Answer:
where is the multiple choice
Step-by-step explanation:
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
16 and 12 because 16-12=4 and 16+12=28
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.
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:
The <em>displacement </em><u>between t= 0 and t = 1 second</u> is given by:
Hence:
Then:
The displacement is of 0 m.
