Answer:
82
Step-by-step explanation:
The formula is:
(n*26) - 204
Equation is (n * a) + x
n = 10 => 10a + x = 56 => x = 56-10a
n = 12 => 12a + x = 108 => x = 108 - 12a
56-10a = 108-12a
2a = 52
a = 26
x = 56 - 10a = 56 - (10*26) = -204
Equation = (26 * n) - 204
n = 11 => (26 *11) - 204 = 286 - 204 = 82
The 11th term will be equal to 82
What is arithmetic progression?An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
The formula is:
Equation is (n * a) + x
(n*26) - 204
n = 10 => 10a + x = 56 => x = 56-10a
n = 12 => 12a + x = 108 => x = 108 - 12a
56-10a = 108-12a
2a = 52
a = 26
x = 56 - 10a = 56 - (10*26) = -204
Equation = (26 * n) - 204
n = 11 => (26 *11) - 204 = 286 - 204 = 82
Hence the 11th term will be equal to 82.

x = (4 - 3x)/k
solve for x
Answer:
x = 4/( k+3)
Step-by-step explanation:
x = (4 - 3x)/k
Multiply each side by k
xk = (4 - 3x)/k*k
xk = (4 - 3x)
Add 3x to each side
xk+3x = 4
Factor out x
x ( k+3) =4
Divide each side by (k+3)
x ( k+3) / ( k+3) =4/( k+3)
x = 4/( k+3)

Suppose thatb if a person travels the Europe for the first time, the probability that he will visit London is 0.70; Paris is 0.64; Rome is 0.58; Amsterdam is 0.58; London and Paris is 0.45; London and Rome is 0.42; London and Amsterdam is 0.41; Paris and Rome is 0.35; Paris and Amsterdam is 0.39; Rome and Amsterdam is 0.32; London, Paris and Rome is 0.23; London, Paris and Amsterdam is 0.26; London, Rome and Amsterdam is 0.21; Paris, Rome and Amsterdam is 0.20, and all 4 cities is 0.12. What is the probability that he will see at least one of these four cities?
Answer:
The probability that he will visit at least one of the four cities is 0.88
Step-by-step explanation:
The given information can be presented as follows;
The probability that he will visit London = 0.70 = A
The probability that he will visit Paris = 0.64 = B
The probability that he will visit Rome = 0.58 = C
The probability that he will visit Amsterdam = 0.58 = D
The probability that he will visit;
London and Paris = 0.45 = A∩B
London and Rome = 0.42 = A∩C
London and Amsterdam = 0.41 = A∩D
Paris and Rome = 0.35 = B∩C
Paris and Amsterdam = 0.26 = B∩D
London, Paris and Rome = 0.23 = A∩B∩C
London, Paris, and Amsterdam = 0.26 = A∩B∩D
London, Rome and Amsterdam = 0.21 = A∩C∩D
Paris, Rome and Amsterdam = 0.20 = B∩C∩D
All 4 cities = 0.12 = A∩B∩B∩D
Therefore, the probability, P(at least one), that he will visit at least one of the four cities is the complement of the probability that he will visit all the four cities
∴ P(at least one) = (A∩B∩B∩D)' = 1 - (A∩B∩B∩D) = 1 - 0.12 = 0.88
P(at least one) = 0.88
Which gives, the probability that he will visit at least one of the four cities = 0.88.

Answer:
Angle 1: 127
Angle 2: 153
Step-by-step explanation:
First, let's find angle 1 by finding the angle that's supplementary to it.
To solve for it, we can set up an equation where the unknown angle and the other angles in the triangle it's in add up to 180:
x+95+32=180
x=53
Since angle 1 is supplementary to 53, that means that angle 1 is equal to 180-53 = 127.
Then, to find angle 2, we can find the angle that's supplementary to it.
To solve for that, we can set up an equation where that unknown angle and the other angles in the triangle it's in add up to 180:
26+127+x = 180
x = 27
Since angle 2 is supplementary to 27, that means that angle 2 is equal to 180-27 = 153.

