At a z-score of 1.80, the percentage of the scores that are better than yours is equal to 3.59%.
<h3>What is a z-score?</h3>
In Mathematics, a z-score is sometimes referred to as a z-value or standard score and it can be defined as a measure of the distance between a raw score and the mean, when standard deviation units are used.
<h3>How to determine the percentage?</h3>
Mathematically, the z-score of a given sample score in a normal distribution can be calculated by using this formula:
Z-score = (x - μ)/σ
Where:
- x represents the sample score.
- σ represents the standard deviation.
- μ represents the mean score.
Since a score of 85 on a test corresponds to a z-score of 1.80, the percentage of the scores that are better than yours is given by:
P(x > 85) = P(z > 1.80)
P(z > 1.80) = 0.0359
P(z > 1.80) = 3.59%.

if the lower pointvis 56 the dot line will be 55.5
Answer:
I'm not sure what that U is for.
The answer is 459,461 These two do add to 920
Step-by-step explanation:
Remark
I'm going to make sure you are using consecutive odd numbers.
Let the smaller number = 2x - 1
Let the larger number = 2x + 1
Equation
2x - 1 + 2x + 1 = 920
4x = 920
x = 230
The consecutive numbers are 2*230 - 1 = 459
and 2*230 + 1 = 461
