The equation for the determination of the z-score is shown below.
z-score = (x - μ) / σ
where x is the value in which we need to determine the z-score, μ is the mean or the average, and σ is the standard deviation.
Substituting the known values,
z-score = (1,030.00 - 1,200) / 100 = -1.7
Therefore, the z-score of 1,030 is -1.7.
Answer:
Brock completed approximately 38 pull ups in the initial stage of training.
Step-by-step explanation:
We are given the following information in the question:
Ration of pull ups and box jumps initially =
Ration of pull ups and box jumps later =
Number of box jumps completed in the end of training = 53
Total number of exercises done in the end = 2x + 7x = 9x
We use the concept of ratio.
Initially,
Total number of exercise = 5y + 4y
Thus, he completed approximately 38 pull ups in the initial stage of training.
