Suppose the radius of circle a is equal to the diameter of circle

o-na [289]

We've all seen circles before. They have this perfectly round shape, which makes them perfect for hoola-hooping!Every circle has a center, which is a point that lies exactly at the... well... center of the circle. A circle is a shape where distance from the center to the edge of the circle is always the same:

ten selected students took a. altitude test out of the total score of 100 these students scored 60,50,50,70,40,80,65,55,50 and 9

<u>Answer:</u>

• mean = 61

• mode = 50

• median = 57.5

<u>Step-by-step explanation:</u>

• The mean is calculated by adding all the values together, and dividing the result by the number of values.

∴ mean = $\frac{60 + 50 + 50 + 70 + 40 + 80 + 65 + 55 + 50 + 90}{10}$

⇒ mean = $\frac{610}{10}$

⇒ mean = 61

• The mode of a set of values is the value that is the most common (has highest frequency) among them.

50 is the most common value.

∴ mode = 50

• The median is the middle-value of a set of ordered values.

∴ We have to first rearrange the set:

⇒ 40, 50, 50, 50, 55, 60, 65, 70, 80, 90

Now we need to find the middlemost value:

Since we have 10 values, which is an even number, we have to use the formula:

median = $\frac{(n/2)^{th} \space\ term \space\ + \space\ [(n/2) + 1]^{th} \space\ term }{2}$

where n is the number of values.

∴ median = $\frac{(10/2)^{th} \space\ term \space\ + \space\ [(10/2) + 1]^{th} \space\ term }{2}$

⇒ median = $\frac{5^{th} \space\ term \space\ + \space\ 6^{th} \space\ term }{2}$

The 5th and 6th terms in our ordered series are 55 and 60 respectively.

∴ median = $\frac{55 + 60}{2}$

⇒ median = 57.5

(ASAP!!) Given that point M is the midpoint of TS and UR which of the following triangle congruence methods could be used to pro

Natalka [10]

Answer: SAS or Side-Angle-Side

Step-by-step explanation: Two triangles are congruent if they have the same exactly 3 sides and same exactly 3 angles.

There are methods to help prove congruence.

For example:

<u>ASA</u> or <u>Angle-Side-Angle</u>: when two angles and the included side of one triangle are congruent to the corresponding parts of the other triangle;
<u>SAS</u> or <u>Side-Angle-Side</u>: when two sides and the included angle of one triangle is congruent to the corresponding parts of the other triangle;
<u>SSS</u> or <u>Side-Side-Side</u>: if three sides of one triangel are congruent to the three sides of the other triangle, they are congruent;

The triangles TUM and SRM are congruent because:

Lines RU and TS intersect at point M forming two pair of opposite angles, which are vertical and therefore, the same.

Being midpoint, point M divides RU into two equal segments: UM = MR. The same happens to TS: TM = MS.

Two sides and the included angle of one triangle is congruent to the corresponding parts of the other triangle, which means ΔTUM and ΔSRM are congruent and proved by SAS method.
