Answer:
y = -x + 1
Step-by-step explanation:
y = mx + b
Find two point on the graph (0,1) (4,-2); 1 is the y intercept
y = mx + 1
=
y = -x + 1
<em>y-intercept</em><em> </em><em>is</em><em> </em><em>where</em><em> </em><em>the</em><em> </em><em>line</em><em> </em><em>on</em><em> </em><em>your</em><em> </em><em>graph</em><em> </em><em>crosses</em><em> </em><em>through</em><em> </em><em>the</em><em> </em><em>y-axis</em>
Answer:
<em> The probability that the average score of the 81 golfers exceeded 76</em>
<em>P(x⁻≤ 76) = 0.9772 </em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given mean of the Population (μ) = 75
Given standard deviation of the Population (σ) = 4.5
Given size 'n' =81
Let 'X' be the random variable in Normal distribution
Z = 2
<u><em>Step(ii):-</em></u>
<em>The probability that the average score of the 81 golfers exceeded 76</em>
<em>P(x⁻≤ 76) = P( Z≤ 2)</em>
<em> </em><em>= 1 - P(Z>2)</em>
<em> = 1 - ( 0.5 - A(2))</em>
<em> = 0.5 + A(2)</em>
<em> = 0.5 +0.4772</em>
<em> = 0.9772</em>
<em> The probability that the average score of the 81 golfers exceeded 76</em>
<em>P(x⁻≤ 76) = 0.9772 </em>
