Answer: -5

Step-by-step explanation: We can use a number line to help us visualize what's going on.

-2 tells us to move 2 units to the left us 0.

Then from there, -3 tells s to move an

additional 3 units to the left and we end up at -5.

I have shown the number line below.

So -2 + -3 is -5.

Suppose A and B are independent events if P(A) = 0.4 And P(B) = 0.1, what is P(A'uB)? APEX

Aloiza [94]

For Independent Events, P(A) × P(B) = P(A∩B)

so we have, P(A∩B) = 0.4×0.1 = 0.04

P(A') = 1 - 0.4 = 0.6

This information can be represented on a Venn diagram as shown below

P(A'∪B) means the union of everything that is not A with everything that is B

P(A'∪B) = 0.06 + 0.54 + 0.04 = 0.64

Answer:

1/2

Step-by-step explanation:

The rules of exponents are helpful.

(a^b)^c = a^(bc)

a^-b = 1/a^b

$25^{\frac{1}{2}}\times10^{-1}=\dfrac{(5^2)^{\frac{1}{2}}}{10^1}=\dfrac{5^{2\cdot\frac{1}{2}}}{10}\\\\=\dfrac{5^1}{10}=\dfrac{5}{10}=\boxed{\dfrac{1}{2}}$
