Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange 3x - 4y = 7 into this form
Subtract 3x from both sides
- 4y = - 3x + 7 ( divide all terms by - 4 )
y = x -
← in slope- intercept form
with slope =
• Parallel lines have equal slopes, hence
y = x + c ← is the partial equation of the parallel line
To find c substitute (- 4, - 2) into the partial equation
- 2 = - 3 + c ⇒ c = - 2 + 3 = 1
y = x + 1 ← in slope- intercept form
Multiply all terms by 4
4y = 3x + 4 ( subtract 4 from both sides )
4y - 4 = 3x ( subtract 4y from both sides )
- 4 = 3x - 4y, that is
3x - 4y = - 4 ← in standard form
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>
