Mathematics
1 answer:
Arisa [49]2 years ago
8 0

Answer:

-2/3

Step-by-step explanation:

Simplify each term.

Rewrite the division as a fraction.

3 n/ 9 n  −  1

Cancel the common factor of  3  and  9 .  

n/ 3 n  −  1

Cancel the common factor of  n .  

1 /3  −  1

To write  − 1  as a fraction with a common denominator, multiply by  3/3  

1 /3  −  1 x 3/3  

Combine  − 1  and  3/ 3 .

1/ 3  +  − 1 x3 /3

Combine the numerators over the common denominator.

1  −  1  x  3/3

Simplify the numerator.

− 2 /3

Answer:

24 Years

Step-by-step explanation:

Rule of 72 is an approximation that you can use to estimate the time it will take for something to double in value at a compound rate of interest

use the following equation

72/(i*100)

we have

72/(.03*100)

72/3=24

4 Find a formula for the exponential function passing through the points (-2, 4/9) and (3, 108)​
NemiM [27]

9514 1404 393

Answer:

  f(x) = 4·3^x

Step-by-step explanation:

We assume the function will be of the form ...

  f(x) = a·b^x

Substituting the given values, we can find 'a' and 'b'.

  4/9 = a·b^(-2)

  108 = a·b^3

Dividing the second equation by the first gives ...

  108/(4/9) = b^(3 -(-2))

  243 = b^5

  b = 3 . . . . . . 5th root

Using the second equation, we can find 'a':

  108 = a·3^3 = 27a

  a = 108/27 = 4

The formula for the exponential function is ...

  f(x) = 4·3^x

A couple wants to have three children. Assume that the probabilities of a newborn being male or being female are the same and th
liberstina [14]

Answer:

Let the G represent the Girl child

and, B represents the Boy child.

Then Sample Space = {BGG, GBG, GGB, BBG, BGB, GBB, BBB, GGG}

Thus, There are 8 sample space.

Then, Probability that couple have 1 boy = {BGG, GBG, GGB}

=  3 ÷ 8 = 0.375

Probability that couple have 2 boys = { BBG, BGB, GBB}

= 3 ÷ 8 = 0.375

Probability that couple have 3 boys = {GGG}

= 1 ÷ 8 = 0.125

Explain why the solution of 5x – 3 &gt; 14.5 or 5 x minus 3 greater than 14.5 or StartFraction 2 x plus 5 over 3 EndFraction les
slega [8]

Answer:

<u> There is no point where x = 3.5</u>

Step-by-step explanation:

Given the inequality

5x – 3 > 14.5

We are to find the range of all values of x

Add 3 to both sides of the equation;

5x - 3 + 3 > 14.5+ 3

5x > 17.5

x > 17.5/5

x > 3.5

Also for the inequality;

\frac{2x+5}{3}

Cross multiply;

2x+5 < 3(4)\\2x + 5 < 12\\

Subtract from both sides;

2x + 5-5 < 12-5\\2x < 7\\x

The solution to both inequalities are x > 3.5 and x < 3.5. <u>Since there is no point where x = 3.5</u>, hence the solution will have solution on all real numbers except at x = 3.5
