Answer:

16:40, 0.4

Step-by-step explanation:

experimental probability would be a ratio consisting of the number of times the coin lands on heads to the total number of times the coin is flipped so it would be 16 to 40 or simply 16:40

theoretical probability would be a way to show the likeliness of the coin landing on heads and can be found by dividing the number of flips that is expected to land heads up by the total number of flips so you divide 16 by 40 which equals 0.4

Delicious77 [7]

Answer:

√ 18 = 3 √2

Step-by-step explanation:

So 24-6 is 18 and then the square root of that. You have to divide by a perfect square and the largest perfect square that can go into 18 is nine because 3x3. 9 can go into 18 2 times so it is 2 radical 9

Given the triangle

PQR

with points

P(8,0)

Q(6,2)

R(-2,-4)

And the triangle

P'Q'R'

with points

P'(4,0)

Q'(3,1)

R'(-1,-2)

Part A. Scale factor

Using the vertex

P( 8, 0)

P'(4,0)

the dilatation factor is given by

$\frac{4}{8}=\frac{1}{2}$

The triangle has a dilatation factor of 1/2

Part B:

P''Q''R'' after using P'Q'R' reflected about the y axis

to make a reflection over the y axis

coordinates (x,y) turn into coordinates (-x,y)

as follows

$P^{\prime}(4,0)\rightarrow P^{\prime\prime}(-4,0)$ $Q^{\prime}(3,1)\rightarrow Q^{\prime\prime}(-3,1)$ $R^{\prime}(-1,-2)\rightarrow R^{\prime\prime}(1,-2)$

Then triangle P''Q''R'' has coordinates

P''(-4,0)

Q''(-3,1)

R''(1,-2)

Part C:

PQR is congruent to P''Q''R''?

Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal.

Then the triangles are not congruent
