Answer:
The system has infinitely solutions
Step-by-step explanation:
we have
Multiply by 3 both sides
----> equation A
The equation A is a circle centered at origin with radius 
and
Divide by 5 both sides
----> equation B
The equation B is a circle centered at origin with radius
Equation A and Equation B are the same
Therefore
The system has infinitely solutions
using the given coordinates, the rectangle is 7 by 3 units
area = 7*3 = 21 square units
Answer:
Step-by-step explanation:
Given that Home sales has 95% confidence interval to estimate the average loss in home value.
a) If std deviation of losses doubles as 3000 from 1500, we have margin of error also increases. Because margin of error
= ±Critical value * Std error
= ±Critical value * Std dev/sqrt n
Hence we find that whenever std deviation increases the margin of error increases, for the same level of confidence.
b) Whenever confidence level increases, critical value increases and as a result margin of error increases. Hence by reducing from 95% to 90% confidence interval would be reduced. True
c) Instead of changing conf level, increasing sample size would give more reliale and accurate results.
The Answer Is -5. The Biggest Number Being 3 And The Smallest Is -8.
