The lengths (in inches) of a sample of snakes in the Clarmont Zoo's reptile house are as follows: 9, 15, 86, 13, 16, 101, 85, 10
elena-14-01-66 [18.8K]

Answer:

A higher value of standard deviation tells us that there is high variability in the length of the snake from the mean length of the snake.

Step-by-step explanation:

We are given the following information in the question:

Sample of snakes in the Clarmont Zoo's reptile house are as follows:

9, 15, 86, 13, 16, 101, 85, 10, 14, 16, 102

Formula:

\text{Standard Deviation} = \sqrt{\displaystyle\frac{\sum (x_i -\bar{x})^2}{n-1}}  

where x_i are data points, \bar{x} is the mean and n is the number of observations.

Mean = \displaystyle\frac{\text{Sum of all observations}}{\text{Total number of observation}}

Mean =\displaystyle\frac{467}{11} = 42.4545

Sum of squares of differences = 1119.206611 + 753.7520659 + 1896.206612 + 867.5702477 + 699.842975 + 3427.570248 + 1810.115703 + 1053.29752 + 809.6611568 + 699.842975 + 3545.661158 = 16682.72727

S.D = \sqrt{\frac{16682.72727}{10}} = 40.8445

Standard deviation:

  • Standard deviation tells you how spread out the data is.
  • It is a measure of how far each observed value is from the mean.
  • A low standard deviation indicates that the values tend to be close to the mean, while a high standard deviation indicates that the values are spread out over a wider range.

A higher value of standard deviation tells us that there is high variability in the length of the snake from the mean length of the snake. The data is overspread over a wide range.

Find the value of x and EF. A and B are midpoints.
Roman55 [17]

Answer:

x = 5.5

EF = 14

Step-by-step explanation:

We can use ratios to solve

AG                  7

----------- =  -----------------

EG                   2x+3

We know that EG is 2 times AG since A is the midpoint

AG                  7

----------- =  -----------------

2 AG                   2x+3

Canceling like terms

1                  7

----------- =  -----------------

2                    2x+3

Using cross products

1 (2x+3) = 2*7

2x+3 = 14

Subtract 3 from each side

2x+3-3 = 14-3

2x =11

Divide by 2

x = 11/2

x = 5.5

EF = 2x+3 = 2*5.5+3 = 14

What is the slope-intercept form of the equation of this line
makvit [3.9K]

\bf (\stackrel{x_1}{0}~,~\stackrel{y_1}{9})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{-2}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-2-9}{4-0}\implies \cfrac{-11}{4} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-9=-\cfrac{11}{4}(x-0) \\\\\\ y-9=-\cfrac{11}{4}x\implies y=-\cfrac{11}{4}x+9
