At a particular restaurant, each onion ring has 40 calories and each pizza roll has 80
calories. A combination meal with pizza rolls and onion rings is shown to have 800
total calories and 4 more pizza rolls than onion rings. Graphically solve a system of
equations in order to determine the number of onion rings in the combination meal,
x, and the number of pizza rolls in the combination meal, y.
As a result, the combo meal includes 4 onion rings and 8 pizza buns.
What is equation?An equation is a formula in mathematics that expresses the equivalence of two expressions by linking them with the equals symbol =. In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign.
Here,
Let x be the number of onion rings in the combination meal and y be the number of pizza rolls. We can write the following system of equations to represent the given information:
40x + 80y = 800 (the total calories of the meal)
y = x + 4 (the number of pizza rolls is 4 more than the number of onion rings)
We can substitute the second equation into the first equation to solve for x:
40x + 80(x + 4) = 800
40x + 80x + 320 = 800
120x = 480
x = 4
We can use this value to find y:
y = x + 4 = 4 + 4 = 8
So, the combination meal contains 4 onion rings and 8 pizza rolls.

let the random variable Y possess a uniform distribution on the interval(0,1). Derive the
a) distribution of the random variable W=Y^2
b) distribution of the random variable W=Y^(1/2)
To derive the distribution of W, we need to find the cumulative distribution function (CDF) of W, F_W(w), and then find its probability density function (PDF), f_W(w).
a) The distribution of the random variable W = Y^2:
The cumulative distribution function (CDF) of W is given by F_W(w) = P(W <= w), where W is the random variable defined as W = Y^2.
Since Y has a uniform distribution on the interval (0,1), its CDF is given by:
F_Y(y) = 0, for y < 0.
= y, for 0 <= y <= 1.
= 1, for y > 1.
Therefore, the CDF of W = Y^2 is:
F_W(w) = P(Y^2 <= w)
= P(0 <= Y <= sqrt(w))
= F_Y(sqrt(w))
= sqrt(w), for 0 <= w <= 1.
= 1, for w > 1.
Thus, the CDF of W is a monotonically increasing function that maps the interval [0, 1] to [0, 1].
The probability density function (PDF) of W is given by f_W(w) = dF_W(w)/dw. The PDF of W can be found by differentiating the CDF:
f_W(w) = dF_W(w)/dw
= d(sqrt(w))/dw
= 1/(2*sqrt(w))
f_W(w) is defined only for 0 <= w <= 1.
b) The distribution of the random variable W = Y^(1/2):
The CDF of W = Y^(1/2) is given by F_W(w) = P(W <= w), where W is the random variable defined as W = Y^(1/2).
Using the same argument as in part (a), we have:
F_W(w) = P(Y^(1/2) <= w)
= P(0 <= Y <= w^2)
= F_Y(w^2)
= w^2, for 0 <= w <= 1.
= 1, for w > 1.
The PDF of W = Y^(1/2) can be found by differentiating the CDF:
f_W(w) = dF_W(w)/dw
= d(w^2)/dw
= 2w
f_W(w) is defined only for 0 <= w <= 1.

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (0, 5) and (8, -2).
Now,
Since, The equation of line passes through the points (0, 5) and (8, -2).

m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - 5) / ( 8 - 0)
m = - 7 / 8
Thus, The equation of line with slope - 7/8 is,
⇒ y - 5 = - 7/8 (x - 0)
⇒ y - 5 = - 7/8x
⇒ y = - 7/8x + 5
Therefore, The y - intercept of the graph is, 5

