Answer:

The mean is 47

Step-by-step explanation:

First, you want to add up all of the numbers.

47 + 25 + 43 + 33 = 148

Now, you want to divide what you got by how many numbers there are.

148/4 = 37

The mean is 47

   Mean of the terms given in the data set as {47, 25, 43, 33} (four terms) will be 37.

          Mean = [tex]\frac{\text{Total of the terms in a data set}}{\text{Numbers of the terms}}[/tex]

Total of the terms given in the the data set = 47 + 25 + 43 + 33

                                                                        = 148

Number of terms in the data set = 4

Substitute these values in the expression of the mean,

Mean = [tex]\frac{148}{4}[/tex]

          = 37

      Therefore, mean of the data set given in the question is 37.

8 feet squared

Step-by-step explanation:

The area of bedroom 1 is 2 length and 3 width. multiply them and you get 6ft^2 plus the 2 squares on the right.

The area of Bedroom 1 is,

⇒ 32 feet²

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

To find square feet of flooring are needed to cover the entire floor of Bedroom 1.

Here, We have;

1 in = 4 feet

Hence, Length of bedroom 1 = 8 feet

Width = 4 feet

Thus, The area of Bedroom 1 is,

⇒ 8 x 4 = 32 feet²

Hence, The area of Bedroom 1 is,

Answer:

The answer is two gallons per minute.

Step-by-step explanation:

The gallons are always double the minutes. This means that there are 2 gallons per minute.

Answer:

A.

Step-by-step explanation:

The Y-intercept is 3 so C and D are automatically are wrong because their Y intercept is 2.

The slope is 2x because you count the points that the line goes through.

For example: From (-1,1) count up and right until you get another point,

count using [tex]\frac{Rise}{Run}[/tex] the rise of this equation is 2 and the run is 1 so [tex]\frac{2}{1} = 2\\[/tex]

Rise = Vertical

Run = Horizontal

Because the slope is increasing the slope is positive meaning B is incorrect because it's slope is negative.

Hope this was clear and helped you out!

The equation that matches the graph is y = -2x + 3

A linear equation is in the form:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept

The line passes through the point (0, 3) and (-1.5, 0). Hence:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-3=\frac{0-3}{1.5-0} (x-0)\\\\y=-2x+3[/tex]

The equation that matches the graph is y = -2x + 3

Step-by-step explanation:

x = nickles

y = dimes

0.05x + 0.10y = 1.70

x + y = 21

y = 21 - x

0.05x + 0.10 (21 - x) = 1.70

0.05x - 0.10x + 2.10 = 1.70

-0.05x + 2.10 = 1.70

-0.05x = -0.40
