Step-by-step explanation:

$3 + \frac{9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{3 \times 4 + 9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{12 + 9}{4} = \frac{9}{x+4} \\ \\ \therefore \: \frac{21}{4} = \frac{9}{x+4} \\ \\ \therefore \:21(x + 4) = 36 \\ \\ \therefore \:21x + 84 = 36\\ \\ \therefore \:21x = 36 - 84\\ \\ \therefore \:21x = - 48\\ \\ \therefore \:x = \frac{-48}{21} \\ \\ \therefore \:x = \frac{-16}{7} \\ \\ \huge \red{ \boxed{ \therefore \:x = - 2 \frac{2}{7} }}\\ \\$

Answer: 17.89

Step-by-step explanation:

In binomial distribution, the standard deviation is given by :-

$\sigma=\sqrt{np(1-p)}$

As per given , we have

The number of vouchers in the sample with errors is denoted by x.

p= 0.20 , n = 2000

Then , $\sigma=\sqrt{2000\times(0.2)(1-0.2)}$

$\sigma=\sqrt{320}=17.88854382\approx17.89$

Hence, the standard deviation of x is 17.89.

4. Does the scatterplot have positive correlation, negative correlation, or no correlation?

bija089 [108]

Answer:

Negative Correlation

Step-by-step explanation:

Since the points are approximately lined up in a linear line pointing toward the bottom right, the slope of the best fit line would be a negative value. So the scatter plot shows a negative correlation.
