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
Step-by-step explanation:
Since
varies directly as
we can write the relation as

where k is the constant of proportionality.
a) To solve for the k, we substitute the given values:


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

c) When y = 9,

Answer:
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.
27/25 is in the lowest form
Answer:
250
Step-by-step explanation:
52%-> 130
100%-> 250
