Answer: Tonya's calculation is incorrect because she mixed units of measurement. She used feet to measure one dimension of the room (10 feet) and inches to measure the other dimension (120 inches) and then calculated the area as 10 x 120 = 1200 square feet.

Area is a measure of the amount of space inside a two-dimensional shape, and it's typically measured in square units. To calculate the area of a rectangular room, you multiply the length of the room by the width of the room,

However in this case, Tonya used different units of measurement for length and width (feet and inches), and therefore the answer is incorrect.

You would need to convert inches to feet before multiplying 10 feet by 120 inches to get the area.

120 inches = 10 feet

So, the correct calculation of the area would be 10 feet * 10 feet = 100 square feet

It's worth mentioning that before calculating any area or volume, it's important to make sure that all units of measurement are consistent and the same.

The option that best describes X on the scatterplot is;

C: Outlier

Let us first define the terms in the given options before we analyze the scatterplot.

1) Negative correlation is defined as a relationship between two variables whereby one variable increases while the other decreases, and vice versa.

2) A nonlinear relationship is also referred to as nonlinear association, and it exists when a constant change in the independent variable does not result in a constant change in the dependent variable.

3) An outlier is defined as a data point that differs significantly from other observations.

4) Clusters are small populations that a wider population is divided into.

Now, from the scatter plot, we see that X is isolated from the plotted points which tells us that it differs greatly from the other points and as such it fits the definition of an outlier.

Answer:

124 units squared

Step-by-step explanation:

A(parallelogram) = 8 x 10 = 80

A(semicircle) = πr²/2

however, we need to use the Pythagorean Theorem to find 'r'

r² + 6² = 8²

r² = 84-36

r² = 28

r = [tex]\sqrt{28}[/tex] = [tex]\sqrt{4}[/tex]·[tex]\sqrt{7}[/tex] or 2[tex]\sqrt{7}[/tex]

A = π(2√7)² / 2

A = 4·7π / 2

A = 14π which is approx 44

Total Area = 44 + 80 = 124

Function: A function is a mathematical relationship between two sets of values, where each element in the first set (called the domain) is related to exactly one element in the second set (called the range). A function can be represented by a formula, equation, or graph, and it describes how one set of values is related to another.

Domain: In a function, the domain is the set of all possible values that can be used as input for the function. It is the set of values that the function operates on.

Range: In a function, the range is the set of all possible values that can be produced as output by the function. It is the set of values that the function produces as a result of operating on the domain.

Vertical line test: The vertical line test is a method used to determine whether a graph represents a function.

Step-by-step explanation:

Surface area of triangular prism = bh + (s1 + s2 + s3)*L

Where,

b = 4.5 in.

h = 6 in.

s1 = 7.5 in.

s2 = 4.5 in.

s3 = 6 in.

L = 11 in.

Plug in the values

Surface area = 4.5*6 + (7.5 + 4.5 + 6)*11

Surface area = 27 + 198 = 225 in.²

Step-by-step explanation:

y = 3 is a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 3

x + y = 4 ← is the equation of a straight line

find the x and y- intercepts

to find the y- intercept let x = 0 in the equation and solve for y

0 + y = 4 , that is

y = 4 ⇒ (0, 4 ) is a point on line

to find the x- intercept let y = 0 in the equation and solve for x

x + 0 = 4 , that is

x = 4 ⇒ (4, 0 ) is a point on the line

the graph representing the system is

a horizontal line y = 3 and another line passing through (0, 4 ) and (4, 0 )

Answer:

1.425

Step-by-step explanation:

when 1pound is 0.95

then 1.5should be multiplied by 0.95

An equation is y = -4x/3 + 10.

A graph of the equation is shown in the image attached below.

In order to write and graphically solve an equation that model this situation, we would assign variables to the number of pound of peaches and number of pounds of apples respectively, and then translate the word problem into algebraic equation as follows:

Next, we would translate the word problem into an algebraic equation as follows;

$2/pound × Pounds of peaches = 2x.

$1.50/pound × pounds of apples = 1.50y

Combining the two expressions above, we have the following:

2x + 1.50y = 15

Making y the subject of formula, we have:

1.50y = 15 - 2x

y = (15 - 2x)/1.50

y = -4x/3 + 10

Therefore, an equation in slope-intercept form that relates the variables is y = -4x/3 + 10.

The definition of a congruent polygon is a polygon that is the same shape, has the same length of sides, and has the same interior angles as the polygon it is being compared to. Congruent shapes must all be the same type of shape in order to fulfill the requirement.

Given that, ABCD≅EFGH

We know that, corresponding parts of congruent polygon are equal.

Now, (4y-4)°=28°

4y=32

y=8

10x=200

x=20

Therefore, the value of x is 20 and the value of y is 8 from the given quadrilaterals.

Therefore , the solution to the given problem of interest comes out to be $272.

Simple interest is calculated by dividing initial capital by the interest rate, the duration, and other variables. The formula employed in marketing is simple return = principle + interest plus hours. This approach is the simplest way to calculate interest. Calculating interest as a percentage of the principle sum is the most common approach. For instance, he may only pay his portion of the interest if he borrowed $100 from a friend and agreed to pay it back with 5% interest. $100 (0.05) = $5. You should pay interest when you make loans, and you also must pay interest when you lend it. Usually, interest is calculated as a portion of a loan.

Here,

Given: $250 in principal

a 2.2% interest rate

and a 4-year term

To discover the basic interest:

Using this formula

Simple interest is equal to

=>P*R*T/100,

=> 250*2.2*4/100

=> 22.

Total amount after 4 years = 250 + 22 =272

Therefore , the solution to the given problem of simple interest comes out to be $272.
