G and H are mutually exclusive events. • P(G) = 0.5 • P(H) = 0.3 Find P(H OR G).

Sedaia [141]

Answer:

0.8

Step-by-step explanation:

Mutually exclusive:

P(G U H) = P(G) + P(H)

Because no intersection

P(G U H) = 0.5 + 0.3 = 0.8

I will mark brainly, help me with this question please.

Anna [14]

Step-by-step explanation:

Since $x$ varies directly as $\sqrt{y}$ we can write the relation as

$x = k\sqrt{y}$

where k is the constant of proportionality.

a) To solve for the k, we substitute the given values:

$5 = k\sqrt{13} = k(13)$

$\Rightarrow k = \dfrac{5}{13}$

b) The equation relation x and y can be written as

$x = \dfrac{5}{13}\sqrt{y}$

c) When y = 9,

$x = \dfrac{5}{13}\sqrt{9} = \dfrac{5}{13}(3) = \dfrac{15}{13}$

Amir says the graph of y= x2 + 16 has -4 as a zero. Is Amir correct? Explain.

sukhopar [10]

Answer:

Amir is wrong

Step-by-step explanation:

The function y = x² + 16 is positive for any value of x, hence the graph has no intersection with the x-axis and therefore has no real zero's.

If no zero's, -4 also can't be its zero.
