7 0

Answer:

a> -32

Step-by-step explanation:

-40 < 2(a +12)

-40 < 2(a) +2(12) <em>(</em><em>expand</em><em>)</em>

-40 < 2a +24

-40 -24 < 2a <em>(</em><em>bring</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>)</em>

-64 < 2a <em>(</em><em>simplify</em><em>)</em>

2a > -64

a > -64 ÷2

a > -32

Suppose that E and F are two events and that Upper P left parenthesis Upper E and Upper F right parenthesisequals0.1 and Upper P
strojnjashka [21]

Answer:

P(F/E) = 0.5

Step-by-step explanation:

We have the following information:

P(E∩F)=0.1

P(E)=0.2

Additionally, the probability P(A/B) of event A given Event B is calculated as:

P(A/B) = P(A∩B)/P(B)

Now, we want the probability P(F/E), so it is calculated as:

P(F/E) = P(E∩F)/P(E)

Finally, replacing the values we get:

P(F/E) = 0.1 / 0.2

P(F/E) = 0.5
