The true speed and direction of the football thrown by the  quarterback is 30.185 mph and 9⁰ respectively. 
<h3>
Relative velocity of the football</h3>
The true speed and direction of the football is determined by applying the concept of relative velocity.
Vr/w = Vb - Vw
where;
- Vr/w is the velocity of the football with respect to the wind
- Vb is the velocity of the football
- Vw is the velocity of the wind
Vr/w = 41 mph - 11 mph = 30 mph
The direction speed can be determined by sketching a triangle
Direction of the speed, θ = (360 - 339) - (180 - 168)
                                        θ = 21 - 12 = 9⁰
<h3>Resultant speed;</h3>
R² = 41² + 11² - 2(41 x 11 x cos9)
R² = 911.105
R = √911.105
R = 30.185 mph
Thus, the true speed and direction of the football thrown by the  quarterback is 30.185 mph and 9⁰ respectively.

Answer:
P(X  74) = 0.3707
 74) = 0.3707
Step-by-step explanation:
We are given that the score of golfers for a particular course follows a normal distribution that has a mean of 73 and a standard deviation of 3.
Let X = Score of golfers
So, X ~ N( )
)
The z score probability distribution is given by;
            Z =  ~ N(0,1)
 ~ N(0,1)
where,  = population mean = 73
 = population mean = 73
             = standard deviation = 3
 = standard deviation = 3
So, the probability that the score of golfer is at least 74 is given by = P(X  74)
 74)
  P(X  74) = P(
 74) = P(  
  
  ) = P(Z
 ) = P(Z  0.33) = 1 - P(Z < 0.33)
 0.33) = 1 - P(Z < 0.33) 
                                                =  1 - 0.62930 = 0.3707                   
Therefore, the probability that the score of golfer is at least 74 is 0.3707 .
