Answer:

The mean absolute deviation = 3.5°F

Step-by-step explanation:

The sum of the given temperatures, ∑T, is found as follows;

∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F

The number of days, n, over which the temperature was tracked = 8 days

Therefore, the mean, [tex]\bar x[/tex], of the data set = ∑T/n = 480°F/8 = 60°F

The mean absolute deviation is given by the following formula;

[tex]Mean \ absolute \ deviation = \frac{\sum \limits_{i = 1}^{n} \left | x_i - \bar x \right | }{n}[/tex]

Therefore, we have;

66 - 60 = [tex]\left | 6\right |[/tex] = 6

57 - 60 = [tex]\left | -3\right |[/tex] = 3

61 - 60 =  [tex]\left | 1\right |[/tex] = 1

65 - 60 =  [tex]\left | 5\right |[/tex] = 5

54 - 60 =  [tex]\left | -6\right |[/tex] = 6

62 - 60 =  [tex]\left | 2\right |[/tex] = 2

59 - 60 =  [tex]\left | -1\right |[/tex] = 1

56 - 60 =  [tex]\left | -4\right |[/tex] = 4

The mean absolute deviation is therefore;

The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.

Answer:

[tex](x,y)\rightarrow(x-1,y+2)[/tex]

Step-by-step explanation:

One unit left would be subtracting 1 from the pre-image's x-value.

Two units up would be adding 2 to the pre-image's y-value.

The translation rule would be:

[tex](x-1,y+2)[/tex]

Hope this helps.

The coordinates after the translation of 1 unit left and 2 units up will be (x-1,y+2).

It is described as the alteration of the geometric body's form and coordinates. It is also known as a two-dimensional transformation. Rotation, translation, reflection, and gliding translation are just a few of the geometric transformations that may affect geometry.

It is given that the coordinates of the points are (x,y)

We have to find the coordinates after the translation of 1 unit left and 2 units up.

A sort of transformation called a translation involves moving each point in a figure the same distance in the same direction.

The final unit would be to deduct 1 from the x-value of the pre-image. The pre-y-value images would be increased by 2 by moving two units higher.

Thus, the obtained coordinates will be (x-1,y+2).

The question is incomplete.

The complete question is" if the coordinates of the points are (x,y). What will be the coordinates after the translation of 1 unit left and 2 units up?

Step-by-step explanation:

The graph starts when the value of x is -1 and ends when it's value is 5 , So domain is [-1,5]

The highest value of the graph is 4 which is at x = -1 and the lowest value of the graph is 0 , which is at x = 5, So range is [0,4]

The domain is equal to all the input values (x-values)

The range is equal to all the output values (y-values)

In this problem,

The domain: [-1, 5]

The range: [0, 4]

A signed number to represent a given population change is -43,000.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

Since the population of a certain city decreased by 43,000 people.

The negative sign indicates that the population decreased, which means there was a decrease in the quantity of 43,000 people.

Thus, we can population change is shown by -43,000.

Hence, a signed number to represent this population change is -43,000.

Answer: 107

Step-by-step explanation:

102.3 can be rounded down to 102 (because the 3 at the end of the number is  less than 5)

4.7 can be rounded up to 5 (because the 7 at the end of the number is greater than 5).

102.3  → estimate = 102

    4.7 →  estimate =   5  

   estimated sum  = 107

Note that estimating the sum is NOT the same as simply adding the numbers and then rounding the sum.

Answer:

The number is 888888

Step-by-step explanation:

Here, we are interested in knowing the six digit number thought of by No time.

The clue we have here is that the six digit number has same value of digit for all its constituent.

Thus, if the digit in the thousands place is 8,000, then it actually means that it carries a value of 8 and thus, all the digits in the number is 8 alone.

So the 6 digit number is 888888

Answer:

The values of x and y are;

x = 7 and y = 4.5

Step-by-step explanation:

The question is a word problem, given that the shape of the kite Karl makes is a parallelogram

The coordinates of the vertices are;

D(3, 6), G(1, 3), H(4, y), and E(x, 6)

From the properties of a parallelogram we have;

The diagonals bisect each other

Therefore;

GH = EH = 1/2·GE

Therefore, we have;

The coordinates of the point H = The coordinate of the midpoint of the line EG

The coordinates of the midpoint of a line with end points, (x₁, y₁) and (x₂, y₂) is given as follows;

The coordinates of the midpoint of a line = ((x₁ + x₂)/2, (y₁ + y₂)/2)

Therefore;

The coordinates of the midpoint of the line EG  are ((1 + x)/2, (3 + 6)/2)

Given that the midpoint of EG is the point H and the coordinate of the point H is (4, y), we have;

(1 + x)/2 = 4, therefore;

2 × 4 = 1 + x

8 = 1 + x

x = 8 - 1 = 7

Similarly, we have from the coordinate of point H which is given as follows;

((1 + x)/2, (3 + 6)/2) = (4, y)

y = (3 + 6)/2 = 9/2 = 4.5

Therefore, x = 7, y = 4.5.

Parallel sides of a parallelogram have the same slope

The values of x and y are 6 and 3, respectively.

The coordinate points are given as:

[tex]\mathbf{D =(3,6)}[/tex]

[tex]\mathbf{G =(1,3)}[/tex]

[tex]\mathbf{H =(4,y)}[/tex]

[tex]\mathbf{E =(x,6)}[/tex]

Lines DG and HE are parallel.

This means that they have the same slope (m)

The slope is calculated as:

[tex]\mathbf{m = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]

So, we have:

[tex]\mathbf{m_{DG} = \frac{3 - 6}{1 - 3}}[/tex]

[tex]\mathbf{m_{DG} = \frac{- 3}{- 2}}[/tex]

[tex]\mathbf{m_{DG} = \frac{3}{2}}[/tex]

Similarly

[tex]\mathbf{m_{HE} = \frac{6 - y}{x - 4}}[/tex]

The slopes are equal.

So, we have:

[tex]\mathbf{\frac{6 - y}{x - 4} = \frac 32}[/tex]

By comparison:

[tex]\mathbf{6 - y = 3}[/tex] and [tex]\mathbf{x - 4 = 2}[/tex]

Solve for y in [tex]\mathbf{6 - y = 3}[/tex]

[tex]\mathbf{y = 3}[/tex]

Solve for x in [tex]\mathbf{x - 4 = 2}[/tex]

[tex]\mathbf{x = 6}[/tex]

Hence, the values of x and y are 6 and 3, respectively.
