Because the p-value is less than 0.05, the mean fitness scores for the two groups of students are significantly different

========================================================

Explanation:

Use a T calculator to find that P(T > 2.63) = 0.00459 approximately when we have 209 degrees of freedom.

Double this to get 2*0.00459 = 0.00918 and this is the approximate p-value

Since the p-value is less than alpha = 0.05, this means we reject the null and conclude that the two population means are significantly different.

The [OH] of vinegar to the  nearest hundredth is 2.82 * 10^-5

The sum of the pH and pOH of a substance is 14. Mathematically

[OH−] = Antilog (pOH)

Given the following parameters

[OH−] = Antilog (9.45)

Substitute

[OH−] = 2.82 * 10^-5

Hence the [OH] of vinegar to the  nearest hundredth is 2.82 * 10^-5

The value of a for the inverse function is 2, the value of b for the inverse function is 1, and the value of c for the inverse function is 0.25.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The inverse of the logarithmic function [tex]f(x) = \log_{0.5} x[/tex] is [tex]f^{-1}(x) = 0.5^x[/tex]

For x = −1 in the inverse function, then the value of a will be

[tex]f^{-1}(x) = 0.5^{-1}\\\\f^{-1}(x) = 2[/tex]

The value of a is 2.

For x = 0 in the inverse function, then the value of b will be

[tex]f^{-1}(x) = 0.5^{0}\\\\f^{-1}(x) =1[/tex]

The value of b is 1.

For x = 2 in the inverse function, then the value of c will be

[tex]f^{-1}(x) = 0.5^{2}\\\\f^{-1}(x) = 0.25[/tex]

The value of c is 2.

Answer:

A) 187.2

Step-by-step explanation:

Area of a regular polygon = 1/2(apothem × perimeter)

The perimeter of the triangle can me calculated by multiplying the side length by 3 ( because the polygon shown has 3 sides )

Side length = 20.8 , so perimeter = 3 × 20.8 = 62.4

Now we can find the area

Remember area of a regular polygon = 1/2(apothem × perimeter)

Apothem = 6 and perimeter = 62.4

So area = 1/2(6×62.4)

==> multiply 6 and 62.4

area = 1/2(374.4)

==> multiply 374 and 1/2

area = 187.2

Answer:

A rational number: 5.4, which also can be written as 27/5

Irrational number:

sqroot 28

approx= 5.29

Step-by-step explanation:

5.4 is a rational number because it is a terminating decimal. That means it ends after the 4, there are no more numbers. Also it can be written as a ratio (looks like a fraction) 27/5.

Sqroot28 is irrational. Since 28 is not a perfect square, when you squareroot it you get a number with a neverending decimal

sqroot28 = 5.2915026221...

since the decimal does not repeat or end it cannot be written as a ratio, so it is not rational

sqroot28 ~= 5.29

The system of equations of the number of bottles in both classes has two distinct equations

Mr. Sanchez's class sold 39 bottles, while Mr. Kelly's class sold 44 bottles

The given parameters are:

Mr. Sanchez = $1.73

Mr. Kelly = $1.44

Represent the number of bottles in both classes with x and y,

So, we have the following equations

1.73x + 1.44y = 130.83

x + y = 83

Next, we plot the graphs of the equations

From the graph (see attachment), we have:

(x,y) = (39,44)

Hence, Mr. Sanchez's class sold 39 bottles, while Mr. Kelly's class sold 44 bottles

The correct function for the given data representation will be,

y = 8x² + 10

What is Function?

A relation between a set of inputs having one output each is called a function.

Data representation is given by the scatterplot in the graph.

Now,

Take a function y = 8x² + 10

Then, Check each point on the x - axis for the value of y - axis.

So. Substitute x = 1 in the function we get;

y = 8 × 1 + 10

y = 8 + 10

y = 18

So, Point is (1, 18)

For, x = 3

y = 8 × 3² + 10

y = 72 +10

y = 82

So, Point is (3, 82)

For, x = 5

y = 8 × 5² + 20

y = 200 + 20

y = 220

So, Point is (5, 220)

Thus, All points are satisfy the given scatterplot graph.

So, The correct function for the given data representation will be,

y = 8x² + 10

The scale factor of the triangle ΔABC to ΔDEF will be 1/2. Then the correct option is A.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

The triangle ΔABC is similar to the triangle ΔDEF. Then the ratio of the corresponding sides will be constant. Then the scale factor is calculated as,

SF = 10 / 20

SF = 1 / 2

The scale factor of the triangle ΔABC to ΔDEF will be 1/2. Then the correct option is A.

Answer:

the answer is 202 square inch

Step-by-step explanation:

Ref. to the diagram I have attached.

First, we can find the area of the square.

Here the side of the square is given 4 inches.

1. So Area of the square= side * side= 4*4= 16 square inches.

Now let's find the area of the smaller rectangle. Now here,

As one side of the square is the same as the breadth of the rectangle, the breadth of the rectangle will be 4 inches, and the length is given 9 inches.

2. So, Area of the smaller rectangle= length* breadth= 9*4= 36 square inches.

Now, lastly, we will find the area of the bigger rectangle:

Here, the length will be 15 inches and the breadth will be 10 inches (as the opposite sides in a rectangle are equal and the values are already given).

3. ∴  Area of bigger rectangle= l*b= 15*10= 150 square inches.

So now,

To find the total area of the figure, we need to add all the areas:

36+ 16+ 150= 202 square in.

ANSWER IS 202 sq. in.
