Answer:
The points which satisfy the given lines is ( 1 , 1 )
Step-by-step explanation:
Given as :
The equation of lines is
y = 3 x - 2 ........ 1 And
y = - 2 x + 3 ........ 2
From equation given
3 x - 2 = - 2 x + 3
Or , 3 x + 2 x = 3 +2
Or, 5 x = 5
So , x = = 1
Put the value of x in eq 1
So, y = 3 ( 1 ) - 2
Or, y = 3 - 2 = 1
∴, the points ( x , y ) = ( 1 , 1 )
Hence The points which satisfy the given lines is ( 1 , 1 ) Answer
Answer:
y = 1/2x - 4
Step-by-step explanation:
The x-intercept is when y = 0, so it would be:
-x + 2 * 0 = 4
-x = 4
x = -4
That means the x-intercept is (0, -4)
The parallel line would have the same slope as this one, so:
The parallel line has a slope of 1/2
So now you need to find the equation of a line that has a slope of 1/2 and passes through the point (0, -4)
Put it in point slope form:
y - (-4) = 1/2(x - 0)
y + 4 = 1/2x
y = 1/2x - 4
Answer: The point estimate of the population mean is <u>25</u>.
The margin of error for the confidence interval is <u>3</u> .
Step-by-step explanation:
The confidence interval for population mean is given by :-
, here is the point estimate of the population mean and E is the margin of error .
As per given , we have
Lower bound of CI = (1)
Upper bound of CI = (2)
Add (1) and (2) , we get
Subtract (1) from (2) , we get
Hence, the point estimate of the population mean is <u>25</u>.
The margin of error for the confidence interval is <u>3</u> .
