7. A hotelier conducted a survey of guests staying at her hotel. The table shows some of the results of her survey.
Type of gues
Probability
Man
0.7
Woman
0.3
American man
0.2
American woman
0.05
Vegetarian
0.3
Married
0.6
a. A guest was chosen at random. From the table work out these probabilities:
i The guest was American
The guest was unmarried
The guest was not a vegetarian
b. Explain why it is not possible to work out from the table the probability of a
guest being a married vegetarian
c. From the table, give two examples of pairs of types of guest that would form a
pair of mutually exclusive events.
d. From the table, give one example of a pair of types of guest that would form a
pair of exhaustive events.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

no oblique asymptote

step-by-step explanation:

to find the oblique asymptote of f(x)

here numerator has degree 1 and denomintor degree 2

degree of numerator < degree of denominator

hence there is no oblique asymptote

when the degree of the denominator > that of the numerator, we saw that the value in the denominator got so much bigger, so quickly,   giving us a horizontal asymptote of the x-axis. or we can write

f(x) = a polynomial of x + a proper fraction.

in this case only we have oblique asymptotes but not when numerator has less degree.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