how do you find the range algebraically?? Please and thank you if you reply
Answer:
[9, 9+√18.25] ≈ [9, 13.272]
Step-by-step explanation:
You want the range of f(x)= 9+√(6+7x-x^2), determined algebraically.
RangeThe range is the set of values that f(x) may take on. It is the vertical extent of the graph. Here, it will be limited by the possible values the radical may have.
The expression under the radical is a quadratic that opens downward. It will have a maximum at its vertex, and a minimum usable value of 0.
The vertex of the quadratic can be found by putting it in vertex form:
-x² +7x +6 = -(x² -7x) +6 = -(x² -7x +(7/2)²) +6 +(7/2)² = -(x -7/2)² +18.25
The maximum value the quadratic may have is 18.25.
Then the range of values that f(x) may have is ...
9 +0 ≤ f(x) ≤ 9 +√18.25
The range is [9, 9+√18.25] ≈ [9, 13.272].
60th term of -7, -1, 5, 11
Answer:
60th term is 347
Step-by-step explanation:
This is an arithmetic sequence with common difference = -1 - (-7) = 5 - (-1) = 11 -5 = 6
The nth term for such a series is given by
aₙ = a₁ + d(n-1) where d = common difference and a₁ is the first term
Here d = 6, a₁ = -7
So
aₙ = -7 + 6(n-1)
aₙ = -7 + 6n-6
aₙ = 6n-13
60th term is
a₆₀ = 6(60) - 13 = 360 - 13 = 347

The value of the angle m/G is 118 degrees
How to determine the value of the angleIt is important to note that the sum of the angles in a triangle is equivalent to 180 degrees.
From the information given, we have that;
m/G = (8x + 14)°m/H = (3x - 6)° m/I = (« + 16)°Add the angles, we get;
8x + 14 + 3x - 6 + x + 16 = 180
collect like terms
8x + 3x + x = 180- 14 + 6 - 16
add or subtract like terms, we get;
12x = 156
Make 'x' the subject of formula by dividing both sides by the coefficient
x = 156/12

From a sample with n=12, the mean number of television per household is 3 with a standard deviation of 1 television. Using Chebychev Theorem,determine at least how many of the households have between 1 and 5 televisons
Answer:
9
Step-by-step explanation:
Chebyshev's Theorem states that for any given sample, at least 1 - 1/k^2 of the data falls within k standard deviations from the mean.
Let's use k = 2. Then, at least 1 - 1/2^2 = 1 - 1/4 = 3/4 of the households should have between 3 - 2 = 1 and 3 + 2 = 5 televisions.
So, at least 12 * 3/4 = 9 of the households in the sample have between 1 and 5 televisions.
consider a sample with a mean of 500 and a standard deviation of 100. what are the z-scores for the following data values: 550, 660, 500, 440, and 270?

z-score for value 660 = 1.6
z-score for value 500 = 0
z-score for value 440 = -0.6
z-score for value 270 = -2.3
What is the standard deviation?
A standard deviation is a measurement of the data's dispersion from the mean. Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.
We are given a sample with a mean of 500 and a standard deviation of 100.
i.e., µ= 500 and s= 100
The z score distribution is given by;
Z = (X-µ)/s ~ N(0,1)
where X represents the data values;
So, z score for value 550 is;
z score =(550-500)/100 = 0.5
So, z score for value 660 is;
z score = (660-500)/100 = 1.6
So, z score for value 500 is;
z score = (550-500)/100 = 0
So, z score for value 440 is;
z score = (440-500)/100 = -0.6

A store has clearance items that have been marked down by 25%. They are having a sale, advertising an additional 20% off clearance items. What percent of the original price do you end up paying?
The required, we end up paying 60% of the original price.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
If an item is marked down by 25%, then its sale price is 75% of its original price.
If the sale offers an additional 20% off clearance items, then the final sale price is 80% of the sale price.
Multiplying these two percentages, we get:
Final price = 80% of 75% of the original price
Final price = 0.80 × 0.75 × original price
Final price = 0.6 × original price
So the final price that you pay is 60% of the original price.

Wendy will have new carpet installed on her rectangular bedroom floor. The floor is 15 feet in length and 12 feet in width. The carpet costs $27.50 per square yard, and installation costs $4.15 per square yard. Which statement about the total cost of the carpet and installation is true?
a. The total cost is $379.80 since $31.65×12 = $379.80.
b. The total cost is $633.00 since $31.65×20 = $633.00.
c. The total cost is $474.75 since $31.65×15 = $474.75.
d. The total cost is $4,950.00 since $27.50×180 = $4,950.00
Answer: The statement "d. The total cost is $4,950.00 since $27.50×180 = $4,950.00" is incorrect.
The first step is to convert the dimensions of the floor from feet to yards. Since 1 yard = 3 feet, the length of the floor is 15 feet / 3 feet/yard = 5 yards, and the width of the floor is 12 feet / 3 feet/yard = 4 yards. The total area of the floor is 5 yards * 4 yards = 20 square yards.
The total cost per square yard for carpet and installation is $27.50 + $4.15 = $31.65.
The total cost for carpet and installation for the entire floor is 20 square yards * $31.65/square yard = $633.00.
So, the statement "b. The total cost is $633.00 since $31.65×20 = $633.00" is correct.

