A random sample of 10 subjects have weights with a standard deviation of 11.0995 kg. What is the variance of their weights?

goblinko [34]

Answer:

$123.19890025 kg^2$

Step-by-step explanation:

We are given that

Standard deviation, s=11.0995 kg

Sample size, n=10

We have to find the variance of their weights.

We know that

Variance= $(standard\;deviation)^2$

Using the formula

The variance of their weights

= $(11.0995)^2$

= $123.19890025 kg^2$

Hence, the variance of their weights= $123.19890025 kg^2$

Help with a graph problem pleaseeeeee graph the line with slope -1/2 passing through the point (-1,2)

timofeeve [1]

When you know the slope $m$ and a point $(x_0,y_0)$ of a line, the equation of the line is given by

$y-y_0=m(x-x_0)$

So, your line is given by

$y-2=-\dfrac{1}{2}(x+1) \iff y=-\dfrac{1}{2}x-\dfrac{1}{2}+2=-\dfrac{1}{2}x+\dfrac{3}{2}$

Please help due today i beg of u .......A compute technician keeps track of his earning through tout each months. The technician

Mnenie [13.5K]

Answer:

$y=35x+200$

The slope is 35 and it means the technician earns $35 per hour.

Step-by-step explanation:

The technician finds that

when he works 55 hours during the month, he earns $2,125;
when he works 30 hours, he earns $1,250.

Let

x = number of hours worked

y = amount of money earned

Find the slope of the linear equation:

$\dfrac{2,125-1,250}{55-30}=\dfrac{875}{25}=35$

Equation of the linear function:

$y-1,250=35(x-30)\\ \\y=35x-1,050+1,250\\ \\y=35x+200$

The slope is 35 and it means the technician earns $35 per hour.
