The sample space of picking a 2
Alchen [17]

Answer:

Pr = \frac{1}{15}

Step-by-step explanation:

Given

See attachment for sample space

Required

P(1\ Y\ and\ 1\ P)

From the attached sample space, we have:

n(S) =30 ---- total outcomes

n(PY) = 2 --- outcomes with 1 Y and 1 P = 2 i.e. (P,Y) and (Y,P)

So, the required probability is:

Pr = \frac{n(PY)}{n(S)}

Pr = \frac{2}{30}

Pr = \frac{1}{15}

<em>The error is that; Carlos omitted the numerator</em>

Complete each congruency statement and name the rule used. If you cannot show the triangles are congruent from the given informa
irinina [24]

Answer:

The correct answer is;

ΔANT ≅ ΔFLE by the SIde-Side-Side (SSS) rule of congruency

Step-by-step explanation:

The given information are;

Segment TN is congruent ts segment EL

Segment TA is congruent ts segment EF

Segment AN is congruent ts segment FL

Therefore, triangle ΔANT is congruent to ΔFLE by the Side-Side-Side (SSS) rule of congruency

One of the rule used to serve as proof that two or more triangles are congruent, is the Side-Side-Side (SSS) rule of congruency. The Side-Side-Side rule of congruency states that if the dimensions of the three sides of one triangle are equal to the dimensions of the three sides of another triangle, the two triangles are congruent.

Therefore, the correct option is ΔANT ≅ ΔFLE by the Side-Side-Side (SSS) rule of congruency

I need an answer to this big question
Kisachek [45]

Answer:

RS + ST = RT

23 - 2x     +     9x - 5     =     39

18 + 7x = 39

7x = 39 - 18 = 21

x= 21/7

x = 3

RS = 23 - 2x (given)

RS = 23 - 2(3)

     = 23 - 6

RS = 17
