Answer:
Step-by-step explanation:
We are asked to find the slope of a line. The slope tells us the steepness and direction of a line. It is found by dividing the change in y by the change in x.
In this formula, (x₁, y₁) and (x₂, y₂) are the points the line passes through. We are given the points (-6, 11) and (15,20). If we match a value with its corresponding variable, we see that:
- x₁ = -6
- y₁ = 11
- x₂ = 15
- y₂ = 20
Substitute the values into the formula.
Solve the numerator.
Solve the denominator. 2 back to back negative signs become a positive sign.
Simplify the fraction. 3 divides evenly into the numerator and denominator.
The slope of the line is <u>3/7.</u>
Answer:
<em> 99% of the confidence level of the mean WR score for all convicted drug dealers </em>
<em>(37.4544, 40.5456)</em>
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the sample size 'n' = 100
Given that the mean of the sample(x⁻) = 39
Given a standard deviation of the sample (σ) = 6
Level of significance = 0.01 or 99%
<u><em>Step(ii):-</em></u>
<em> 99% of the confidence level of the mean WR score for all convicted drug dealers </em>
<em></em><em></em>
<em></em><em></em>
<em>(39 - 1.5456 , 39+1.5456)</em>
<em>(37.4544, 40.5456)</em>
<u><em>Final answer:-</em></u>
<em> 99% of the confidence level of the mean WR score for all convicted drug dealers </em>
<em>(37.4544, 40.5456)</em>
<em></em>
