Answer:

The sample size is n = 2

Step-by-step explanation:

From the question we are told that

   The margin of error is  E =4.266

    The standard deviation is  \sigma = 2.539

From the question we are told the confidence level is  99% , hence the level of significance is    

      \alpha = (100 - 99 ) \%

=>   \alpha = 0.01

Generally from the normal distribution table the critical value  of  \frac{\alpha }{2} is  

   Z_{\frac{\alpha }{2} } =  2.58

Generally the sample size is mathematically represented as  

   n = [\frac{Z_{\frac{\alpha }{2} } *  \sigma }{E} ] ^2

=>  n = [\frac{2.58  *  2.539  }{4.266} ] ^2

=>  n = 2

Can you answer this question?​
Debora [2.8K]

Answer: y= 3 times 2 to the power x. Second answer

Step-by-step explanation:

if you plug in 0 for x, y= 3x 1= 3

if you plug in 1 for x y= 3 x 2 = 6

Look at the x values and y values

(0,3) and (1, 6) on the graph. It matches answer number 2. Remember, 2 raised to the power 0 = 1 and 3 times 1 = 3. And 2 raised to the power 1 =2 and 3 times 2 = 6.

Answer:

x =   -  \frac{25}{3}

Step-by-step explanation:

\frac{10}{3}  =  \frac{x}{( -  \frac{5}{2}) }

<h3>i) simplify the complex fraction</h3>

\frac{10}{3}  =  -  \frac{2x}{5}

<h3>ii) simplify the equation using cross multiplication</h3>

5(10) =  - 2x(3)

50 =  - 6x

<h3>iii) swap the sides of the equation</h3>

- 6x = 50

<h3>iv) divide both sides of the equation by -6</h3>

\frac{ - 6x}{ - 6}  =  \frac{50}{ - 6}

x =  -  \frac{50}{6}

<h3>v) simplify the fraction</h3>

x =  -  \frac{25}{3}
