Explain how to find the deviation of an entry in a data set

1 answer:

3 0

The answer is: Find the mean of the differences with the other numbers in the set. Add the squared differences and then divide the total by the number of items in data in your set; take the square root of this mean of differences to find the standard deviation.

Pentagons add up to 540° so if you add all the degrees you get 400° and if subtracted from 540° you get 140°

George is given two circles, circle O and circle X 1 as shown. If he wants to prove that the two circles are similar, what would

salantis [7]

Answer:

Step-by-step explanation:

Given: The radius of circle O is r, and the radius of circle X is r'.

To prove: Circle O is similar to circle X.

Proof: Move the center of the smaller circle onto the center of the largest circle. Translate the circle X by the vector XA onto circle O. The circles now have the same center.

A dilation is needed to increase the size of circle X to coincide with the circle O. A value which when multiplied by r' will create r.

The scale factor x to increase X:

⇒

A translation followed by a dilation with scale factor will map one circle to the other, thus proving the given both circles similar.

Therefore, circle O is similar to circle X.

Suppose x represents an objects weight on Earth. Write two expressions: one that you can use to find the objects weight on Mars

tatyana61 [14]

The weight of an object is the product of its mass and the acceleration of gravity.
If g[e] is the acceleration of gravity on earth, and g[M] the same for Mars and g[m] the same for the moon,
then m[M]=m[e]g[M]/g[e] and m[m]=m[e]g[m]/g[e] where m[ ] denotes mass. Note that weight=mg (measured in newtons) while mass is in kilograms.
If g[M]=g[e]/3 and g[m]=g[e]/6 approximately. Then the weight of an object on Mars will be about a third of what it is on earth, while on the moon it would be about a sixth of what it is on earth.

Construct an inscribed circle in triangle PQR by finding the incenter of the triangle.

kotegsom [21]

Answer:

Step-by-step explanation:

To inscribe a circle in a given triangle PQR means to construct a circle in the triangle PQR. The incenter of a triangle is the midpoint in the triangle, which can be located by bisecting the three angles of the triangle individually.

The construction is shown in the attachment.
