Mathematics
1 answer:
11Alexandr11 [23.1K]3 years ago
4 0

Answer:

E. 72.7

Step-by-step explanation:

Here, we need to figure out the proportion of the population, which is higher than 20.  

Now, in this statement, the data set of the population is explicitly given, so the sample is irrelevant.

Here, the set of data is :  5, 33, 25, 55, 96, 75, 23, 69, 37, 17, 12.

Among this given data set of 11, The numbers which are higher than 20 are {33, 25, 55, 96, 75, 23, 69, 37}.

So, here 8 numbers are present in this data set which are greater than 20.

So for finding out the proportion, the calculation will be:

Calculation:

\frac{8}{11} * 100 = 72.72%

Therefore we get from the calculation that the population proportion, which is higher than the number 20, is 72.72% or 72.7%.

The perimeter of a rectangle is 128 cm, and the ratio of its sides is 5: 3. Find the area of ​​a rectangle
Juliette [100K]

Answer:

Area = 960 cm^2

Step-by-step explanation:

Perimeter (P) = 2 (l + w)

P = 2l + 2w

Let the length be 5x

Let the width be 3x

From the question, P = 128.

Therefore:

128 = 2l + 2w

Divide both sides by 2.

l + w = 64

Recall we said:

l = 5x

w = 3x

So then:

5x + 3x = 64

8x = 64

Divide both sides by 8

x = 64/8

x = 8.

Since x = 8

Length = 5x = 5*8 = 40cm

Width =3x = 3 * 8 = 24cm

Area of a RECTANGLE:

Area = length * width

Area = 40 * 24

Area = 960 cm^2

Show that the relation R consisting of all pairs(x, y)such that x and y are bit strings of length three or more that agree in th
Mice21 [21]

Answer:

See proof below

Step-by-step explanation:

An equivalence relation R satisfies

  • Reflexivity: for all x on the underlying set in which R is defined, (x,x)∈R, or xRx.
  • Symmetry: For all x,y, if xRy then yRx.
  • Transitivity: For all x,y,z, If xRy and yRz then xRz.

Let's check these properties: Let x,y,z be bit strings of length three or more

The first 3 bits of x are, of course, the same 3 bits of x, hence xRx.

If xRy, then then the 1st, 2nd and 3rd bits of x are the 1st, 2nd and 3rd bits of y respectively. Then y agrees with x on its first third bits (by symmetry of equality), hence yRx.

If xRy and yRz, x agrees with y on its first 3 bits and y agrees with z in its first 3 bits. Therefore x agrees with z in its first 3 bits (by transitivity of equality), hence xRz.
