I will help you out, but I'm not going to answer the question for you, because you should know these terms.

The mean in a set of data is the average. Add up all the numbers together and divide by how many ages there are total to find the mean.
Absolute deviation refers to the distance that the mean is from the other data points averaged together. Typing in absolute deviation on google will take you to glencoe, specifically a math page that explains in detail what absolute deviation means and consists of.

I can't see all the values to give a good example, but I hope now you know what you're doing.

Hope this helps!

A school, hospital, and a supermarket are located at the vertices of a right triangle formed by three highways. The school and h

Elan Coil [88]

Answer:

7.1 miles

Step-by-step explanation:

Consider right triangle HospitalSchoolSupermarket. In this triangle:

HospitalSchool = 14.7 mi;
HospitalSupermaket = 11.76 mi;
School Supermarket = 8.82 mi.

The shortest road from the main entrance of the supermarket to the highway that connects the school and hospital will be the height drawn from the point Supermarket to the hypotenuse HospitalSchool.

Let the length of this road be x mi and the distance from School to point A be y mi. Use twice the Pythagorean theorem for right triangles Supermarket SchoolA and SupermarketHospitalA:

$\left\{\begin{array}{l}x^2+y^2=8.82^2\\ \\x^2+(14.7-y)^2=11.76^2\end{array}\right.$

Subtract from the second equation the first one:

$x^2+(14.7-y)^2-x^2-y^2=11.76^2-8.82^2\\ \\14.7^2-2\cdot 14.7y+y^2-y^2=11.76^2-8.82^2\\ \\-29.4y=11.76^2-8.82^2-14.7^2\\ \\29.4y=155.5848\\ \\y\approx5.24\ mi$

Thus,

$x^2=8.82^2-5.24^2=50.3348\\ \\x\approx 7.1\ mi.$

A circle has a radius of 6 cm.

Lapatulllka [165]

Answer:

$1.5\pi$ cm

Step-by-step explanation:

A central angle measuring $45^\circ$ is $\frac{45^\circ}{360^\circ}=\frac{45}{360}$ , or $\frac{1}{8}$ of the entire circle. The circumference of the circle is given by the formula $2\pi r$ , which is $12\pi$ .
