What is the range of y= x + 2?

Mathematics
1 answer:
Lelu [443]3 years ago
7 0

Answer:

A) all real numbers greater than or equal to 2

Domain: x\geq 0

Step-by-step explanation:

The variable in the radical <em>x </em>cannot be less than 0 as that wouldn’t be defined. So, the maximum that <em>x </em>can be is 0, and y=x+2. So, 0+2=2, and <em>y </em>is greater than or equal to 2.

Domain is x is greater than or equal to 0 because you cannot square a negative. So, it must not be less than 0. It could be 0 because square root of 0 is just 0.

Taya2010 [7]

Answer:

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  1- \frac{5}{9} = \frac{4}{9}

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given A high school club has 10 members who are seniors and 8 members who  are juniors

n(S) = 10 + 8 = 18

If a member is randomly selected to be the club president

Let 'E' be the event that the person will  be a senior

The probability that the person will  be a senior

      P(E) = \frac{n(E)}{n(S)}

     P(E) = \frac{n(E)}{n(S)} = \frac{10}{18} = \frac{5}{9}

The probability that the person will not  be a senior

P(E⁻) = 1 - P(E)

       =  1- \frac{5}{9} = \frac{4}{9}

Write 3.242424... as a mixed number.
victus00 [196]

Answer:

3\frac{8}{33}

Step-by-step explanation:

3.242424.....

This number can be written as 3  + 0.242424....

We convert the decimal part into fraction

Let x= 0.242424......

Multiply both sides by 100

100x = 24.2424....

     x=     0.2424.....

------------------------------------- (subtract  it)

99x = 24

Divide both sides by 99

So x= 24/ 99

simplify the fraction

\frac{24}{99} =\frac{8}{33}

3.242424... can be written as 3  + 0.242424....

Replace the fraction for decimal

So final answer is 3\frac{8}{33}
