Which statements describe the graph of 2 8/9 ≥ x on a number line? Select three options.

andrezito [222]

Answer:

✔️The graph contains point zero

✔️There's a closed circle on 2⁸/9

✔️The arrow points to the left

Step-by-step explanation:

The inequality, 2⁸/9 ≥ x, implies that 2⁸/9 is either equal to x or more than x. In other words, the highest value of x is 2⁸/9. Possible value of x is equal to or less than 2⁸/9.

This, on a number line, we would graph the information as follows:

✔️The graph contains point zero

Rationale: point zero is less than 2⁸/9

✔️There's a closed circle on 2⁸/9

Rationale: this indicates 2⁸/9 is included in the possible value of x

✔️The arrow points to the left

Rationale: possible value of x ranges from 2⁸/9 and below.

**please help brainliest best answer* Suppose the total market potential for MP3 players in Middletown is estimated at $150,000

Mila [183]

<h3>Answer:</h3>

$34,500

23% of $150,000 = 0.23×$150,000 = $34,500

_____

<em>Comment on percentages</em>

The % symbol is a shorthand way to write /100. Thus 23% = 23/100 = 0.23. (Both the fraction and the decimal are pronounced "twenty-three hundredths.")

Would the quotient be the same if you multiply by numerator and the denominator by 100? Explain

tamaranim1 [39]

Answer:

Yes, the quotient will be the same

Step-by-step explanation:

we know that

If the numerator and denominator of a fraction be both multiplied by the same number, the quotient will not be altered

Because is the same that you multiply the fraction by 1, and remember that when you multiply by 1, you always get your original number

$\frac{a}{b}(\frac{100}{100})=\frac{a}{b}(1)=\frac{a}{b}$

therefore

Yes, the quotient will be the same

Prove that sequence an = (3^n)/(2n)! is monotone

krek1111 [17]

When $n=1$ , you have $a_1=\dfrac3{2!}=\dfrac32$ .

When $n=2$ , you have $a_2=\dfrac{3^2}{4!}=\dfrac38$ .

Clearly, $a_1>a_2$ .

Assume $a_k$ . Now when $n=k+1$ , you have

$a_{k+1}=\dfrac{3^{k+1}}{(2k+2)!}=\dfrac3{(2k+2)(2k+1)}\times\dfrac{3^k}{(2k)!}=\dfrac3{(2k+2)(2k+1)}a_k$

Therefore by induction the sequence is monotone (decreasing).
