4. The mean of the distribution of compy heights is 33.5 cm, and the standard deviation is 2.56 cm. Interpret the mean and stand
alina1380 [7]

Answer:

a) The average of compy heights is 33.5 cm

b) The 68.3 % of all compy heights are in the interval:

   (30.94,36.06)

Step-by-step explanation:

a) Meaning of the mean

The mean is a number expressing the central or typical value in a set of data.

The average of compy heights is 33.5 cm. If the select one height randomly its height will be in average 33.5 cm

b) Meaning of standard deviation

The standard deviation is a quantity expressing by how much the members of a group differ from the mean value for the group.

The 68.3 % of all compy heights are in the interval

(33.5cm - 2.56cm, 33.5cm + 2.56cm) = (30.94,36.06)

It means that the 68.3 % of all data is in the interval:

(μ - δ, μ +δ)

Where: μ is the mean

            δ is the standard deviation

Which figure represents the image of parallelogram LMNP after a reflection across the line y = x?
Taya2010 [7]
When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. This gives you such reflection rule:

From the diagram:
L(3,1), M(4,3), N(5,3) and P(4,1).
Using the reflection rule, you can find coordinates of image points:
L'(1,3), M'(3,4), N'(3,5) and P'(1,4).
As you can see, these are coordinates of vertices of the figure C.
Answer: correct choice is option 3 - figure C.

An object oscillates as it moves along the
Sauron [17]

Using it's formula, it is found that the displacement between t= 0  and t = 1 second is of 0 m.

The equation of motion is given by:

x(t) = 4\sin{\left(\pi t + \frac{\pi}{6}\right)}

The <em>displacement </em><u>between t= 0  and t = 1 second</u> is given by:

d = x(1) - x(0)

Hence:

x(1) = 4\sin{\left(\pi + \frac{\pi}{6}\right)} = 4\sin{\left(\frac{7\pi}{6}\right)} = -\frac{4}{2} = -2

x(0) = 4\sin{\left(\frac{\pi}{6}\right)} = \frac{4}{2} = 2

Then:

d = x(1) - x(0) = -2 + 2 = 0

The displacement is of 0 m.
