Answer:

See the explanation below

Step-by-step explanation:

The question is asking what the income is and what the rest amount is

We are told that 75% of the income is Rs. 9000

Le the income be x

so

75/100*x=9000

0.75x=9000

x= 9000/0.75

x=12000

Hence the income is

Rs. 12000

The rest amount

=12000-9000

=Rs. 3000

Answer:

The written inequality can be written as 0.12x + 25 <= 150.

Step-by-step explanation:

To solve the inequality you would plug in the 125 miles for x so 0.12(125) + 25 <= 150 0.12(125) would equal 15 so 15 + 25 <= 150 150/40 would equal 3.75 days but you cant have .75 of a day so Violet would have three days max to afford to rent the car while staying in her budget.

A rental car company charges $25 per day to rent a car and $0.12 for every mile driven. The inequality can be written as 0.12x + 25 <= 150.

The set of values of the variable involved in the inequality for which the considered inequality holds true is called the solution set for that inequality.

A rental car company charges $25 per day to rent a car and $0.12 for every mile driven.

Violet wants to rent a car, knowing that:

She plans to drive 125 miles.

She has at most $150 to spend.

To solve the inequality in the 125 miles for x

So, 0.12(125) + 25 <= 150

= 0.12(125)

= 15

So, 15 + 25 <= 150

= 150/40

= 3.75 days

So, Violet would have three days max to afford to rent the car while staying within her budget.

Answer:

*Partially solved, cannot be fully solved, even in the most complex of mathematicians.

— Attempts at axiomatizing are useful even beyond mathematics: they help to clarify the basic assumptions and keep the mind in order. This is good and encouraging.

— This order may be much more complicated and counter-intuitive than the preceding chaos. This is not so encouraging, but not too bad: axiomatizing is a powerful tool, and its use requires accuracy.

— The road to rigour is infinite. This is neither encouraging nor discouraging: this is reality.

Step-by-step explanation:

‘One can say that, with the birth of quantum theory, Hilbert’s sixth problem was split into three different questions:

(i) Axiomatize classical probability.

(ii) Axiomatize the new (quantum) probability.

(iii) Clarify the connections between the two.’

The essence of the sixth problem as a programmatic call for the axiomatization of the physical sciences.

We can try to outline the possible ‘semantic of physical reality’ that complements semantics of physical theories, is simple, abstract and free from theoretical allusions. Let us just follow the machine learning abstractions. There are two alphabets: perceptions Inline Formula and actions Inline Formula.

The ‘person’ selects and sends ‘outwards’ the symbols from Inline Formula (actions) and receives symbols from Inline Formula (the answers to actions or just signals from ‘outside’).

There is the ‘freedom of will’: selection of a symbol from Inline Formula has no restrictions (Inline Formula models commands to actuators; the real actions and their results return to the person with the Inline Formula feedback).

10 problems, namely {3,7,10,11,13,14,17,19,20,21}, have a resolution that is accepted by a general consensus of the mathematical community. On the other hand, the solutions proposed for seven problems, namely {1,2,5,9,15,18,22}, are only partially accepted as resolving the corresponding problems.  

Therefore, my conclusion, is that my brain is fried, and this cannot be fully solved.

Answer:

[tex]P(x < 2.892) = 4.36\%[/tex]

Step-by-step explanation:

Given

[tex]N = 700[/tex] --- Population

[tex]\mu = 2.894[/tex] -- Mean

[tex]\sigma = 0.009[/tex] --- Standard deviation

[tex]n = 55[/tex] -- Sample

Required: [tex]P(x < 2.892)[/tex]

This question will be solved using the finite correction factor

First, calculated the z score

[tex]z = \frac{x - \mu}{\sqrt{\frac{N -n}{N -1}} * \frac{\sigma}{\sqrt n}}[/tex]

[tex]z = \frac{2.892 - 2.894}{\sqrt{\frac{700 -55}{700 -1}} * \frac{0.009}{\sqrt {55}}}[/tex]

[tex]z = \frac{-0.002}{\sqrt{\frac{645}{699}} * \frac{0.009}{7.42}}[/tex]

[tex]z = \frac{-0.002}{\sqrt{0.92} * \frac{0.009}{7.42}}[/tex]

[tex]z = \frac{-0.002}{0.95917 * 0.0012129}[/tex]

[tex]z = -1.71[/tex]

So:

[tex]P(x < 2.892) = P(z < -1.71)[/tex]

Using z table

[tex]P(x < 2.892) = 0.043633[/tex]

[tex]P(x < 2.892) = 4.36\%[/tex]

Step-by-step explanation:

Answer:

h = 3

Step-by-step explanation:

Looking at the given image, the height(h) divides the side length of 8 into two equal parts as we see that the height is perpendicular to the side length of 8 m.

Thus, looking at the half triangle of the face where the h is indicated, we can use pythagoras theorem to find h where the hypotenuse is 5 as shown in the diagram since each vertical cross section is an Isosceles triangle. Thus,

h² + (8/2)² = 5²

h² + 4² = 25

h² + 16 = 25

h² = 25 - 16

h² = 9

h = √9

h = 3

Answer:

" There are 23 people in the club."

Step-by-step explanation:

We want to know how many member's friends came to the meeting.

We know that:

There are 23 people in the club

5 members of the club, invited 2 friends each.

So we have 5 times 2 friends invited:

Then there are 5*2 = 10 people invited to the first meeting.

Notice that the fact that there are 23 people in the club is never used, them the information that is not necessary to solve this problem is " There are 23 people in the club."

Answer:

D. 21 1/2 feet

Step-by-step explanation:

The total length of fencing, in feet, that Bethany will need is 13 1/2 feet.

The total length of fencing needed can be determined by calculating the perimeter of the area. Perimeter is the distance round the area.

Perimeter of the area = 2(length + width)

2 (4 3/4 + 2)

2 x 6 3/4

2 x 27/4 = 13 1/2 feet.

17.50/5 = 3.50= 1 gallon

so you divide 49 by 3.5 and you get 14 and 14= 14 gallons
