Answer:

A) Harry Stains his shirt during the dinner.

Step-by-step explanation:

1/5 = 0.2 which is a 20% probability of Harry staining his shirt during dinner.

Larry's probability of staining his shirt during dinner is 15%. Since Harry's probability of staining his shirt is higher, he will more likely stain his shirt.

spin [16.1K]

Answer:

a)125970

b)95040

c)35640

Step-by-step explanation:

a) selecting 12 player from 20 players can be one in ^{20} C_{12}

 ^{20} C_{12} = \frac{20!}{12!X (20-12)!}

          =  \frac{20!}{12!X8!}

          = 125970

b) since each position has an identity permutations can be used so

   Number of ways = ^{12} P_{5}

                                = \frac{12!}{(12-5)!}

                                = \frac{12!}{7!}

                                = 95040

c) coach permutes 4 players for position other than centers in  ^{12}P_{4} ways and selects center in 3 ways

  so, number of ways = ^{12}P_{4}X3

                                     =\frac{12!}{8!}X3

                                     =35640

Triangle abc and xyz are congruent ,/_A is one half the size of /_B,/_y is 90° ./_c and /_z each have a measure of 45°.What is t
Rashid [163]

Answer:

∠a = 45°

Step-by-step explanation:

We are told that △abc and △xyz are congruent.

Thus;

∠a = ∠x

∠b = ∠y

∠c = ∠z

We are given;

∠y = 90°

Thus, ∠b = 90°

Now,we are told that ∠a is one half the size of ∠b.

Thus; ∠a = ½ × ∠b

∠a = ½ × 90

∠a = 45°

Consider the statements below. Which are not propositions? Mark all that apply.
Troyanec [42]

Answer:

In Idaho, there are 15 temples for the Church of Jesus Christ of Latter-day Saints.

A delicious chocolate cake.

The great and spacious building.

3+5=8

5+3=53

Step-by-step explanation:

To determine which statement is a propositions or not first, we need to define the concept of preposition:

<em>A statement that can be either true or false.</em>

That means it should declare unequivocal information about something.

A question is not declaring something to be true or false. Therefore, it is not a proposition.

The recommendation of "should get" is not a direct statement.

No way! is not referring to anything to be either true or false.
