Someone help me, please
vredina [299]

Answer:

A) W'(-3,-2)  X'(-1,-5)  Y'(0,-4)

B) 2) Perpendicular angles

    4) Given

    5) AT = BT

    6) Statement : OT = OT

        Reason : common side in both the triangles

    8) By RHS congruency test

Step-by-step explanation:

A) <em>The given coordinates are (2,0) (4,3) and (5,2).</em>

<em>The transformation is (x,y) -> (x,-y) -> (x-5,y-2)</em>

For above all points;

(2,0) -> (2,0) -> (2-5,0-2) -> (-3,-2)

(4,3) -> (4,-3) -> (4-5,(-3)-2) -> (-1,-5)

(5,2) -> (5,-2) -> (5-5,(-2)-2) -> (0,-4)

Thus, the transformed points are;

W'(-3,-2)  X'(-1,-5)  Y'(0,-4)

B)<em> 2) It given that OT is perpendicular to AB, thus both </em><em>∠BTO and ∠ATO are      equal to 90 degrees.</em>

<em>4) The above statement is given.</em>

<em>5) The reason is T is midpoint, this means statement is regarding lengths of AT and BT.</em>

<em>Since T is midpoint, </em><em>AT = BT</em>

<em>6) The side </em><em>OT is contained in both the triangles.</em>

<em>8) Since one right angle is equal, Both lengths are equal and one side is common, the above two triangles are congruent by </em><em>RHS congruency test.</em>

One dozen students each drop a brass tack six times from a height of six inches onto a level hard surface. They record the numbe
pshichka [43]

Experimental Probability = 2/3

To find the experimental probability that the tack lands point-up for student 4, we can use the following equation

\frac{Point-up}{Attempts}\\\frac{4}{6} or\frac{2}{3}

If this helped you a Brainliest would be appreciated!
