Answer:
y = 1/2x +2
Step-by-step explanation:
y-y1= m (x-x1)
first find slope
m= 4-1 / 4 - (-2)
m= 3 / 4+2
m= 3/ 6
m = 1/2
you can pick any of the two points to solve for point slope form
y-4 = 1/2 (x-4)
y-4= 1/2x -2
add 4 on both sides
y = 1/2x +2
y-1= 1/2 (x- (-2))
y-1= 1/2 (x+2)
y-1= 1/2x +1
add 1 on both sides
y= 1/2x +2
you should get the same answer with any of the two points you chose
you might want to use a calculator to solve this
if you want to use both points to make sure the answer is correct, you can
if you don't get the same answer with both points then u did something wrong during the equation.
Answer:
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).
Step-by-step explanation:
To find the interval, we can just make the conversion of the values from pounds to kilograms.
Each kilogram has 2.2 pounds. So, to realize the conversion from pounds to kilograms, we divide by 2.2.
Confidence interval: (102.3 pounds, 106.5 pounds).
102.3 pounds = 102.3/2.2 = 46.5 kilograms
106.5 pounds = 106.5/2.2 = 48.41 kilograms
The confidence interval for the mean weight of high school girls in kilograms would have been would have been (46.5, 48.41).
