Answer: 50
Step-by-step explanation:
First let's set up an equation by calling the score he needs to get, x:
[tex]\frac{58 + 88 + 80 + 70 + x }{5}[/tex] = 75
58 + 88 + 80 + 70 + x = 75 x 5
296 + x = 375
x = 79
Karl scored 79 marks in 5th test.
What is Average?The ratio of the sum of the values in a particular set to all the values in the set is the mean value, which is the definition of the average.
Average = (Sum of values)/(Total number of values).
Given:
Karl earned scores of 58, 88, 80, and 70.
The average of 5 test = 75
let the marks scored in 5th test is x.
Then, (x+ 58 + 88 + 80 + 70)/ 5= 75
x+ 58 + 88 + 80 + 70 = 375
x + 296 = 375
x= 375- 296
x = 79
Hence, the marks on 5th test is 79.

In a sample of 700 gas stations, the mean price for regular gasoline at the pump was $2.894 per gallon and the standard deviation was $0.009 per gallon. A random sample of size 55 is drawn from this population. What is the probability that the mean price per gallon is less than $2.892?
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]

The radius of a circle is 10 meters. What is the angle measure of an arc 3 meters long?
{=37 m
=10 m
Give the exact answer in simplest form
Answer:
Ф = 0.3 radians
Step-by-step explanation:
The arc length formula is s = rФ. Solving for the angle measure Ф, we get:
Ф = s/r
and so with r = 10 m and s = 3 m, we get Ф = 3 m / 10 m = Ф = 0.3 radians

(a) axiomatic treatment of probability with limit theorems for foundation of statistical physics
(b) the rigorous theory of limiting processes "which lead from the atomistic view to the laws of motion of continua"
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.

Explain how to solve 5x^2-
3x = 25 by completing the square. What are the solutions?
what is the slope of the line?
Answer:
slope=7/4
Step-by-step explanation:
you can find the slope of the line from a graph using the formula rise/run, where rise is the change in y and run is the change in x
let's start with a clear point; for example, (-1,-3)
we need to go up, down, left, or right to get the rise/run
up/down is considered the rise
left/right is considered the run
if we go up or to the right, that's considered a positive move
if we go down or to the left, that's considered a negative move
we'll go from (-1,-3) to another clear point, like (3,4) for example
starting at (-1,-3):
go up 7, to the point (-1,4)
then move 4 to the right to get to the point (3,4)
we went up 7, so our rise is 7
we moved to the right 4, so that is our run
our slope then is 7/4
please see below for a graph if that would be helpful:

Mrs. Gurung spends 75% of her income every month which amounts to Rs 9000 and the rest she saves in a bank
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
Bethany is making a rectangular fenced-in area for her rabbit in her yard. The area measures 4 3 4 feet wide by 2 yards long. What is the total length of fencing, in feet, that Bethany will need? A. 6 3 4 feet B. 10 3 4 feet C. 13 1 2 feet D. 21 1 2 feet
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.
What is the total length of fencing needed?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.
Add the following lengths: 32'11"+11'3''
Answer:
44'2"
Step-by-step explanation:
32'11"+11'3' = 43'14" = 44'2"
Answer:
44'2"
Step-by-step explanation:
Starting with 32' 11", we'll add the 3" from the second number first. That will give us 32' + 14". Every 12" = 1 more foot, so that converts to 33' 2". Now add the 11' from the 11'3", and you have 44' 2". Does that make sense? Happy to answer any questions.

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."

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.
Write and solve an inequality which can be used to determine d, the number of days Violet can afford to rent while staying within her budget.
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.
What is the solution set for inequality?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.
