step-by-step explanation:
sin = -1/3 its in the 3rd quadrant so sin is negative cos is negative
sin^2 O + cos ^2 O = 1
1 - (1/9) = cos^2 O
