Answer:
The percentage of her shots that will travel less than 180 yards is approximately 15.9%
Step-by-step explanation:
First it will be required to find the standard or z-score from the following formula
Where:
z = z or standard score
x = value that is observed = 180 yards
μ = Sample mean = 200 yards
σ = Sample standard deviation yards
Plugging the values, we have;
Therefore, the probability that her shots will travel less than 180 is given by the relation;
p( x < 180 yards) = p(z < -1) = 0.15866
Therefore, the percentage of her shots that will travel less than 180 = 0.15866 × 100
= 15.866% ≈ 15.9%.

Answer:
x=1+√5 or x=1−√5
Step-by-step explanation:
Answer:y = 65x/z
Step-by-step explanation:
Suppose y varies directly with x and inversely with z. It means that as y increases or decreases, y increases or decreases while z decreases or increases respectively.
In order to remove the variation symbol and replace with an equation symbol, we would introduce a constant of variation, k. It becomes
y = kx/z
When x= 65 and z=5, then y= 26. We would substitute these value to get the constant of variation, k. It becomes
26 = 65k/5
65k = 65
k = 1
The equation of combined variation will be
y = 65x/z
