Answer:
The answer to your question is y = -7/2x -13/2
Step-by-step explanation:
Point = (-3, 4)
Line -2x + 7y = -3
Process
1.- Solve equation for y to find the slope of the perpendicular line
7y = 2x - 3
y = 2/7 x - 3/7
slope = 2/7
Slope of the perpendicular line = -7/2
2.- Find the equation of the new line
y - y1 = m(x - x1)
y - 4 = -7/2(x + 3)
y - 4 = -7/2x - 21/2
y = -7/2x - 21/2 + 4
y = -7/2x -21/2 + 8/2
3.- Result
y = -7/2x -13/2

Answer:
95% of confidence intervals are
(197.706 , 198.294)
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given sample size 'n'=100
Mean of the sample x⁻ = 198
The standard deviation of the Americans =15
95% of confidence intervals are determined by
Level of significance = 0.05
Z₀.₀₅ = 1.96
=
= ( 198 -0.294 ,198 +0.294)
= (197.706 , 198.294)
95% of confidence intervals are
(197.706 , 198.294)

Step-by-step explanation:
Answer:
She will have a loss of $ 120
Step-by-step explanation:
Purchase price of car = $ 3000
20% of 3000 =
= 20 * 30
= $ 600
Selling price = 3000 + 600 = $ 3600
Reduction price = 20% of 3600
= 20 * 36
= $ 720
Current selling price after reduction = 3600 - 720
= $ 2880
Loss = 3000 - 2880
= $ 120
