Mathematics
1 answer:
Korolek [52]2 years ago
7 0

Answer:

Step-by-step explanation:

Assuming the order in which he answers the questions matter the answer is the number of permutations of 8 in 10.

This is 10! / (10-8)!

= 1,814.400.

If the order does not matter then the answer is the number of combinations of 8 from 10:

This is 10!/8!*2!

= 45.

(a.)

Mean= sum / n

Mean= (123+116+122+110+175+126+125+111+118+117) / 10

Mean=1243 / 10

Mean= 124.3

Median:

Rearranged the data in order first

110,111,116,117,118,122,123,125,126,175

118 and 122 are at the middle

Median=1/2(n1 + n2)

Median=1/2(118+122)

Median=240/2

Median= 120

(b) 175 is the larger than the others value and larger than the mean, so it is the substantial difference between the mean and the highest value (175).

How to make 3 dimensional object become 4 dimensional object
NISA [10]

Using Hinton's method;

  • Draw two ordinary 3D cubes in 2D space, one encompassing the other, separated by an "unseen" distance
  • Then draw lines between their equivalent vertices.
  • The eight lines connecting the vertices of the two cubes in this case represent a single direction in the "unseen" fourth dimension.

<h3>What is a 4 dimensional shape?</h3>

A four-dimensional shape (4D) is a mathematical extension of a three-dimensional or 3D space.

Three-dimensional space is the simplest possible abstraction of the observation that one only needs three numbers, called dimensions, to describe the sizes or locations of objects.

Using Hinton's method;

  • Draw two ordinary 3D cubes in 2D space, one encompassing the other, separated by an "unseen" distance
  • Then draw lines between their equivalent vertices.
