Given
The equation in the form
Find the factor of the above equation
To proof
factoring the above equation
we get
now sloving the equation we get the value
x² = 5
x² = -100
The factor of the equation is
Hence proved
From the problem, we are given
x1 - x 2 = 10 cm
s of (x1 - x2)i = 6 cm
The null hypothesis is that there is no significant difference between the height of males of the two neighborhoods.
For the null hypothesis to be rejected, this condition must be met
u1 - u2 ≠ 0
For a normal distribution
u = x + z s / √n
where z depends on the confidence interval (CI)
If
CI = 67%, z = 0.16
CI = 95%, z = 0.025
CI = 99.7%, z = 0.0015
CI = 100%, z = 0
So,
u1 - u2 = x1 + z s1 √n - (x2 - z s2 /√n )
Substituting the given values and trying out the different values of z for different confidence intervals, the CI that would meet the required condition is
CI = 95%
So, the answer is
<span>The null hypothesis must be rejected if we choose the 95% confidence level.</span>
Basically just multiply the sides that are the same so 12 x 12 and than 8x8 Than 2x2 and what I get I think u add them all together
The population of the town in 36 years would be 8000.
<h3>What would be the population of the town in 36 years?</h3>
The formula that can be used to determine the town's population is:
FV = P (1 + r)^n
Where:
- FV = Future value
- P = Present value
- R = rate of growth = 100%
- N = number of years = 36/9 = 4
500 x 2^4 = 8000

1+1 is 2
I hope that helped
