Answer: 14
Step-by-step explanation:
Since they said find the mean
You are suppose to add up all the numbers then divide it by how many numbers are there.
The z-score of a certain data point in the given statistical data is calculated through the equation,
z-score = (x - m) / sd
where x is the data point, m is the mean and sd is the standard deviation.
Substituting the known values,
z-score = (51.8 - 52.3) / 1.8
z-score = -0.277
Rounding the answer to the nearest tenth will give an answer of -0.3.
Answer:
2.75x+122.5
Step-by-step explanation:
Horse=x
Stork=x+70
Whale=3/4(x+70) = 0.75(x+70) = 0.75x+52.5
x+x=70+0.75x+52.5
2.75x+122.5
