Answer:
<u>The perimeter of the square is option E. 16√5 mm.</u>
<u>The area of the square is option A. 80 mm².</u>
Step-by-step explanation:
1. Let's calculate the perimeter of this square:
The perimeter of a square is the sum of its side 4 times, thus:
Perimeter = 4√5 + 4√5 + 4√5 + 4√5
<u>Perimeter = 16 √5</u>
<u>Perimeter = 4 * 4√5 = 16√5</u>
<u>The correct answer is option E. 16√5 mm</u>
2. Let's calculate the area of this square:
The area of a square is the length of its side squared, thus:
Area = (4√5)²
Area = 4√5 * 4√5
Area = (4 * 4 * √5 * √5)
Area = 16 * 5 = 80
<u>The correct answer is A. 80 mm²</u>
You get imaginary roots for this equation.

x=4+5i
Answer:
Step-by-step explanation:
Hello!
Suppose that the objective of the experiment is to test if a certain treatment modifies the mean of the population of interest.
If for example, the treatment is "new fertilizer" and the population of interest is "yield of wheat crops"
Then you'd expect that using the new fertilizer will at least modify the average yield of the wheat crops.
The hypotheses will be then
H₀: μ = μ₀
H₁: μ ≠ μ₀
Where μ₀ represents the known average yield of wheat crops. (is a value, for this exercise purpose there is no need to know it)
We know that the treatment modifies the population mean, i.e. the null hypothesis is false.
The sample we took to test whether or nor the new fertilizer works conducts us to believe, it does not affect, in other words, we fail to reject the null hypothesis.
Then we are in a situation where we failed to reject a false null hypothesis, this situation is known as <em><u>Type II error</u></em>.
I hope this helps!
Answer:
24
Step-by-step explanation:
6 divided by 1/4 is the same thing as 6 multiplied by 4, so the answer is 24.
