Each coin has a head and a tail, therefore when you toss two coins, you have 4 possible outcomes. You have two heads in only one of these outcomes, while the other three have at least one tail.

The expected value of the game is the price paid/gained times the probability of loss/victory:

E = (1 / 4) · (-6) + (3 / 4) · (2)
   = -3 / 2 + 3 / 2
   = 0

Write the congruency statement for the triangles. _______In triangles MNO and JKL, there are two congruent sides and included an
mafiozo [28]

Answer:

ΔJKL ≅ ΔMNO by SAS

Step-by-step explanation:

The question is incomplete, the question is as following:

ΔMNO is shown.

Which Δ below can be shown to be congruent to ΔMNO with only the given information?

Name the postulate that justifies your answer (SAS, AAS, HL, ASA or SSS).

Write the congruency statement for the triangles.

And see the attached figure which represent ΔMNO

==========================================================

Check the given options to see which triangle from the option will be congruent to ΔMNO

1. In triangles MNO and ABC, there are two congruent sides and non-included angle - which mean (angle - side - side)

The (angle - side - side) Postulate does not exist because an angle and two sides does not guarantee that two triangles are congruent.

2. In triangles MNO and DEF, there are two congruent sides - there is not enough information

3. In triangles MNO and GHI, there are three congruent angles - which mean AAA (angle - angle - angle)

The AAA Postulate does not exist because an angle and two sides does not guarantee that two triangles are congruent. This postulate is used to prove the similarity between the triangles.

4. In triangles MNO and JKL, there are two congruent sides and included angle - SAS (side - angle - side)

MN ≅ JK , MO ≅ JL , ∠M ≅ ∠J

What equation can be used to find n, the number of nickels in the collection ?
Semenov [28]

Given, Bodhi has a collection of 175 dimes and nickel. If she has n numbers of nickel. Then,

The number of dimes coin= 175-n.

The collection is worth $13.30.

1 nickel is worth five cents. So, n nickel will worth 0.05n.

Similarly 1 dime is worth 10 cents. So, 175-n dimes will worth 0.1(175-n).

Since the total worth is $13.30. So, we can set the equation as follows:

0.1(175-n)+0.05n=13.13.

Hence, the last option is the correct choice.

inna [77]

Answer:

You could solve this by taking the y value and adding it to the multiplied rate.

For example: For Jill's 6 year mark, the equation would be 11(6) + 15.

Hope this makes sense, don't hesitate to ask for clarification on a certain part of the answer.
