Hey there!!
How do you find slopes?
Ans - In order to find slop, we will need to use the slop formula which is
( y₂ - y₁ ) / ( x₂ - x₁ )
Now let's take two points on the graph
I will take the points ( -3 , 1 ) and ( 2 , -3 )
In this y₂ = -3 , y₁ = 1 and x₂ = 2 , x₁ = -3
Now let's plug in these values :
( - 3 - 1 ) / ( 2 + 3 )
( - 4 / 5 ) = slope
Hence, the answer is -4/5
Hope my answer helps!
Answer:
c)
<em>The probability of a player weighing more than 238 </em>
<em>P( X > 238) = 0.0174</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given mean of the normally distribution = 195 pounds
Given standard deviation of the normally distribution
= 20 pounds.
<em>Let 'x' be the random variable of the normally distribution</em>
Let X = 238
<u><em>Step(ii):</em></u>-
<em>The probability of a player weighing more than 238</em>
<em>P( X > 238) = P( Z> 2.15)</em>
= 1 - P( Z < 2.15)
= 1 - ( 0.5 + A(2.15)
= 1 - 0.5 - A(2.15)
= 0.5 - 0.4821 ( from normal table)
= 0.0174
<em>The probability of a player weighing more than 238 </em>
<em>P( X > 238) = 0.0174</em>
