There are 9 tables with 4 chairs in the restaurant.
Let's establish the variables:
Let x be the number of tables with 4 chairs
Let y be the number of tables with 5 chairs
Let z be the number of tables with 6 chairs
We know that there are a total of 19 tables, therefore:
x + y + z = 19 (equation 1)
We also know that the total number of people that can be accommodated in tables with 4 or 5 chairs is 64, therefore:
4x + 5y = 64 (equation 2)
We want to find the value of x, so we need to eliminate y from the equations above. We can do this by multiplying equation 2 by 4, and then subtracting it from equation 1:
x + y + z - 16x - 20y = 19 - 256
Simplifying:
-15x - 19y = -237
Dividing both sides by -19:
x = 9
Therefore, there are 9 tables with 4 chairs.

Polly bought 50 necklaces for £5 each. She sold all the necklaces and made a 70% profit on the original cost. Polly sold 40% of the necklaces for £11 each. 1 She then reduced the price and sold 3 of the remaining necklaces for £8 each. She sold all the remaining necklaces for the same price. Work out this price.
If Polly reduced the price and sold 3 of the remaining necklaces for £8 each, she sold the remaining necklaces for £6.70 each.
First, let's find the original cost of the necklaces:
50 necklaces * £5 = £250
Now, let's calculate the profit Polly made:
£250 * 70% = £175
So, the total amount she made from selling the necklaces is:
£250 + £175 = £425
Polly sold 40% of the necklaces for £11 each:
50 necklaces * 40% = 20 necklaces
20 necklaces * £11 = £220
She sold 3 necklaces for £8 each:
3 necklaces * £8 = £24
Now let's find the amount left after selling these necklaces:
£425 - £220 - £24 = £181
Polly has 50 - 20 - 3 = 27 necklaces remaining. Let's find the price at which she sold each of the remaining necklaces:
£181 / 27 = £6.70
So, Polly sold the remaining necklaces for £6.70 each.

In a recent BMO survey, many Canadian university students said they expected to owe
$26, 500 after graduation. A group of n = 64 university students are randomly selected, and
the average student loan debt is found to be $26,000 with a standard deviation of 500.
(a) Construct a 98% confidence interval for the true average student loan debt for
university students in Canada.
(b) Does this contradict the reported average of $26,500? Explain
(a) With 98% confidence, the true average student loan debt for university students in Canada falls between $25,883.5 and $26,116.5.
(b) No, this does not contradict the reported average of $26,500.
(a) To construct a 98% confidence interval, we can use the formula:
CI = [tex]\bar{x}[/tex] ± z* (σ/√n)
where [tex]\bar{x}[/tex] is the sample mean, σ is the population standard deviation (unknown), n is the sample size, and z* is the z-value from the standard normal distribution that corresponds to the desired level of confidence (98% in this case).
Substituting the given values, we get:
CI = 26,000 ± 2.33 * (500/√64)
CI = 26,000 ± 116.5
CI = (25,883.5, 26,116.5)
Therefore, we can say with 98% confidence that the true average student loan debt for university students in Canada falls between $25,883.5 and $26,116.5.
(b) No, this does not contradict the reported average of $26,500. The reported average is within the confidence interval we calculated, which means that it is a plausible value for the true average. The sample mean of $26,000 is slightly lower than the reported average, but this could be due to random sampling error.
Overall, we cannot make a definitive conclusion about the true average based on this sample alone, but we can say with 98% confidence that it falls within the range of $25,883.5 to $26,116.5.

