rusak2 [61]

Answer:

The answer is 2.0190

Step-by-step explanation:

<em>From the given question,</em>

<em>We recall that,</em>

<em>p = 141/241 = 0.5850</em>

<em>so, p = 0.5</em>

<em>The Hypothesis is:</em>

<em>H₀ : P = 0.5, this means that  H0:50% of the games played will be won</em>

<em>vs</em>

<em>H₁ : P > 0.5, This indicates that, win is greater than 0.5 due to home field advantages.</em>

<em>n=241,x=141</em>

<em>Then,</em>

<em>SD(p)=√(p*q/n)=√(0.5*0.5/141)=0.0421</em>

<em>z = p - p/ SD (p) = 0.5850 - 0.5/0.0421 = 0.085/0.0421 =2.0190</em>

<em>therefore, there is strong evidence that there is home field advantages in professional football.</em>

Sonja [21]

Answer:

SAS Postulate

Step-by-step explanation:

You can use the SAS (side, angle, side) postulate that says "if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent"

Side AB is proportionate to DE and

Side AC is proportionate to DF.

Angle A and Angle D are the same; and is between the two sides

I hope this helps.
