Answer:
7 units
Step-by-step explanation:
If the line is a straight line, count the number of units in between the two pints of the line.
If you count the units between the two pints on your screen, you will see that the answer is 7 units. This is because there are 7 units in between the two points of the line.
Answer:
(5.240 ; 8.760)
Step-by-step explanation:
Given :
Sample mean, xbar = 7
Standard deviation, s = 2.29
Sample size, n = 9
95% confidence interval for the population mean :
Confidence interval :
Xbar ± Margin of error
Margin of Error = Tcritical * s/sqrt(n)
Tcritical at 0.05 ; df = 8 = 2.306
Margin of Error = 2.306 * 2.29/sqrt(9)
Margin of Error = 1.760
Lower boundary = (7 - 1.760) = 5.240
Upper boundary = (7 + 1.760) = 8.760
(5.240 ; 8.760)
Answer:
y = -x + 2
Step-by-step explanation:
The equation of a line in a slope intercept form is given as :
, where m is the gradient and c, y - intercept.
First, let us find the gradient, m of the line that passes through the points, (4,-2) and (-5,7) using the relation ;
By substitution we get
We substitute any of the points and the value of m into y= mx + c to find the value for c.
Adding 4 to both sides.
Hence the equation of the line is :
y = -x +2
