By factor decomposition, area of a square and power and root properties, the length of the side is between 72 yards and 76 yards. (Correct choice: B)

<h3>What integers are the limits between the length of an equivalent square side of a given area?</h3>

The area of a triangle is equal to the square of its side length and the area of land is a composite number, that is, a product of prime numbers. By factor decomposition, the equivalent form of 5,280 square yards is:

5,280 = 2⁵ × 3 × 5 × 11

Then, the equivalent side is equal to the square product of the product:

x = √(2⁵ × 3 × 5 × 11)

x = √(2⁴) × √(2 × 3 × 5 × 11)

x = 2² × √(2 × 3 × 5 × 11)

x = 4√330

As for √330 is between √324 = 18 and √361 = 19, then the length of the side is between 72 yards and 76 yards.

PLS HELP! 7x +10y= -23<br><br> 7x + 6y = - 39

mote1985 [20]

4y = -23 + 39
4y = 16
y = 4

Sub y = 4 into equation 2
7x + 6(4) = -39
7x + 24 = -39
7x = -39-24
7x = -63
x = -9

x = -9
y = 4

Using the z-distribution, the test statistic is:

c) -2.63.

<h3>What are the hypothesis tested?</h3>

At the null hypothesis we test if the means are equal, equivalent to a subtraction of 0, hence:

$H_0: \mu_D - \mu_C = 0$

At the alternative hypothesis, we test if they are different, hence:

$H_1: \mu_D - \mu_C \neq 0$

<h3>What are the mean and the standard error for the distribution of differences?</h3>

For each sample, they are given as follows:

$\mu_D = 12, s_D = \frac{5.2}{\sqrt{73}} = 0.6086$ .

$\mu_C = 14, s_C = \frac{4.1}{\sqrt{81}} = 0.4556$ .

For the distribution of differences, it is given by:

$\overline{x} = \mu_D - \mu_C = 12 - 14 = -2$ .

$s = \sqrt{s_D^2 + s_C^2} = \sqrt{0.6086^2 + 0.4556^2} = 0.76$

<h3>What is the test statistic?</h3>

The test statistic is given by:

$z = \frac{\overline{x} - \mu}{s}$

In which $\mu = 0$ is the value tested at the null hypothesis.

Hence:

$z = \frac{\overline{x} - \mu}{s}$

$z = \frac{-2 - 0}{0.76}$

z = -2.63.