Answer:
3,000 is the numerical increase and 15% is the percentage increase.
Step-by-step explanation:
It's quite easy to see that 3,000 more people were added to 20,000, since 23,000 - 20,000 = 3,000. To find the percentage, simply take 20,000 and divide it by the additional increase number, which is in this case 3,000. 20,000/3,000 = 0.15. Converting decimals to percentages, we take the digits behind the decimal and add the percent sign since 100 is equal to 1 or the whole. So 0.15 = 15%, which is the percent increase.
Answer:
actual amount of increase is 3000
% increase is 15%
Step-by-step explanation:
The actual amount of increase is
23,000-20,000= 3,000
To find the percent increase, take the actual amount of increase and divide by the original amount
3,000/20000=.15
Change to percent
15%

What is the 7th term of the geometric sequence?
2, 8, 32, 128, ...
To find the 7th term of the geometric sequence 2, 8, 32, 128, ..., we must first determine the common ratio between consecutive terms.
The common ratio, denoted by 'r', is found by dividing any term by its preceding term. In this case, dividing 8 by 2 gives us a common ratio of 4. Now that we know the common ratio, we can use the formula for the nth term of a geometric sequence, which is given as: [tex]aₙ = a₁ * r^(n-1)[/tex]
Here, aₙ represents the nth term of the sequence (the term we are trying to find), a₁ is the first term (2 in this case), r is the common ratio (4 in this case), and n is the position of the term we are trying to find (7 in this case). Plugging in the given values, we get: a₇ [tex]= 2 * 4^(7-1) = 2 * 4^6 = 2 * 4 * 4 * 4 * 4 * 4 * 4 = 2 * 4,096 = 8,192[/tex]Therefore, the 7th term of the geometric sequence 2, 8, 32, 128, ... is 8,192.

On a scale drawing of Caleb's house, the four bedroom walls each measure 10 inches wide by 6 inches tall. The scale of the drawing is 1 inch = 1.5 feet. Caleb will paint all four walls. If a gallon of paint covers 250 square feet, how many gallons of paint will Caleb need?
Answer:
Approximately 2 gallons of paint are required to paint four bedroom walls
Step-by-step explanation:
Dimensions of the four bedroom walls = 10 inches wide by 6 inches tall
As 1 inch = 1.5 feet,
10 inches [tex]=10(1.5)=15[/tex] feets
6 inches [tex]=6(1.5)=9[/tex] feets
Dimensions of the four bedroom walls = 15 feets wide by 9 feets tall
Area of one wall = product of the dimensions [tex]=15(9)=135[/tex] square feets
Area of four walls = [tex]4(135)=540[/tex] square feets
Area of four walls covered by a gallon of paint = 250 square feets
So,
Amount of paint required = [tex]\frac{540}{250}=2.16[/tex]
That is approximately 2 gallons of paint are required to paint four bedroom walls
Alia and Huda share some sweets in the ratio 7:3. Alia gives 3 sweets to Huda and
now the ratio is 5:3. How many sweets did each have initially?
Answer:
Alia=28
Huda=12
Step-by-step explanation:
Let the constant of proportionality be x
Hence, no. of sweets Alia had initially = 7x
No. of sweets Huda had initially = 3x
No. of sweets Alia has now= 7x-3
No. of sweets Huda has now= 3x+3
We know that, the ratio of the no. of sweets Alia has now to no. of sweets Huda has now = 5:3
Hence,
[tex](7x-3) : (3x+3)=5:3\\By\ equalizing\ the\ ratios,\ we\ get,\\ 3(7x-3)=5(3x+3)\\21x-9=15x+15\\21x-15x=15+9\\6x=24\\x=4[/tex]
As we now got the constant of proportionality to be 4,
No. of sweets Alia had initially = 7*4=28
No. of sweets Huda had initially= 3*4=12
Given parameters:
Original ratio number of sweets of Alia to Huda = 7:3
Final ratio = 5:3
Alia gives 3 sweets
Huda receives 3 sweets
To solve this problem, we have to derive an algebraic equation.
Let us assume that the total number of sweets = x
So;
The ratio originally is;
7x : 3x
Alia has 7x sweets
Huda has 3x
Now Alia has (7x -3)sweets after giving out 3
Huda has (3x + 3)sweets after receiving 3
So;
7x -3 : 3x + 3 = 5 : 3
[tex]\frac{7x - 3}{3x + 3} = \frac{5}{3}[/tex]
3(7x -3) = 5(3x + 3)
21x - 9 = 15x + 15
21x -15x = 15 + 9
6x = 24
x = 4
Initially, Alia has 7x sweets = 7 x 4 = 28 sweets
Huda has 3x sweets = 3 x 4 = 12 sweets
Therefore, Alia has 28 sweets and Huda 12 sweets initially.
