Imagine you conducted a study to look at the association between whether an expectant mother eats breakfast (or not) and the gen

der of her baby. Cramér's V = .22. How would you interpret this value? (Hint: Cramér's V can range between 0 and 1.) There was a small to medium association between baby gender and whether the mother ate breakfast every day. 22% of the variation in frequency counts of baby gender (boy or girl) can be explained by whether or not the mother ate breakfast every day. 2.2% of the variation in frequency counts of baby gender (boy or girl) can be explained by whether or not the mother ate breakfast every day. There is a medium to large association between the gender of the baby and whether or not the mother ate breakfast every day.

Find the area of the regular hexagon.
NeTakaya

Answer:

1) The area of the regular hexagon is approximately 11.256 unit²

2) The coordinates of the center is (2, 3)

3) The base length is approximately 2.08 units

4) The height of the hexagon is approximately 3.61 units

Step-by-step explanation:

1) The length, lₐ, of the apothem is given as follows;

l_a = \sqrt{\left (y_{2}-y_{1}  \right )^{2}+\left (x_{2}-x_{1}  \right )^{2}}

Therefore, for the apothem having coordinates, (2, 3), and (3, 1.5), we have;

l_a = \sqrt{\left (3-1.5  \right )^{2}+\left (2-3  \right )^{2}} = \sqrt{1.5^2 + (-1)^2} =\sqrt{3.25}

The length of half half of one side, S/2 = a × tan(30°) = √(3.25)/√3

The length of the base = 2 × √(3.25)/√3 ≈ 2.082 units

The perimeter, P = 6 × 2× √(3.25)/√3

The area, A = 1/2 × P × a = 1/2 × 6 × 2 × √(3.25)/√3 × √3.25 = (13·√3)/2

A = (13·√3)/2 unit²

The area of the regular hexagon, A =  (13·√3)/2 unit² ≈ 11.256 unit²

2) The coordinates of the center = (2, 3)

3) The base, 'b', length by Pythagorean theorem is given as follows;

b = √(a² + (S/2)²) = √((√(3.25))² + (√(3.25)/√3)²) = √(3.25 + 3.25/3) = √(13/3) = (√39)/3

The base length, b = (√39)/3 units ≈ 2.08 units

4) The height of the hexagon, h = 2 × The length of the apothem, lₐ

The length, lₐ, of the apothem is given as follows;

l_a = \sqrt{\left (y_{2}-y_{1}  \right )^{2}+\left (x_{2}-x_{1}  \right )^{2}}

Given the apothem coordinates, (2, 3), and (3, 1.5), we have;

l_a = \sqrt{\left (3-1.5  \right )^{2}+\left (2-3  \right )^{2}} = \sqrt{1.5^2 + (-1)^2} =\sqrt{3.25}

The height of the hexagon, h = 2 × √3.25 units ≈ 3.61 units.

The formula for compound interest is:
sveta [45]

Answer:

Future value, A = $642

Step-by-step explanation:

Given the following data;

Principal = $500

Interest rate = 5% = 5/100 = 0.05

Time, t = 5 years

n = 365

To find the future value, we would use the compound interest formula;

A = P(1 + \frac{r}{n})^{nt}

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

A = 500(1 + \frac{0.05}{365})^{365*5}

A = 500(1 + 0.000137)^{1825}

A = 500(1.000137)^{1825}

A = 500*1.2840

Future value, A = $642
