A foresting service conducted a survey to see if tree farms that planted hardwood trees were more profitable over a 30-year peri

Advocard [28]

Answer:

The results are statistically significant because planting hardwood trees have a higher profit per acre.

Step-by-step explanation:

From the question above,

It shows that hardwood trees had a 46% higher Profit per acre than softwood trees.

Meaning that for every $100 made on softwood trees, $146 profit would be made on hardwood trees i(including both primary and secondary expenses; making the hardwood trees more profitable.

The information given is enough to reach a conclusion that planting hardwood trees have a higher profit per acre than softwood trees.

A two-factor research study has 2 levels of factor A and 3 levels of factor B with a separate sample of n = 5 subjects in each t

amid [387]

Answer:

option (b) df = 1, 24

Step-by-step explanation:

Data provided in the question:

levels of factor A, a = 2

levels of factor B, b = 3

Subjects in each Sample, s = 5

n = 5 × 3 × 2 = 30

Now

df for Factor A = a - 1

= 2 - 1

= 1

df for Factor B = b - 1

= 3 - 1

= 2

df for Interaction AB = ( a - 1 ) × ( b - 1 )

= 1 × 2

= 2

df for Total = n - 1

= 30 - 1

= 29

df for error = 29 - 5

= 24

Hence,

df values for the F-ratio evaluating the main effect of factor A is 1, 24

The correct answer is option (b) df = 1, 24

Tate fills a container with 9 1/2 cups of lemonade. Tate drinks 32 fl. oz. of lemonade. How many fluid ounces are left?

iren [92.7K]

Answer:

<u>44 fluid ounces</u> of lemonade are left.

Step-by-step explanation:

Given:

Tate fills a container with 9 1/2 cups of lemonade.

Tate drinks 32 fl. oz. of lemonade.

Now, to find the quantity of fluid ounces left.

So, we convert the unit of cups into fluid ounces.

Tate fill the container of lemonade with = $9\frac{1}{2}\ cups.$

As, 1 cup = 8 fluid ounces.

So, by conversion factor:

$9\frac{1}{2} \times 8$

$=\frac{19}{2} \times 8$

$=9.5\times 8=76\ fl.\ oz.$

<em>Thus, Tate fill the container of lemonade with = 76 fl. oz.</em>

<em>Tate drinks lemonade = 32 fl. oz.</em>

Now, to get the fluid ounces left we subtract the quantity of lemonade Tate drink from the total quantity of lemonade filled in the container:

$76-32$

$=44\ fl.\ oz.$

Therefore, 44 fluid ounces of lemonade are left.

Finding the Area of a Trapezoid in the Coordinate Plane

Oksanka [162]

The area of the trapezoid is 118 squre units

<h3>Area of a trapezoid</h3>

The formula for calculating the area of a trapezoid is expressed as:

A = 0.5(a+b)h
a = AD = √20
b = BC = √80
height = h = √40

Substitute into the formula

A = 0.5(√1600)*√40

A = 0.5 * 40 * √40

A = 20√40

A = 118 squre units

Hence the area of the trapezoid is 118 squre units