What is volume?Volume is the quantity of space in a 3D object in arithmetic. A fish tank, for example, is 3 feet long, 1 foot wide, and 2 feet tall. To calculate the volume, multiply the length by the breadth by the height, which is 3x1x2, which is six. As a result, the fish tank has a volume of 6 cubic feet.
Here,
The region R is the upper half of a circle centered at the origin with a radius of 5. By the method of washers, the volume of the solid of revolution obtained by revolving R about the x-axis can be found by subtracting the volume of a cylinder of height "h" and radius "x" from the volume of a cylinder of height "h" and radius "sqrt(25-x²)".
The volume of a cylinder of height "h" and radius "r" is given by V = πr²h.
So, the volume of the solid of revolution can be expressed as:
V = ∫π(sqrt(25-x²)²- x²) dx from x=0 to x=5
Evaluating this integral, we get:
V = π(∫(25-x²)*0.5 dx - ∫x² dx) from x=0 to x=5
Using substitution and integrating, we can obtain the volume:
V = π * (5 * (2 * sqrt(25 - x²) - x²/2))
Evaluating the expression at x=5, we get:
V = π * (5 * (2 * sqrt(25 - 25) - 25/2))
V = π * (5 * (0 - 25/2))
V = -62.83π cubic units.
So, the volume of the solid of revolution is approximately -62.83π cubic units.

A debt of R6 421,00 is due in four years' time. The creditor gives permission to discharge the debt by receiving a payment of R2 287,00 in one year's time and a final payment of RX in seven years' time. The interest rate charged all amounts is 11% per year, compounded quarterly. You can indicate the amounts on the following timeline to assist you in visualizing the problem: 9 B 15 6 years Interest is compounded quarterly. The payment, to the nearest rand, which should be made at the end of the seventh year in order to liquidate the debt, is
The payment (future value), to the nearest rand, which should be made at the end of the seventh year in order to liquidate the debt, is R9,338.80.
How is the future value determined?The future payment to be made at the end of the seventh year is determined by computing the future values in two stages.
The first stage computes the future value before the payment at the end of the first year. The second stage computes the future value for six years.
The future value is computed by compounding the present value at an interest rate.
Current debt = R6,421,00
Compound interest rate = 11% per year
Compounding period = Quarterly
Future Value in 1 Year:N (# of periods) = 4 quarters (1 year x 4)
I/Y (Interest per year) = 11%
PV (Present Value) = R6,421.00
PMT (Periodic Payment) = R0
Results:
Future Value (FV) = R7,156.98
Total Interest = R735.98
Future Value (FV) = R7,156.98
Payment in one year's time = R2,287.00
Balance = R4,869.98

suppose there is a 19.8% probability that a radomly selected person aged 40 years or older is a smoker.A. What is the probability that a randomly selected person aged 40 years or older is female and smokes?B. Would it be unusual to randomly select a person aged 40 years or older who is female and smokes?
A. The probability that a randomly selected person aged 40 years or older is female and smokes is 0.05841.
B. No, it would not be unusual to randomly select a person aged 40 years or older who is female and smokes.
What is probability?
Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is. Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.
When given an event A and an event B, the conditional probability that A will occur given than B has occurred is calculated using this formula -
P(A|B) = P(A and B) / P(B)
Let A be that the person is female and B be that they smoke. It is known that P(B) = 0.295 and let P(A|B) = 0.198.
Use the formula for conditional probability -
0.198 = P(A and B) / 0.295
P(A and B) = 0.198 × 0.295
P(A and B) = 0.05841
The probability that a person aged 40 years or older is female and smokes would happen is 0.05841, which is not less than the usual benchmark of 0.05 to be considered unusual.
Therefore, no, this would not be unusual.
