Answer:
8m
Step-by-step explanation:
The area of a square is length*width.
We can square root the area to get the length of each side. Since the shape is a <em>square</em>, the lengths are the same.
=8
One side is <u>8m</u>.

Answer:
p-value: 1.000
There is enough evidence at the 1% level of significance to suggest that the proportions are not equal.
Step-by-step explanation:
We will be conducting a difference of 2 proportions hypothesis test
The hypothesis for this test is:
H_0: p1 - p2=0
H_a: p1 - p2 ≠0
(p1 ) = 252/300 = 0.84
(p2) = 195/300 = 0.65
This is a 2 tailed test with a significance level of 1%. So our critical values are: z > 2.575 and z < -2.575

Answer:
A.
Step-by-step explanation:
1. The standard form of the equation of a circle is
2. To find the center we require the midpoint of the 2 given points
center =
=(-5,8)
3. The radius is the distance from the centre to either of the 2 given points calculate the radius using the distance formula
