Answer:

0.2109 or 21.09%

Step-by-step explanation:

In order to maintain the same price after two days, the stock must go up (U) on two days and go down (D) on two days, the sample space for this event is:

S={UUDD, UDUD, UDDU, DDUU, DUDU, DUUD}

There are 6 equally likely possible outcomes. The probability that the price of the stock will be the same as it is today is:

$P =6* (0.25*0.25*0.75*0.75)\\P=0.2109=21.09\%$

The probability is 0.2109 or 21.09%.

Tell whether the pair of polygons is similar. Explain why or why not. (3 points) I get the general idea of this but I’m having t

masha68 [24]

Answer:

PQRS and TUVW are similar.

Step-by-step explanation:

We are give two polygons.

Sides of first polygon are :

PQ = 8 ft

QR= 13ft

RS = 8ft

PS = 13ft.

Sides of second polygon:

TW = 2.4 ft

TU = 5.2 ft

UV = 2.4 ft

VW = 5.2 ft.

We can see that PQRS and TUVW are parallelograms.

Note: <em>If an angle of a parallelogram is equal to an angle of another parallelogram then parallelograms would be similar.</em>

We can see that <Q ≅ <T = 120°.

<h3>Therefore, PQRS and TUVW are similar.</h3>

The first row of a theater has 16 seats. There are 3 more seats in each row thereafter. How many seats are in the 25th row/

inessss [21]

Answer: 88

Step-by-step explanation:

Given

The first row has 16 seats

then there are 3 more seats in each row

this follows an AP with the first term $a=16$ and common difference $d=3$

So, no of seats in the 25 th row is

$\Rightarrow a_{25}=a+24d\\\Rightarrow a_{25}=16+3\times 24\\\Rightarrow a_{25}=88$

Thus, there are 88 seats in the 25 th row