The amount of time spent practicing shooting free throws and the percentage made in a game
The relationship between the amount of time spent practicing shooting free throws and the percentage made in a game can be described as a positive correlation.
As a basketball player dedicates more time to practicing free throws, their skill and accuracy in making these shots during a game typically improve.
Consistent practice is crucial for developing muscle memory and fine-tuning shooting techniques, which contribute to a higher success rate in making free throws during games. This increased success rate is reflected in the percentage of free throws made in a game, an essential factor that can influence the outcome of the match.
However, it is important to note that the correlation is not always linear. For example, a player who practices for hours on end may experience diminishing returns due to fatigue or lack of focus. Additionally, other factors such as pressure, game context, and individual differences in learning abilities can affect the percentage of free throws made in a game.
In conclusion, investing time in practicing free throws generally leads to an improvement in a player's in-game performance. While there are external factors that may influence the success rate, the positive correlation between practice time and the percentage of free throws made in a game emphasizes the importance of consistent and focused training for basketball players.

The circumference of the cake board is 35π cm.
The diameter of the round cake is 30 cm, which means its radius is 15 cm. The diameter of the circular cake board is 5 cm longer than that of the cake, which means its diameter is 30 + 5 = 35 cm. Therefore, the radius of the cake board is 17.5 cm.
The circumference of a circle is given by the formula:
[tex]$$C = 2 \pi r$$[/tex]
where [tex]$r$[/tex] is the radius of the circle. Using this formula, we can find the circumference of the cake board:
[tex]$$C = 2 \pi \cdot 17.5 = 35 \pi$$[/tex]
Therefore, the circumference of the cake board is 35π cm.
In other words, if you were to wrap a string or ribbon around the edge of the cake board, it would need to be 35π cm long.
This is an important measurement to consider when decorating or transporting a cake, as it can help ensure that the cake is centered on the board and that there is enough room for any additional decorations or trimmings.
In summary, the circumference of the cake board is 35π cm.

(1 point) Consider the power series (-1)"x" Vn +5 Find the radius of convergence R. If it is infinite, type "infinity" or "inf". Answer: R= What is the interval of convergence? Answer (in interval not
R= 1 and the interval of convergence is (-1, 1].
To find the radius of convergence, we can use the ratio test:
lim n→∞ |(-1)^n x^(n+1) Vn+5| / |(-1)^n x^n Vn+5| = lim n→∞ |x|
This limit exists for all x, and it equals 1 when |x| = 1. Therefore, the radius of convergence is R = 1.
To determine the interval of convergence, we need to check the endpoints x = -1 and x = 1 separately.
When x = -1, the series becomes:
∑ (-1)^n (Vn+5)
This is an alternating series with decreasing terms, so it converges by the alternating series test.
When x = 1, the series becomes:
∑ (-1)^n (Vn+5)
This is again an alternating series with decreasing terms, so it also converges by the alternating series test.
Therefore, the interval of convergence is (-1, 1].

In 2000, 1500 rabbits live in a warren in a certain area. the number of rabbits increases exponentially at a discrete rate of 7% per year. predict population in 2008&2022
The predicted populations of rabbits in the warren in 2008 and 2022 are 2909 and 9933, respectively.
To predict the population of rabbits in the warren in 2008 and 2022, we can use the formula for exponential growth:
P(t) = P₀ (1 + r)ᵗ
Where P(t) is the population at time t, P₀ is the initial population, r is the growth rate, and t is the time elapsed.
For this problem, we know that P₀ = 1500, r = 0.07 (since the growth rate is 7%), and we want to find P(8) and P(22) (since we're predicting the population in 2008 and 2022, respectively).
Using the formula, we get:
[tex]P(8) = 1500( 1 + 0.07)^{8} = 2909[/tex]
So we can predict that there will be about 2909 rabbits in the warren in 2008.
To find P(22), we simply plug in t = 22:
[tex]P(22) = 1500 (1 + 0.07)^{22} = 9933[/tex]
So we can predict that there will be about 9933 rabbits in the warren in 2022.

