This Venn diagram shows the pizza topping preferences for 9 students. Let event A = The student likes pepperoni. Let event B = T

Lelechka [254]

Answer:

$P(A\ or\ B)=\frac{7}{9}$

Step-by-step explanation:

We need to use the formula to calculate the probability of (A or B) where

A=Probability a student likes pepperoni

B=Probability a student likes olive

A and B =Probability a student likes both toppings in a pizza

A or B =Probability a student likes pepperoni or olive (and maybe both), a non-exclusive or

The formula is

$P(A\ or\ B)=P(A)+P(B)-P(A\ and\ B)$

Since 6 students like pepperoni out of 9:

$P(A) = \frac{6}{9}$

Since 4 students like olive out of 9:

$P(B) = \frac{4}{9}$

Since 3 students like both toppings out of 9

$P(A\ and\ B) = \frac{3}{9}$

Then we have

$P(A\ or\ B)=\frac{6}{9}+\frac{4}{9}-\frac{3}{9}$

$P(A\ or\ B)=\frac{7}{9}$

5) The graph of the parent linear function f(x) = x is shown in black on the coordinate grid. Write the function that represents

djyliett [7]

Answer:

(m) increased, (b) unchanged. g(x)

(m) decreased, (b) unchanged. m(x)

(m) unchanged, (b) increased. h(x)

(m) unchanged, (b) decreased. n(x)

f(x): m = -1/2 b = 2

g(x): m = 1/3 b = -3

h(x): m = 2 b = 0

1 Select all relations that are functions from the choices below

Daniel [21]

Answer:

Option (D).

Step-by-step explanation:

If the graph of a relation has two output values for a single input value, relation will not be considered to be a function.

Option (A).

For the input values of x = -1, there are two output values, y = -1, 1.

Therefore, given relation is not a function.

Option (B).

Since, all the parabolas don't represent a function, given parabola in the graph is not a function.

Option (C).

Not a function. It's a relation.

Option (D).

Line plotted in the graph has a distinct output value for every input value.

Therefore, the given graph represents a linear function.

The graph attaches shows the function f(x) and the table represents the function g(x)

Fed [463]

Answer:

Statement D is true

Step-by-step explanation:

We should know the following:

x-intercept is the value of x when y = 0

y-intercept is the value of y when x = 0

As shown on the graph, we can deduce the following:

For f(x) : at y = 0 ⇒ x = 1 And at x = 0 ⇒ y = -1

So, for f(x) ⇒ x-intercept = 1 & y-intercept = -1 

For g(x) : at g(x) = 0 ⇒ x = -1 And at x = 0 ⇒ g(x) = 1

So, for g(x) ⇒ x-intercept = -1 & y-intercept = 1

Comparing the results with the given options:

A) the x-intercept of f(x) is equal to the x-intercept of g(x) (Wrong)

B) the y-intercept of f(x) is equal to the y-intercept of g(x) (Wrong)

C) the y-intercept of f(x) Is greater than the y-intercept of g(x) (Wrong)

D) the x-intercept of f(x) is greater than the x-intercept of g(x) (true)
