What are the domain and range of the absolute value parent function?

Mathematics
1 answer:
dimaraw [331]3 years ago
6 0

Answer:

Step-by-step explanation:

The graph of the absolute value function looks like a V that opens UP and has its vertex at the origin, (0, 0).  There are no restrictions on the input, x, so the domain is (-infinity, infinity).

On the other hand, this function has no values less than zero.  Its range is

[0, infinity).

John rolls a six-sided number cube twice. What is the probability of getting an even number and then an odd number?
lubasha [3.4K]

Answer:

Option 2 - \text{Probability}=\frac{1}{4}

Step-by-step explanation:

Given : John rolls a six-sided number cube twice.

To find : What is the probability of getting an even number and then an odd number?    

Solution :              

When rolls a six-sided number cube twice

(1,1)  (1,2) (1,3)  (1,4)  (1,5)  (1,6)  

(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)  

(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)  

(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)  

(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)  

(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)  

Now,  

\text{Probability}=\frac{\text{Favorable outcome}}{\text{Total number of outcome}}

Favorable outcome of getting an even number and then an odd number:

(2,1) (2,3) (2,5) (4,1) (4,3) (4,5) (6,1) (6,3) (6,5)

So, Favorable outcome = 9

Total number of outcome = 36

\text{Probability}=\frac{9}{36}

\text{Probability}=\frac{1}{4}

Therefore, Option 2 is correct.

Two sections of a class took the same quiz. Section A had 15 students who had a mean score of 80, and Section B had 20 students
Ksju [112]

Answer:

86

Step-by-step explanation:

In this question, we are asked to calculate the average mean score for a group of students split into two different emerging groups.

We calculate the total score for each of the groups. This is done by multiplying the average score by the number of students.

Total score of section A is 15 * 80 = 1,200

For section B, total score is 20 * 90 = 1,800

Overall score is thus 1200 + 1800 = 3000

We add the scores together and divide by the total number of students in both sections

Average score is thus 3000/35 = 85.71 which is approximately 86

Jake drew an isosceles right triangle. What are the measures of the two acute angles? How do you know?
scoray [572]
SO you know that triangles add up to 180. A right angle equals 90 so 180-90=90. And an isosceles triangle means that 2 angles are congruent. SO 90/2 = 45. The measure of the 2 acute angles are 45
