Vertical asymptotes can be found by setting the denominator equal to 0

x^2-6x = 0
factor out x
x(x-6)
set the two parts equal to 0
x = 0

x-6 = 0
x = 6

so the two x values are 0 and 6

ANSWER: B. x = 0, x = 6

Yasmine is having a birthday party. Five people are sharing 34's of a pizza. What portion of the whole pizza will each person re

Nady [450]

Answer:

3/20

Step-by-step explanation:

Given that :

Share for 5 persons = 3/4 of a whole pizza

Each person gets an equal size of the share :

Hence, share per person :

Portion of pizza / number of persons

3/4 ÷ 5

3/4 * 1/5

= (3*1) / (4*5)

= 3/20

Imagine an experiment in which one student is selected at random from among all currently enrolled students in this university.

Alex_Xolod [135]

Answer:

$\left \{ x\varepsilon U;x\notin A \right \}$ , $\left \{ x\varepsilon U;x \varepsilon A\cap B \right \}$ , $\left \{ x\varepsilon U;x \notin A, x \varepsilon B \right \}$ , $\left \{ x\varepsilon U;x \notin A, x \notin B \right \}$ , $\left \{ x\varepsilon U;x \varepsilon A \cup B \right \}$ , $\left \{ x\varepsilon U;x \varepsilon (B-A)\cup (A-B) \right \}$

Step-by-step explanation:

Set refers to the well defined collection of objects.

We can express a set in set-builder form or in roaster form.

Roster form is a mathematical representation of a set that lists all of the elements of the set within the curly bracket, separated by commas.

A set-builder notation is a mathematical representation for describing a set that lists all of the elements of the set by stating the properties that its elements must satisfy.

Let A be the event that the selected student is classified as enrolled in engineering (one of the engineering schools), and let B be the event that the same student is currently enrolled in this class.

Let U denotes the set of all students currently enrolled in the university.

1. $\left \{ x\varepsilon U;x\notin A \right \}$

2. $\left \{ x\varepsilon U;x \varepsilon A\cap B \right \}$

3. $\left \{ x\varepsilon U;x \notin A, x \varepsilon B \right \}$

4. $\left \{ x\varepsilon U;x \notin A, x \notin B \right \}$

5. $\left \{ x\varepsilon U;x \varepsilon A \cup B \right \}$

6. $\left \{ x\varepsilon U;x \varepsilon (B-A)\cup (A-B) \right \}$

Gwar [14]

Answer:

0.0139

Step-by-step explanation:

Given that in a test for extrasensory perception, the experimenter looks at cards containing either a star, circle, wave, or square. (The subject cannot see the cards.)

Probability for guessing a correct shape out of 4 shapes = 0.25

Each trial is independent of the other

Hence X no of correct guesses is binomial with n = number of cards = 20 and p = constant probability =0.25

the probability a subject correctly guesses at least 10 of the 20 shapes

= $P(X\geq 10)\\= 1-F(9)$ , where F represents the cumulative probability upto 9

= 0.0139
