Answer:

85 square inches  

Step-by-step explanation:

I think your question missed key information, allow me to add in and hope it will fit the orginal one. Please have a look at the attached photo

My answer:

From the question, four congruent equilateral triangles with the following information:

  • The height: 6.06 inches
  • The base : 7 inches

=> The area of the quilateral triangle is:

=1/2*the base*the height

= 1/2*60.6*7

= 21.21 square inches

=> the surface area of Abby's decoration is:

= 4 * The area of the quilateral triangle

= 4*21.21

= 84.84 square inches  

≈ 85 square inches  

Hope it will find you well.

Assume the sample variances to be continuous measurements. Find the probability that a random sample of 36 observations, from a
frez [133]

Answer:

0.02566

0.972559

Step-by-step explanation:

Given that :

Sample size (n) = 36

σ² = 6

sample variance S^2

a) greater than 9.1;

b) between 3.5 and 10.5.

The degree do freedom (df) = n - 1

S² > 9.1

P(S² > 9.1) = X² > ((n - 1) * S²) / 6

P(S² > 9.1) = ((36 - 1) * 9.1) / 6

P(S² > 9.1) = (35 * 9.1) / 6

P(S² > 9.1) = 53.083

P(X² > 53.08) = 0.02566 ( chi square distribution calculator)

b) between 3.5 and 10.5.

((36 - 1) * 3.5) / 6 ≤ S² ≤ ((36 - 1) * 10.5) / 6

20.416666 ≤ S² ≤ 61.25

Using the Chisquare distribution calculator :

P(X² > 20.42) = 0.9765

P(X² > 61.25) = 0.003941

Hence,

0.9765 - 0.003941 = 0.972559

kozerog [31]

Answer:

The given situation is an example of ultimatum game.

Explanation:

The ultimatum game is a popular experiment. It is widely used in economic experiments. In this game two people are matched randomly, one player as a proposer and one as a responder. They are told they would play a game exactly once. The proposer is given an amount of money and he has the task to split or divide that amount between himself and the responder. When the proposer conveys the decision, the respondent then decides whether to accept or reject it. If the responder accepts, then both earn the amount split per the proposer's suggestion. If responder rejects then both the proposer and responder receive nothing.

For example a player is given a sum of money, $ 20.  He is called proposer. He is told to offer some endowed amount (from $1 to $20) to the other player who is responder. If responder accepts this amount offer they both keep that money but if the responder rejects the offer then both players get nothing.
