Answer:
170%
Step-by-step explanation:
So I am not 100% certain. But I think it is A.
Istance squared = (X2 - X1)^2 + (Y2 - Y1)^2
<span>distance squared = (-2 - 3)^2 + (4 - -2)^2 </span>
<span>distance squared = (-5)^2 + (6)^2 </span>
<span>distance squared = 25 + 36 </span>
<span>distance squared = 61 </span>
<span>Therefore; distance = square root of 61 = 7.8 approximately </span>
<span>---- </span>
<span>since each unit represents 5 miles: </span>
<span>distance (actual) = 7.8 * 5 = 39 miles</span>
Given that figure A with radius of 2 inches is dilated to form figure B, the radius of B will be given by:
Radius B=(radius A)×(scale factor)
but
scale factor=4
thus
Radius of B will be:
2×4
=8 inches
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%.
