Answer:

See Below.

Step-by-step explanation:

We are given that PQRS is a parallelogram, where X and Y are points on the diagonal QS such that SX = QY.

And we want to prove that quadrilateral PXRY is a parallelogram.

Since PQRS is a parallelogram, its diagonals bisect each other. Let the center point be K. In other words:

SK=QK\text{ and } PK = RK

SK is the sum of SX and XK. Likewise, QK is the sum of QY and YK:

SK=SX+XK\text{ and } QK=QY+YK

Since SK = QK:

SX+XK=QY+YK

And since we are given that SX = QY:

XK=YK

So we now have:

XK=YK\text{ and } PK=RK

Since XY bisects RP and RP bisects XY, PXRY is a parallelogram.

。o°✥✤✣  The answer to this is: ✣✤✥°o。

Join PROQ = OS (diagonals of a parallelogram bisect each other)

QY = SX OQ - QY = OS - SXOY = OX

In quadrilateral PXRYAO =  OXOX = OY

Thus, the diagonals of the quadrilateral

PXY are bisecting each other PXRY is a parallelogram.

Hope It Helped! :)

You flip a coin 100 times in the air and find that it lands on heads 65 times. Determine the theoretical and experimental probab
scoundrel [369]

Answer:

The experimental probability --> \frac{13}{20}

The theoretical probability --> \frac{1}{2}

Step-by-step explanation:

<u>Key skills needed: Experimental vs theoretical probability, Fractions</u>

1) The first thing you need to understand is experimental probability vs theoretical probability. (Do not include this in your work!!)

- Theoretical probability is based on simple reasoning

- Experimental probability is based on the results a person gets (so the experiment you did by flipping the coin)

2) Now with this, let's start solving:

  1. Experimental probability ---> \frac{heads}{total} -->  You flipped the coin  a total of 100 times, so the denominator would be 100. 65 of those would be heads so 65 is our numerator.
  2. So our experimental probability is --> \frac{65}{100} --> Both have the factor of 5, so take the factor of 5 out of the numerator and denominator and you will get --> \frac{13}{20}
  3. Now onto theoretical probability --> \frac{heads}{total} --> There are 2 faces of a coin, 1 side is heads, and 1 side is tails --> The total number of faces is 2, so 2 is our denominator. There is only 1 side that is heads, so 1 is the numerator. This means  --> Our theoretical probability is \frac{1}{2}

<em>Hope you understood and have a nice day!! :D</em>

PLEASE HELP For the expression below, write two other equivalent expressions using different terms. Make sure one is fully simpl
Julli [10]

Given:

The given expression is

-4(x+2)-2x+4

To find:

The two other equivalent expressions.

Solution:

We have,

-4(x+2)-2x+4

Using distributive property, we get

=-4(x)-4(2)-2x+4

=-4x-8-2x+4

So, one equivalent expression is -4x-8-2x+4.

On further simplification, we get

=(-4x-2x)+(-8+4)

=6x-4

Therefore, the second and fully simplified equivalent expression is 6x-4.

At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter.
Alexus [3.1K]

Answer: $110


Step-by-step explanation:

Given: At Simba Travel Agency, the price of a climbing trip to Mount Kilimanjaro includes an initial fee plus a constant fee per meter.

F(d)models the fee (in dollars) for climbing d meters.

F(d)=110+0.12d

To find the initial amount, substitute d=0 int the above function, we get

F(0)=110+0.12(0)=110


Hence, the initial fee= $110.