How much will the monthly payment be for a new car priced at $24,530 if the current finance rate is 36 months at 3. 16%? You will finance the 8% TT&L and make a 20% down payment
The monthly payment for a new car priced at $24,530 with the given terms is $630.15.
Calculating the down payment:
20% of $24,530
= 0.20 × 24,530
= $4,906.
Subtracting the down payment from the car price:
= $24,530 - $4,906
= $19,624 (amount to finance).
Adding the 8% TT&L (tax, title, and license) to the amount to finance:
8% of $24,530
= 0.08 × 24,530
= $1,962.40.
So, the total amount to finance
= $19,624 + $1,962.40
= $21,586.40.
Converting the annual interest rate of 3.16% to a decimal:
3.16% / 100
= 0.0316.
Calculating the monthly interest rate:
0.0316 / 12
= 0.002633.
Calculating the total number of payments: 36 months.

The number of tire rotations depends on the distance traveled by the wheel and the circumference of the tire. Different tire sizes would change the circumference of the tire, and therefore the number of rotations of the wheel
1. Compare the original rotations _______ vs new rotations _________.
Without knowing the original and new rotations, answer cannot be provided
2.The number of tire rotations depends on the distance traveled by the wheel and the circumference of the tire. If the wheel traveled a greater distance, the number of rotations would increase, and if it traveled a shorter distance, the number of rotations would decrease. Similarly, if the tire's circumference increased, the number of rotations would decrease, and if the circumference decreased, the number of rotations would increase.
3. Different tire sizes would change the circumference of the tire, and therefore the number of rotations of the wheel. A larger tire size would result in fewer rotations for the same distance traveled, while a smaller tire size would result in more rotations for the same distance traveled.

water is needed to fill 3 jugs and 19 glasses. What is the capacity of one glass?
10
The capacity of one glass is 36/37 liters.
Let's begin by representing the capacity of one jug as "J" and the capacity of one glass as "G". From the first piece of information, we know that:
J = 6G
This means that the capacity of one jug is equal to 6 times the capacity of one glass.
Next, we are given that 36 liters of water is needed to fill 3 jugs and 19 glasses. We can use this information to form an equation in terms of J and G.
The total capacity of 3 jugs is 3J and the total capacity of 19 glasses is 19G. Therefore, we can say:
3J + 19G = 36
Now we can substitute J with 6G (from the first equation) and simplify:
3(6G) + 19G = 36
18G + 19G = 36

Service fee for the over the counter deposit of R700: R10.50
Service fee for the ATM withdrawal of R500: R11.50
To determine the service fee that Tilly will incur for the given transactions,
Over the Counter Deposit of R700:
Tilly is depositing R700, the fee will be:
Fee = R3.50 + (R1.00 per R100) x (R700 / R100)
= R3.50 + R7.00
= R10.50
Therefore, the service fee for the over the counter deposit of R700 is R10.50.
ATM Withdrawal of R500:
The fee for an ATM withdrawal at own bank is calculated as R6.50 + R1.00 per R100.
Since Tilly is withdrawing R500, the fee will be:
Fee = R6.50 + (R1.00 per R100) x (R500 / R100)
= R6.50 + R5.00
= R11.50
Therefore, the service fee for the ATM withdrawal of R500 is R11.50.

What is an algebraic expression?
An algebraic expression is a mathematical phrase that contains variables, constants, and mathematical operations. It may also include exponents and/or roots. Algebraic expressions are used to represent quantities and relationships between quantities in mathematical situations, often in the context of problem-solving.
To solve the equation:
(-3m^ {5}) (-2m^ {4}) = (-6m^ {9})
We can simplify the left side of the equation by multiplying the terms:
(-3m^ {5}) (-2m^ {4}) = (6m^ {9})
Now we have:
6m^ {9} = (-6m^ {9})
To solve for m, we can divide both sides by 6m^ {9}:
m^ {9} = -m^ {9}
Since the powers of m on both sides are equal, we can simplify to:
2m^ {9} =0
Dividing both sides by 2, we get:
m^ {9} =0
Taking the ninth root of both sides, we get:
m = 0
Therefore, the solution to the equation is m = 0.

