Answer:
Step-by-step explanation:
okay so you can take any two points 1 x one y in the form (x, y) and (x, y) so
(2, 5) and (4, 1)
then use the slope formula y2-y1/ x2 -x1
1-5+=4
4-2=2
slope equals 4/2 simplified equals 2
I THINKKKKK!

Population mean, 
= $23,500
Sample mean,
= $24,500
Sample standard deviation,s = $2,800
Sample size, n = 146
Confidence interval:
Putting the values, we get,
The confidence interval is (24116.3878,24883.6122).
Answer:
44 cm
Step-by-step explanation:
The area of a square is the square of the side length. This means the side length is the square root of the area.
s = √A = √(121 cm²) = 11 cm
The perimeter of a square is the sum of its side lengths. There are 4 equal-length sides, so the perimeter is 4 times the length of one side:
P = 4s = 4(11 cm)
P = 44 cm
The perimeter of the square is 44 cm.
