Answer:

\implies \text{Required Number = }-40\tfrac{1}{4}

Step-by-step explanation:

\text{Part of the thread which is being cut from a spool = }5\tfrac{3}{4}\\\\=\frac{23}{4}

Number of students in the school project = 7

So, total part which is cut from the thread on the spool = Number of students × Part of the thread cut by one student

\text{Total part = }7\times \frac{23}{4}\\\\=\frac{161}{4}\\\\=40\tfrac{1}{4}

But, we are asked to tell a number which represents the change in the amount of the thread on the spool.

⇒ Required Number = Inverse of the total part which is cut

\implies \text{Required Number = }-40\tfrac{1}{4}

The following table represents the running times of the men's 100 meters final at the London Olympics.
Rom4ik [11]
This cannot be fit into a normal distribution. While the first 7 runners all have times relatively close, the time of the last runner is an outlier, as it is too far from the other data points. The standard deviation is calculated by taking the mean, subtracting each value from the mean, squaring the deviations, adding these, then dividing by the number of data points (7), and taking the square root. This gives an answer of SD = 0.1107.

The Midpoint of AB dkdldl
Nutka1998 [239]
  • The Midpoint of AB is (1,0).

Given that:

  • In line AB, where the coordinates of A is (3,1) and coordinates of B is (-1,-1).

To find:

  • The Midpoint of line AB.

So, according the question

We know that,

The midpoint M of a line segment AB with endpoints A (x₁, y₁) and B (x₂, y₂) has the coordinates M ( \frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2} ).

Now from question,

We know that the the coordinates of A is (3,1) and coordinates of B is (-1,-1) of line AB.

So, we can say that

   A is (3,1) or x₁ = 3 and y₁ = 1.

   B (-1,-1) or x₂ = -1 and y₂ = -1.

∵ The coordinates of midpoint M (X,Y)

          X = \frac{x_1 + x_2}{2}

              = \frac{3-1}{2}

              = 2/2

          X = 1.

And

          Y = \frac{y_1 + y_2}{2}

              = \frac{1-1}{2}

              = 0/2

          Y = 0.

So, the midpoint of line AB is M (1,0)