A paving company is paving the rectangular student parking lot at hamilton high school. the length of the parking lot can be represented as (5 − 7) and the width as (3 + 4) . which expression represents the area of the parking lot?
The expression that represents the area of the parking lot is (5 - 7) * (3 + 4).
How to express the area of the parking lot?The length of the parking lot can be represented as (5 - 7), which simplifies to -2. The width of the parking lot can be represented as (3 + 4), which simplifies to 7. To find the area of a rectangle, we multiply the length by the width.
Therefore, the expression that represents the area of the parking lot is (-2) * 7. Multiplying -2 by 7 gives us -14. So, the area of the parking lot is -14 square units.
However, it is important to note that negative areas do not have practical meaning in this context, as areas are typically positive values. Therefore, the area of the parking lot would be considered 14 square units.

(1 point) Evaluate the integral by reversing the order of integration. 7 STE dedy
the integral by reversing the order of integration. the result will be F(β) - F(α), which is the integral evaluated after reversing the order of integration.
First, let's rewrite your integral more clearly:
∫∫ R 7x dy dx, where R is the region of integration.
To reverse the order of integration, we first need to determine the limits of integration for R in terms of x and y. Let's assume the current limits are a to b for x and c(y) to d(y) for y.
Now, we need to express these limits in terms of y and x. Let's denote the new limits as α to β for y and γ(x) to δ(x) for x.
After finding the new limits, we can rewrite the integral as:
∫∫ R 7x dx dy
Now, evaluate the integral by integrating first with respect to x and then with respect to y:
1. Integrate 7x with respect to x: (7/2)x^2 + C₁(x)
2. Apply the limits of integration for x: [(7/2)δ(x)^2 + C₁(δ(x))] - [(7/2)γ(x)^2 + C₁(γ(x))]
3. Integrate the result with respect to y: ∫[α, β] [(7/2)(δ(y)^2 - γ(y)^2)] dy
4. Apply the limits of integration for y: F(β) - F(α)
The final result will be F(β) - F(α), which is the integral evaluated after reversing the order of integration.

I absolutely hate IQR so can someone help
The interquartile range (IQR) of the given data set is 4.
Interquartile range (IQR) is a measure of variability in a data set that measures the spread of the middle 50% of the data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1).
How to fine the interquartile range (IQR)?To find the interquartile range (IQR), we first need to find the median of the data set.
The median is the middle value of the dataset when the data is arranged in order. In this case, the data set is already in order, so the median is the middle value or the average of the two middle values:
Median = (26 + 28) / 2 = 27
Now, we need to find the first quartile (Q1) and the third quartile (Q3) of the data set.
Q1 is the median of the lower half of the data set, and Q3 is the median of the upper half of the data set.
Lower half: 22, 24, 26
Upper half: 28, 30
Q1 = median of the lower half = (24 + 26) / 2 = 25
Q3 = median of the upper half = (28 + 30) / 2 = 29
Now we can find the IQR:
IQR = Q3 - Q1 = 29 - 25 = 4
Therefore, the interquartile range (IQR) of the given data set is 4.

Find the nth Maclaurin polynomial for the fu f(x) = tan x, n = 3 3 = P(x) I
The 3rd Maclaurin polynomial for f(x) = tan x is P(x) = x + (1/3)x^3.
Recall that the Maclaurin series expansion for tan x is given by:
tan x = x + (1/3)x^3 + (2/15)x^5 + ...
To find the 3rd Maclaurin polynomial, we only need to take the first three terms of the series expansion, since n = 3.
Thus, the 3rd Maclaurin polynomial for f(x) = tan x is given by:
P(x) = x + (1/3)x^3.
Note that the first two terms of the polynomial, x and (1/3)x^3, correspond to the first two terms of the Maclaurin series expansion for tan x.
The third term of the polynomial would correspond to the next term in the series expansion, which is (2/15)x^5. However, since we are only finding the 3rd Maclaurin polynomial, we do not need to include this term.
