Answer:

P = 33z + 3

Step-by-step explanation:

To find the perimeter (P) sum the 4 sides

P = 8z - 3 + 10z - 3 + 6z - 1 + 9z + 10 ← collect like terms

= (8z + 10z + 6z + 9z ) + (- 3 - 3 - 1 + 10)

= 33z + 3

Answer:

$P=33z+3$

Step-by-step explanation:

The perimeter of a figure is given by the sum of the length of all sides.

So, for this figure, the perimeter is given by:

$P=(8z-3)+(10z-3)+(6z-1)+(9z+10)$

Adding the like terms, we have:

$P=(8z+10z+6z+9z)+(-3-3-1+10)\\$

which gives us the Answer.

$P=33z+3$

Find me equation of the circle with Center at ( 3, - 2) and radius of 3

blondinia [14]

The equation of a circle with center $(x_0,y_0)$ and radius $r$ is

$(x-x_0)^2+(y-y_0)^2=r^2$

In your case,

$x_0=3,\quad y_0=-2,\quad r=3$

Plug these values into the generic formula and you'll get your equation.

stat crunch A simple random sample of size n=250 individuals who are currently employed is asked if they work at home at least o

Masteriza [31]

Answer:

The 99% confidence interval for the population proportion of employed individuals who work at home at least once per week is between (0.104, 0.224).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 250, \pi = \frac{41}{250} = 0.164$

99% confidence level

So $\alpha = 0.01$ , z is the value of Z that has a pvalue of $1 - \frac{0.01}{2} = 0.995$ , so $Z = 2.575$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.164 - 2.575\sqrt{\frac{0.164*0.836}{250}} = 0.104$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.164 + 2.575\sqrt{\frac{0.164*0.836}{250}} = 0.224$

The 99% confidence interval for the population proportion of employed individuals who work at home at least once per week is between (0.104, 0.224).
